Pillow Block Bearing Cast Iron Housing

The Timken RAS 3/4 pillow block bearing is a new-old-stock component listed under sports memorabilia and collectibles. It features a cast iron housing with an eccentric locking collar and a 3/4 inch cylindrical bore. The double-sealed radial ball insert uses NGLI #2 equivalent grease.

Bolt Through Mounting Two Holes

This unit mounts with two bolt-through holes spaced 3 25/32 inches centre-to-centre and a base height of 0.594 inches. The overall height reaches 2.593 inches with a centre height of 1 5/16 inches and an overall length of 5 inches. It fits shafts requiring eccentric locking without set screws.

Operating Range Minus 65 to 200 Degrees F

The bearing operates continuously between minus 65 degrees F and 200 degrees F thanks to the factory lubricant.

Questions about this item

At what temperature does the NGLI #2 equivalent lubricant reach its 200 Degrees F maximum?

The lubricant is rated for continuous operation up to 200 Degrees F before performance degrades.

How much heat does the double-sealed cast iron housing dissipate during all-day operation?

Cast iron housing and double seals contain heat; surface temperature will approach the 200 Degrees F lubricant limit under sustained load.

A 3/4 in cylindrical shaft plus two bolts spaced 3 25/32 in centre-to-centre are needed for the bolt-through base.
