Needle Bearings have a high load carrying capacity with a very small cross section height
Boynton Beach, FL (PRWEB) July 16, 2015
Boca Bearing Company is pleased to announce the release of their new and expanded One Way and Needle Bearing series. 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. These bearings are designed to transmit torque between the shaft and housing in one direction and allow free motion in the opposite direction. 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 HFL series has two integral radial bearings arranged on both sides of a needle roller clutch. They can therefore support radial forces in particularly tight or small areas. Plastic springs (HFL...KF) are available for some sizes. Partially knurled outer rings (HFL...R) are also available upon request. 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.
Boca Bearings also offers the OWC and the EWC One Way Bearing Series. 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. These bearings allow free overrun in the opposite direction; they consist of drawn cup roller clutch and cage and springs. Lastly the CSK series is available in two different designs: PP-two keyway notch or the P-one keyway notch series. The keyway allows the bearing to perfectly and securely fit into the shaft and give the machine, conveyor belt or appliance extra torque.
Needle bearings use a roller style rolling element to reduce friction of a rotating surface. Needle Bearings have a high load carrying capacity with a very small cross section height. They are available with or without an inner ring. The needle rollers are guided parallel to the axis using a cage retainer, thrust bearings can also be supplied with no retainer, which is referred to as a full complement of rollers.
Needle bearings have a larger surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less clearance, or the difference between the diameter of the shaft and the diameter of the bearing, so they are much more compact. The typical structure consists of an inner race (or sometimes merely a shaft), a needle cage which orients and contains the needle rollers, the needle rollers themselves, and an outer race. Needle bearings are heavily used in engine components such as rocker arm pivots, pumps, compressors, and transmissions.
