(Type S) Single Row Deep Groove Ball Bearing |
|  MRC S-type single-row ball bearings have no filling notches and can carry significant radial loads. Because of the uninterrupted raceway grooves and the high degree of conformity between balls and raceways, they can carry substantial thrust loads in either direction, even at very high speeds. Offered open or with single or double shields or seals, as well as with snap-rings in various combinations. Available in 1900, 100, 200, 300, 400 Series.

(Type M) Single-Row Filling-Notch Ball Bearing |
| MRC's single-row maximum capacity "M-type" bearings offer two important advantages over other single-row types when used for heavily loaded positions: They offer maximum radial load-carrying capacity and they have the ability to carry heavy combined radial and thrust loads. MRC M-type bearings are also referred to as a "notch" type because they have a filling notch on one side of the inner and outer rings. Available in 100, 200, 300, & 400 Series.

(R Series, 7000 Series, XLS) Single Row Angular Contact Ball Bearing |
| MRC R-type bearings feature one heavy race shoulder and one counter bored race shoulder on the outer ring. Because of this construction, it is possible to incorporate a greater number of balls than in the deep-groove non-filling notch bearing. MRC R-type bearings have ample radial and thrust capacity for the majority of applications involving heavy radial load, heavy single direction thrust load or both. Available in 1900, 100, 200, 300 Series.

PumPac is an MRC bearing system designed as a unique solution to the common problem of premature thrust bearing failures in high speed centrifugal pumps, as well as other applications where duplexed angular contact ball bearings are used. PumPac is a matched set of bearings, consisting of a 40 degree angular contact ball bearing mounted back-to-back with a 15 degree contact-angle bearing. The 40 degree contact-angle bearing supports the primary thrust load during operation, while the 15 degree contact-angle bearing handles reverse thrust during start-up and shut down, and supports radial loads during normal operation. PumPac bearings are manufactured to ABEC 3 tolerances, with special machined bronze cages, and are high-temperature stabilized. By using PumPac system, ball sliding and shuttling are virtually eliminated, resulting in lower operating temperatures, stable oil viscosity, consistent oil film thickness and longer service life.
The Diamond system, designed for hydrodynamic balanced pumps with low thrust loads, feature ABEC 3 tolerances, high temperature stabilization, and a special heavy duty bronze retainer. Two 15 degree bearing set back-to-back replace the standard PumPac 40 and 15 degree set of bearings. A "V" is etched on each bearing O.D. of the 15 degree bearings. When the bearings are arranged back-to-back, the V's are joined to form a diamond shape.

| Cartridge type bearings are used in applications where space for a lubrication system is limited or conditions demand a larger grease supply inside the bearings. MRC can supply unique versions of this product using special greases or no-drag labyrinth seals, as well as standard versions with SZZC (full contact seals) and SFFC (metal shields). Available in most 200 & 300 Series sizes.

Cylindrical Roller Bearings |
The cylindrical roller bearings listed in this catalog are single-row, radial roller bearings. The length of the rollers in these bearings is usually equal to their diameter. Either the inner or outer ring of each roller bearing has integral flanges on both sides of the raceway for accurate guiding of the rollers. The cage and rollers usually become a unit assembly with the double flanged ring. The cage, if it is land-riding, is piloted on the ground outer diameter or inner diameter land surfaces of the flange shoulders or with only one flange. MRC Bearings manufactures five standard roller bearing types.
Rollers
MRC Bearings roller bearings are assembled with crowned rollers for uniform load distribution along the contact length and to avoid edge loading. The rollers are true cylinders at the center and are ground in varying radii at the end. The specific radii depends on the application. This type of roller also lessens failures caused by misalignment. A special version of crowning developed by SKF; (i.e., logarithmic crowning) can be used to maximize bearing endurance while providing all of the benefits mentioned earlier. MRC Bearings can supply bearings with logarithmic crown rollers upon special request.
Diameters, lengths and other roller dimensions in all roller bearings are held to extremely close tolerances to provide maximum operating efficiency. Standard practice is to furnish bearings with crowned rollers and flat inner and outer raceways. However, raceways can be crowned upon request.
Cages
Cages for MRC Bearings cylindrical roller bearings are custom-engineered. In the one-piece machined cage, the rollers are retained in the pockets by retention features on the cross webs at the cage bore or outside diameter or both depending on the bearing type. Roller drop within the cage pockets can be made sufficiently large to allow cages to be separated from double-flanged inner or outer rings or they can be held to a minimum for ease of assembly. One-piece cages are normally piloted on the land diameter of the double-flanged ring. Construction
Bearings designated by the prefix "MR", offer a marked advancement in roller bearing performance. For those applications not requiring the greater radial load-carrying capacity of the "MR" bearings, MRC Bearings continues to offer the "R" roller bearings.
