What this bearing is and who fits it

The Timken SAK 1 pillow block bearing uses a 1 inch cylindrical bore and a cast iron housing with two bolt-through holes spaced 4 1/8 inches centre-to-centre. It suits maintenance teams and OEM builders who need a ready-mounted radial ball unit for shafts that match those dimensions.

Temperature limits and sealing

Double seals protect the alloy steel insert and the NGLI #2 equivalent grease across a working range of -65 degrees F to 200 degrees F. Operating outside this window or exposing the unit to aggressive contaminants not excluded by the seal design will shorten service life.

Checks before ordering

Verify that the shaft diameter is exactly 1 inch, that the mounting surface can accept two bolts on a 4 1/8 inch centre distance and that the 2.671 inch overall height and 5.5 inch overall length clear adjacent structure. Confirm the application stays within the stated temperature limits.

Questions about this item

How do I decide between the available bore sizes for this pillow block bearing?

This bearing has a single 1 in cylindrical bore, so no selection is needed — it fits shafts of that exact diameter.

What does the 2.671 in overall height mean when the unit is bolted to a frame?

The center of the shaft will sit 2.671 in above the mounting surface once the two bolt-through holes are secured.

How does the bolt-through mount pattern limit the frame thickness I can use?

The two mount holes are spaced 4 1/8 in centre-to-centre; any frame must accommodate that spacing and accept bolts through its thickness.
