Pillow Block Bearing 25 mm Bore

This pillow block bearing is a new cast-iron housed unit designed for industrial power-transmission applications. It suits maintenance teams and equipment builders who need a ready-to-mount radial ball bearing with a fixed expansion type.

Double-Sealed Alloy-Steel Insert

The bearing insert is made from alloy steel and features a double-sealed closure that retains grease lubricant while excluding contaminants. Its cylindrical bore measures 25 mm and the unit operates between -40 °C and 120 °C.

Bolt-Through Mounting on 105 mm Centres

Two bolt-through holes spaced 105 mm centre-to-centre in both length and width secure the housing to a flat mounting surface. The 33.3 mm centre height aligns the shaft without additional shimming, freeing up design space for adjacent drive components.

Questions about this item

What does the 33.3 mm center height mean once the pillow block is bolted to a machine frame?

The 33.3 mm center height places the shaft centreline exactly 33.3 mm above the mounting surface, so the driven shaft aligns with other components at that height.

How does the 25 mm cylindrical bore and eccentric locking collar fix the shaft in practice?

The 25 mm cylindrical bore accepts a 25 mm shaft, and the eccentric collar locks by rotating against shaft rotation, creating a secure grip without set-screw damage.

What bolt pattern and clearance does the cast-iron housing need for mounting?

Two bolt-through holes on a 105 mm by 105 mm square pattern, with a 38 mm wide base and 15 mm base height, require matching drilled holes and a flat mounting pad.
