Authentic Timken Bearing Collectible

This new Timken RCJ 1 7/8 4-Bolt Flange Bearing arrives as a collectible piece of industrial heritage. It displays the genuine gray cast-iron housing and alloy-steel radial ball insert used in power-transmission equipment. Collectors of vintage machinery parts or brand memorabilia receive a factory-fresh example with double-sealed closure and fixed expansion type.

Operating Limits and Lubrication

The bearing is rated for a maximum speed of 3,675 RPM and functions across a temperature range of -65 to 200 degrees Fahrenheit. It comes pre-filled with NLGI #2 equivalent lubricant, so no initial greasing is required. The double-sealed design retains lubricant and excludes contaminants during normal operation.

Included G1114KRRB Insert

The package includes the specific G1114KRRB bearing insert, which matches the 1 7/8 inch cylindrical bore and alloy-steel construction. This insert is the direct replacement component for the RCJ housing, ensuring the collectible remains mechanically complete. No additional adapters, mounting hardware or software are supplied.

Questions about this item

How do I bolt the 4-bolt flange to the frame using the 4 23/64 in center-to-center spacing?

Drill four holes matching the 4 23/64 in height pattern, align the square cast-iron housing, insert bolts through the flange, and torque evenly; the step often missed is checking shaft alignment before final tightening.

When should I re-grease the double-sealed G1114KRRB insert with NLGI #2 equivalent grease?

Re-lubricate via the housing fitting every 2 000 to 4 000 operating hours or per your maintenance schedule; the double seals retain grease but periodic replenishment prevents premature wear.

At what point does the 3 675 RPM speed limit or 200 °F temperature limit become the limiting factor during continuous running?

The 3 675 RPM ceiling is reached first in high-speed applications; sustained operation above this speed generates heat that will then hit the 200 °F thermal limit.
