Timken 4-Bolt Flange Bearing

The Timken YCJ 2 7/16 flange bearing is a new, 4-bolt mounted unit with a 2 7/16 inch cylindrical bore. It uses a GY1207KRRB radial ball insert made of alloy steel and a cast iron square housing. The double-sealed closure and NLGI #2 equivalent lubricant suit general industrial power transmission applications.

Mounting and common issues

The square housing has a mount hole centre-to-centre height of 5 5/8 inches and a back side to centre width of 1.382 inches. Verify bolt pattern alignment before tightening. Misalignment can overload the fixed expansion type insert. The unit is rated for a maximum speed of 2,800 RPM; exceeding this limit reduces bearing life.

Pre-order checks

Confirm the shaft diameter matches the 2 7/16 inch bore and that the shaft tolerance suits a cylindrical bore fit. Ensure the operating temperature stays between -65 and 200 degrees Fahrenheit. Check that the cast iron housing material is compatible with the mounting surface and environment. Verify the 4-bolt pattern matches the existing equipment.

Questions about this item

How can I confirm the 4-bolt flange bearing is running correctly after installation?

Verify smooth rotation without binding, check that operating temperature stays within the -65 to 200 degrees F range, and ensure speed does not exceed 2,800 RPM under load.

What components are included with the YCJ 2 7/16 unit and what must be sourced separately?

The assembly includes the GY1207KRRB bearing insert, cast-iron square housing, double seals, and NLGI #2 equivalent lubricant; mounting bolts, shims, and alignment tools are not supplied.

Which bore size should I select for a 2 7/16 inch shaft?

Choose the 2 7/16 in bore diameter version; it matches the shaft directly and uses the fixed-expansion GY1207KRRB insert designed for that size.
