Overview
The McGill CCYR 3/4 S is a CAMROL® unmounted crowned yoke roller designed for precision cam follower applications. This sealed bearing features a crowned outer diameter and full-complement needle roller construction, ideal for mechanical automation, linear motion, conveyor systems, and rail-following mechanisms. The integrated LUBRI-DISC® seal provides long-term protection against contamination and ensures consistent lubrication without frequent regreasing.
Key Features
- Full-complement needle roller construction – Maximizes load-carrying capacity and shock resistance compared to caged designs
- LUBRI-DISC® integral seal – Prevents metal-to-metal contact, contains grease during operation, and provides blowout protection during relubrication
- Crowned roller profile – Accommodates minor shaft misalignment and reduces edge loading for extended bearing life
- Black oxide finish – All external surfaces protected against corrosion
- Yoke-style mounting – Allows flush installation between supports for compact, accessible layout
