COMMONLY USED BEARINGS:

Indoff uses a variety of different bearings depending on the application. Generally 4 different styles are offered.

Precision Bearings

Precision bearings are offered as an option to Indoff rollers. These bearings are suitable for any speed, but are typically used when speeds exceed 400 rpm or when conveying heavy loads. These bearings have hardened and ground balls, raceways and retainers. They are available shielded or sealed. These are ABEC-1 bearings and come either grease packed or oiled.

Semi-Precision Bearings

Semi-Precision bearings are typically used for higher speed applications up to about 400 rpm. These bearings have hardened raceways and hardened steel balls with a retainer to separate the balls. Generally give longer life and are quieter than non-precision.

Non-Precision Bearings

Non-precision bearings are typically used for slow to moderate speed applications. These bearings have stamped outer races, carbon steel balls and ground raceways. As a rule of thumb, they do not last as long and are noisier than precision and semi-precision bearings.

Commercial Grade Stainless Steel

These bearings are used for roller that are going into corrosive environments. Machined raceways and series 300 stainless steel balls are good for light to moderate loads and can be used for high speeds.
