Pillow Block Bearing 1 7/16 in Bore

This Timken pillow block bearing uses a radial ball insert made from alloy steel and a cast-iron housing. It fits a 1 7/16 in cylindrical bore and is double sealed with NGLI #2 equivalent lubricant. The unit operates between -65 and 200 degrees F. It mounts with two bolt-through holes spaced 5 1/8 in center-to-center.

Upgrade From Worn or Open Bearings

Replace this unit when an existing pillow block shows seal wear, lubricant loss or excessive play on the same shaft size. The jump is worth it if the current bearing runs hotter than 200 degrees F or cannot stay sealed in dirty environments. It is not for applications that need a different bore diameter, a four-bolt mounting pattern or a higher temperature rating than 200 degrees F.

Check Shaft Size and Mount Spacing

Verify that the shaft measures 1 7/16 in and that the frame provides two bolt holes on a 5 1/8 in center-to-center pattern. Confirm the base height of .72 in and overall height of 3.75 in clear surrounding structure. Ensure the operating temperature stays within the -65 to 200 degree F range.

Questions about this item

What bolt spacing does the 1 7/16 in bore pillow block need for mounting?

The two bolt-through holes are spaced 5 1/8 in center-to-center, so the mounting surface must match that distance.

Which step is often missed when installing the double-sealed radial ball insert?

Align the bearing squarely before tightening the mounting bolts; forcing it crooked binds the seals and shortens life.

How often should the NGLI #2 equivalent grease be replenished in the alloy steel insert?

Relubricate on a schedule suited to load and temperature between -65 and 200 °F; the double seals hold grease but do not make it maintenance-free.
