Barden Angular Contact Instrument Bearings |
 Angular contact bearings have one ring shoulder partially or totally removed. This allows a larger ball complement than found in comparable deep groove bearings, hence a greater load capacity. Speed capability is also greater.
Angular contact bearings are assembled to a contact angle by varying the radial clearance. Instrument angular contact bearings have nominal contact angles of either 10° or 15°.
Separable and non-separable types are available. In a separable bearing (B type), the cage holds the balls in place so that the outer ring assembly (with cage and balls) can be separated from the inner ring.
Separable bearings are useful where bearings must be installed in blind holes or where press fits are required, both on the shaft and in the housing. The separable feature also permits dynamic balancing of a rotating component with inner ring mounted in place, apart from the outer ring and housing.
Angular contact bearings support thrust loads or combinations of radial and thrust loading. They cannot accept radial loads only — a thrust load of sufficient magnitude must be present. An individual angular contact bearing can be thrust-loaded in only one direction; this load may be a working load or a pre-load. |

Use of ceramic (silicon nitride) balls in place of steel balls can radically improve bearing performance several ways. Because ceramic balls are 60% lighter than steel balls, and because their surface finish is almost perfectly smooth, they exhibit vibration levels two to seven times lower than conventional steel ball bearings.
Because of the unique properties of silicon nitride, ceramic balls drastically reduce the predominant cause of surface wear in conventional bearings (metal rings/metal balls). In conventional bearings, microscopic surface asperities on balls and races will "cold weld" or stick together even under normal lubrication and load conditions. Since ceramic balls will not cold weld to steel rings, wear is dramatically reduced. Because wear particles generated by adhesive wear are not present in ceramic hybrids, lubricant life is also prolonged. The savings in reduced maintenance costs alone can be significant.
Even greater performance can be realized by using Cronidur® 30 Ceramic Hybrids.
- Ceramic hybrids can boost running speeds by 40% to 50%.
- Ceramic hybrids run significantly cooler than standard steel ball bearings.
- Lower operating temperatures help extend lube life.
- Ceramic hybrids will out last steel ball bearings up to five times.
- Ceramic hybrids have higher rigidity characteristics
- Ceramic hybrids are quieter running

Barden Deep Groove Instrument Bearings |
Deep groove ball bearings have full shoulders on both sides of the raceways of the inner and outer rings. They can accept radial loads, thrust loads in either direction, or a combination of loads.
The design of deep groove bearings make them suitable for the addition of closures which help exclude contaminants and retain lubrication. Besides single deep groove bearings with closures, Barden also offers duplex pairs with seals or shields on the outboard faces.
Flanged bearings are especially useful in through-bored housings. The inboard side of the flange provides an accurate positioning surface for bearing alignment, eliminating a need for housing shoulders or shoulder rings.
Deep groove bearings are available in many sizes, with a variety of cage types. Because of their versatility, deep groove bearings are the most widely used type of bearing. |

Barden/FAG engineers developed the ZSB small ball angular contact shielded series spindle bearings to allow machine tools to operate at higher running speeds (up to 20% more) while maintaining optimum work piece finish characteristics. The small ball feature of the ZSB series allows a greater number of balls to be used, increasing bearing stiffness, which leads to improved machining accuracy at higher speeds.
Barden's ZSB series offers optional integral shields which reduce the chances of bearing failure through contamination and prolong lubricant life when bearings are grease lubricated. Shields are available as an option on all sizes.
The inner ring outside diameter land is removed from one side and the outer ring bore diameter land is removed from the opposite side. This allows for optimum exposure and flow through characteristics for air/oil lube systems, and increased storage areas for shielded grease lubed bearings. Also available in HS(S) and HC(S) types. |

Barden Angular Contact Spindle Bearings |
Angular contact bearings have one ring shoulder partially or totally removed. This allows a larger ball complement than found in comparable deep groove bearings, hence a greater load capacity. Speed capability is also greater.
Angular contact bearings are assembled to a contact angle by varying the radial clearance. Spindle size Barden angular contact bearings have nominal contact angles of either 15° or 25°. The smaller angle delivers better radial capacity and rigidity, the larger angle is better for axial rigidity.
Separable and non-separable types are available. In a separable bearing (B type), the cage holds the balls in place so that the outer ring assembly (with cage and balls) can be separated from the inner ring.
Separable bearings are useful where bearings must be installed in blind holes or where press fits are required, both on the shaft and in the housing. The separable feature also permits dynamic balancing of a rotating component with inner ring mounted in place, apart from the outer ring and housing.

