Tapered roller bearing

The Timken 30318 is a tapered roller bearing designed for use as test equipment in electrical applications. It comes packaged as a single unit in a box. The bearing is supplied new and carries a three-year parts warranty with one year of labor coverage.

Maintenance and repair professionals

This bearing suits electricians and technicians who need a replacement tapered roller bearing for diagnostic or test apparatus. It is not intended for buyers who require a complete tool kit or integrated testing instrument. Installers without a press or suitable fitting tools should also look elsewhere.

95 x 200 x 49.5 mm envelope

The critical specification is the physical envelope of 95 mm inner diameter, 200 mm outer diameter and 49.5 mm width. These dimensions determine whether the bearing fits the shaft and housing in the target equipment. Verify all three measurements against the original part before ordering.

Questions about this item

What shaft and housing diameters does the Timken 30318 taper roller bearing fit?

The bearing has a 95 mm bore, a 200 mm outer diameter and a 49.5 mm width, so the shaft must be 95 mm and the housing bore 200 mm for a proper press fit.

Which orientation and preload step is most often missed when installing the 30318 bearing?

The cup and cone must be mounted with the large rib facing the thrust direction and the correct axial preload set with a torque wrench; skipping the preload check leads to early spalling.

When should the Timken 30318 bearing be inspected or replaced in service?

Inspect for noise, vibration or excess heat at regular service intervals; replace if the rolling elements show pitting, the raceways are scored or the 3-year parts coverage period has elapsed.
