R Series Ball Bearings
The 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.
