R Series Ball Bearings

R Series Ball BearingsThe R-Series ball bearings, named for their numerical model numbers, are also known as our Precision Inch Series ball bearings. More specifically R-Series bearings are radial ball bearings with inch dimensions available from ⅛" through 1½ inch bore sizes.

The design uses Conrad construction which is a type of non-separable deep-groove ball bearing, with symmetrical inner and outer raceways. Most notably, this constuction allows an axial thrust load in addition to radial loads. The R-Series is available in standard and flanged configurations and is also available in open, shielded and sealed arrangements. Seals are readily available in PTFE and Buna-N-Rubber (contact and light contact) in most sizes. With the design of the ball complement and availability of a wide variety of retainers makes the R-Series a favorite in the design of high-speed motor applications among others.

If you need help in selecting the best products for your particular application, please remember that design engineering and application assistance are available from AST as part of our value-added services designed to make your job easier.
