Description
The RBC Roller yoke style cam follower is a reliable and low-maintenance option for applications requiring high reliability. It has a large grease storage cavity and excellent grease retention, making relubrication unnecessary in most operating conditions. The center thrust ring provides end guidance and allows for lower operating temperatures and higher speeds. The cam follower is also tolerant of tracking misalignment and axial loads. It has contacting lip seals for positive exclusion of contaminants and is pre-lubricated at the factory. The cam follower is manufactured with a crowned outer ring, which can minimize thrusting in certain applications but may cause accelerated track wear in well-aligned applications. RBC Bearings has been providing bearing solutions since 1919 and currently has 23 manufacturing facilities worldwide.
The RBC Roller yoke style cam follower was developed for applications requiring a high degree of reliability and maintainability. The space between the two paths of rollers which is created by the center thrust ring provides a large grease storage cavity. This larger than normal ability to store lubricant, in combination with excellent grease retention of the contacting lip seals, makes the RBC Roller virtually maintenance-free. Under most operating conditions relubrication is not necessary. The center thrust ring in the RBC Roller also imparts end guidance to the two paths of rollers. End-guided cylindrical rollers allow the RBC Roller to run at lower operating temperatures and higher speeds. Thrust loading in the RBC Roller is accommodated through contact between outer ring flanges and roller ends, and contact between roller ends and the center thrust ring. This provides the RBC Roller with superior thrust capability. As a result, the RBC Roller is tolerant of tracking misalignment and axial loads that would overwhelm other designs. Contacting lip seals are a standard feature of the RBC Roller. These seals ride on smooth ground surfaces on the inner ring or stud. This sealing system provides positive exclusion of solid and liquid contaminants, and excellent lubricant retention. The RBC Roller is pre-lubricated at the factory with a high quality mineral oil, NLGI grade 2 grease. This cam follower is manufactured with a crowned outer ring. Crowned outer rings are used to minimize outer ring thrusting in applications where the axis of the cam follower is not parallel to the surface of the track or is skewed relative to the direction of travel. However, in well aligned applications, crowned outer rings can cause accelerated track wear. RBC Bearings has been providing bearing solutions to our customers since 1919. A publicly-traded company (NASDAQ: ROLL), RBC currently has 23 manufacturing facilities worldwide, with 18 located in the USA.
