RBC Cam Followers RBY3 Track Runner Bearings, Yoke Type without Stud, 3.000" Outside Diameter, 1.0000" Inner Diameter
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. The design of the RBC Roller provides the additional benefit of positive, unitized construction. During assembly of the RBC Roller®, the center thrust ring permanently engages a circumferential groove in the stud or inner ring. This design feature ensures integrity of the assembly during handling and operation, and simplifies mounting design. 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.
