BOCA Bearing Expands One-Way & Needle Bearing Series

By Caroline Rees / 15 Jul 2012

The Boca Bearing Company has released new and expanded sizes for one way bearings, needle bearings and needle roller and cage type bearings. Needle & one way bearings are commonly used in pumps, compressors and transmissions and rocker arm pivots.

One way bearings have a small radial section height and are also commonly known as anti-reverse bearings. This design uses the same small radial section as drawn cup needle roller bearings which make better use of reduced space. One Way Bearings are compact, lightweight, operate directly on a shaft and are also suitable for transmitting high torque. One Way Bearings with and without bearing assemblies are offered both in an inch and metric series.

One Way Bearings without bearing assemblies are available in HF, FC and RC versions. One Way Bearings with bearing assemblies are available in HFL, FCB and RCB series. The clutch and bearing assembly can be used in a temperature range from -30°C to 120°C. For a working environment above 70°C, oil lubrication is recommended. The One Way Clutch bearings (OWC), also known as Origin One Way bearings are extra narrow and high performance bearings available as small as a 5.4mm width. Lastly the CSK series is available in two different designs: PP-two keyway notch or the P-one keyway notch series.

Needle bearings use a roller style rolling element to reduce friction of rotating surface and are more compact as the clearance has been reduced. Typically, the needle bearings consist of inner race, needle shaft, which orients the needle roller and an outer race. Needle bearings are primarily used in engine components, such as rocker arm pivots, pumps, compressors and transmissions.

Needle roller and cage type bearings use a roller style rolling element however, they do not include inside and outside races to maximize allotted space. Needle roller and cage type bearings have a larger surface area that is in contact with the bearing outer surface compared to traditional ball bearings. Typically, the needle roller bearings consist of needle cage, which orients and contains the needle rollers, and the needle rollers themselves. Needle roller and cage type bearings are predominantly used in engine components.
