Accurate Bushing YR-7/8 Cam Yoke Roller Needle Roller Bearing

Product Description

The ACCURATE BUSHING YR-7/8 is a non-crowned cam yoke roller designed for use in linear and rotary motion applications where controlled track following and load transfer are required. Built around a needle roller bearing, this cam follower delivers a 2,140-pound dynamic load capacity and a 4,170-pound static load capacity in a compact form factor. The carbon steel construction provides durability under continuous cycling loads. Maintenance technicians, millwrights, and mechanical assemblers typically install this type of component in production machinery, conveyor systems, and cam-driven mechanisms.

This cam yoke roller is suited for light-to-medium industrial machinery where a yoke-style mounting is specified. The non-crowned roller profile makes it appropriate for applications requiring full-face contact with flat or parallel tracks, as opposed to crowned profiles used on angled or misaligned surfaces. The unsealed design is common in controlled environments where external lubrication access is maintained as part of a routine service schedule.

Key Features

• Non-crowned roller profile for full-face track contact on flat or parallel surfaces
• Needle roller bearing type for high radial load capacity relative to envelope size
• 2,140-pound dynamic load capacity and 4,170-pound static load capacity
• Carbon steel construction for durability in cyclic-load applications
• Unsealed closure type for externally lubricated service environments
• Compact overall width of 0.5625 inches for space-constrained assemblies

Compatibility

Designed as an OEM-style replacement or service component for yoke cam follower applications specifying a 0.25-inch bore diameter, 0.875-inch roller diameter, and 0.5-inch roller width with needle roller bearing construction.

Installation Notes

Installation of cam yoke rollers is typically performed by millwrights or mechanical maintenance technicians. De-energize and lock out all power to the machine before disassembly per OSHA lockout/tagout procedures. Verify bore fit and yoke clearances against the original equipment specification before pressing or threading the component into place. Because this is an unsealed bearing, ensure a lubrication schedule is established to prevent premature wear.
