Industrial Collectible Bearing

This new Timken pillow block bearing arrives as a collectible piece rather than a service component. Its cast iron housing and eccentric locking design reflect classic power-transmission engineering. The unit suits display cabinets, technical education aids or brand-focused memorabilia collections.

Operating Envelope Limits

The bearing insert uses alloy steel with double-sealed closure and NLGI #2 equivalent lubricant. Continuous operation is rated between minus sixty-five and two hundred degrees Fahrenheit. These boundaries define the thermal window within which the original component maintained its rated performance.

Mounting and Common Issues

Two bolt-through holes on a five fifty-five sixty-fourths inch centre spacing secure the base to a flat surface. The cylindrical bore measures one and three-quarter inches and requires a matching shaft with an eccentric collar for locking. Misalignment during installation or an undersized shaft are the typical causes of premature wear.

Questions about this item

Which bore diameter should I choose for a 1 3/4 in shaft?

The bearing is manufactured with a 1 3/4 in cylindrical bore, so it fits that shaft size directly without an adapter sleeve.

What does the 200 Degrees F maximum temperature mean for daily operation?

It defines the upper limit for the NGLI #2 equivalent lubricant; sustained running above 200 Degrees F will degrade the grease and shorten seal life.

How does the 5 55/64 in bolt-hole spacing limit mounting options?

The two bolt-through holes are fixed at 5 55/64 in centre-to-centre, so the mounting surface must match that exact pattern or be drilled to suit.
