Collector-Grade Pillow Block Bearing

This Timken RAK pillow block bearing arrives new as a collectible piece of industrial heritage. The cast-iron housing and alloy-steel radial ball insert showcase classic power-transmission engineering. It appeals to enthusiasts who preserve vintage mechanical components or display historic hardware brands.

Cast-Iron Housing With Bolt-Through Mounting

The housing measures 1.311 in base height and 6.062 in overall height, finished in black for corrosion resistance. Two bolt-through holes on an 8 in centre-to-centre pattern allow secure attachment to flat surfaces. Double-sealed closures protect the internal bearing from contaminants during handling or static display.

Fixed Bore And Temperature Limits

The cylindrical bore is set at 2 11/16 in, so the unit fits only shafts of that exact diameter. Lubrication is rated for NGLI #2 equivalent grease with an operating window from -65 Degrees F to 200 Degrees F. Overall length reaches 10.5 in, defining the footprint required for mounting or shelving.

Questions about this item

How does the 2 11/16 in bore diameter limit the shaft sizes this pillow block bearing can accept?

The 2 11/16 in cylindrical bore fits shafts of that exact diameter; undersized or oversized shafts will not seat correctly in the alloy-steel radial ball insert.

What mounting dimensions does the cast-iron housing require for bolt-through installation?

The housing has two bolt-through holes on an 8 in center-to-center length and a 1.311 in base height, so the mounting surface must match that pattern.

Which step is often missed when installing the eccentric locking collar on this double-sealed bearing?

After sliding the unit onto the shaft, the eccentric collar must be turned in the direction of shaft rotation and then locked with the set screw; skipping the directional turn leaves the inner ring loose.