FAG Cylindrical Roller Bearings |
These bearings are typically used in combination with double direction angular contact thrust bearings in applications where radial stiffness, high radial capacity and high precision support is required.
Double row cylindrical roller bearings have a high load carrying capacity because of the high number of cylindrical rollers in each row, and the exclusive optimized roller crown profile which results in the best load distribution.
A single row bearing (N10, N19) would be most commonly used as the "floating" bearing in combination with a set of preloaded angular contact spindle bearings.
For axial loads, double direction angular contact thrust bearings, Series 2344 are used in combination with Series NN30 bearings.
The cage is of solid brass construction, making this bearing suitable for rugged applications. They are particularly suited for the demands of turning spindles. Available with ceramic rollers for higher speeds.
Cylindrical roller bearings can be lubricated with either grease or oil. Double row bearings feature a lubricating groove and lubricating hole in the middle of the outer ring. |

Barden Deep Groove Spindle Bearings |
Deep groove ball bearings have full shoulders on both sides of the raceways of the inner and outer rings. They can accept radial loads, thrust loads in either direction, or a combination of loads.
The design of deep groove bearings make them suitable for the addition of closures which help exclude contaminants and retain lubrication. Besides single deep groove bearings with closures, Barden also offers duplex pairs with seals or shields on the outboard faces.
Extra wide, or cartridge width, deep groove bearings are available in Series 9000 for installations requiring lengthy operation without re-lubrication. Series 9000 bearings have more interior free volume and therefore hold more grease.
Deep groove bearings are available in many sizes, with a variety of cage types. |

FAG Double Direction Angular Ball Screw Support Bearings |
For optimum performance, machine tool spindle bearings must exhibit high rigidity as well as high precision, allowing only slight deflection under load.
Double direction angular contact thrust ball bearings achieve a very high level of rigidity through their internal design and pro-load.
Double direction angular contact thrust ball bearings series 2344-2347 should be used in combination with cylindrical roller bearings because they carry only thrust loads. Use of a cylindrical roller bearing in combination with a double row cylindrical roller bearing offers the advantage of supporting both axial and radial forces separately.
Double direction angular contact thrust ball bearings with 60° contact angle are well suited for applications requiring high axial stiffness.
They are manufactured to precision tolerances, and match the mounting dimensions of the NN30 Series double row cylindrical roller bearings. They feature a solid one piece brass cage which is ball guided.
Double direction angular contact thrust ball bearings can be lubricated with either grease or oil. The outer ring O.D. has a lubricating groove in the center with lubricating holes. The application of the lubricant between the two rows of balls allows optimal distribution of lubricant to both raceways. |

Barden Cronidur® 30 Spindle Bearings |
Cronidur® 30 is a spindle bearing material developed by Barden's parent company FAG, in  collaboration with Bochum University and VSG Energie Technik.
It is now available in ceramic hybrid spindle bearings.
Cronidur® 30 is a martensitic through-hardened steel that, because of its alloy composition — carbon, nitrogen, chromium and molybdenum — exhibits exceptional corrosion resistance, strength, durability and high-temperature hardness. Cronidur® 30 is suitable wherever extreme toughness and long life are required.
Tests have shown that Cronidur® 30 spindle bearings can achieve speeds of 2.0 million DmN with grease lube at stable temperatures, while conventional hybrid bearings reached their limit at 1.5 million DmN. At contact pressures of 360,000 PSI under boundary lubrication conditions life values exceed 52100 bearings by a factor of 10. Cronidur® 30's corrosion resistance — is 100 times better than that of 440C, long considered the standard material for corrosion resistant bearings.
