Square Flange Bearing with 7/8 Inch Bore

This Timken VCJ bearing is a new collectible radial ball unit housed in a cast iron square flange with four mounting holes. It uses an alloy steel GRA014RRB insert with double seals and NLGI #2 equivalent lubricant. The bore measures 7/8 in and the housing centers sit 2 3/4 in apart vertically. It suits enthusiasts preserving industrial hardware history.

Fixed Housing Rated to 6300 RPM and 200 Degrees F

The fixed expansion design holds the shaft securely without axial float under continuous rotation. Double seals retain the factory lubricant across a temperature span from -65 Degrees F to 200 Degrees F. Alloy steel balls and raceways handle sustained speeds up to 6, 300 RPM. Gray cast iron housing resists distortion during long duty cycles.

Direct Replacement for Worn Four Bolt Flange Units

This unit replaces a failed square flange bearing with the same 7/8 in cylindrical bore and four bolt pattern. The back side to center width of .776 in and mount hole spacing must match the existing footprint. The jump is worth it when the original seals have leaked or the raceways show pitting. Collectors gain a new old stock example of Timken power transmission heritage.

Questions about this item

How much heat does the cast-iron housing handle during continuous operation?

The bearing is rated for a maximum operating temperature of 200 degrees F and a minimum of -65 degrees F, so the housing tolerates sustained heat within that range.

What shaft size and mounting pattern are required to install this flange bearing?

It fits a 7/8 inch cylindrical bore and uses four bolt holes on a 2 3/4 inch center-to-center square pattern.

Will the GRA014RRB insert work with older equipment that runs at lower speeds?

Yes, the radial ball insert is fixed and double-sealed with NLGI #2 equivalent grease, making it compatible with legacy machinery operating below the 6,300 RPM limit.
