Overview
The McGill CYR 3/4 S is a CAMROL-series cylindrical yoke roller bearing engineered for precision cam follower and track roller applications. Featuring full complement needle roller construction and an integrated LUBRI-DISC seal, this bearing delivers high radial load capacity with minimal maintenance. The black oxide finished 52100 bearing steel construction resists corrosion, while yoke-style mounting enables flush installation between supports—ideal for conveyor systems, cam mechanisms, and rail-following equipment.
Key Features
- 52100 bearing steel construction with black oxide finish for corrosion resistance
- Full complement needle roller design provides high radial load capacity and shock resistance
- Sealed LUBRI-DISC integral seal reduces lubrication intervals and minimizes contamination ingress
- Yoke-style mounting allows flush installation between cam tracks and rail guides
- Heavy-sectioned outer race withstands shock loading in high-duty applications
- Induction heat-treated inner studs in roller path for extended bearing life
