Timken SAS 3/4 Pillow Block Bearing

The Timken SAS 3/4 pillow block bearing is a radial ball unit with a 3/4 in cylindrical bore and double-sealed closure. It suits maintenance crews and OEM builders who need a cast-iron housed bearing for moderate-speed shaft support in conveyor, fan or agricultural equipment.

Bolt-through mounting with two holes

The housing uses a bolt-through mount with two holes on a 3 49/64 in center-to-center length. Align the base to the mounting surface before tightening; misalignment can load the inner ring unevenly and shorten seal life. The NGLI #2 equivalent grease is factory-filled, so no initial lubrication is required.

Check shaft tolerance and operating limits

Verify that the shaft diameter matches the 3/4 in bore tolerance for a secure press fit. Confirm the application stays within the -65 Degrees F to 200 Degrees F temperature range and that the 1 5/16 in center height fits your frame geometry. Buyers needing a different bore size or a four-bolt mounting pattern should look elsewhere.

Questions about this item

How can I confirm the bearing is rotating smoothly after installation?

Rotate the shaft by hand and listen for quiet, even movement without binding or grinding; the double-sealed radial ball insert should turn freely within the cast-iron housing.

What components are included and what must I supply?

The pillow block bearing with alloy-steel radial ball insert, cast-iron housing, double seals and NGLI #2 equivalent lubricant are included; you must provide mounting bolts for the two bolt-through holes.

Which SAS version should I choose for a 3/4 in shaft?

Select the SAS 3/4 model with a 3/4 in cylindrical bore; it matches the shaft and provides the listed 1 5/16 in centre height and 2.515 in overall height.
