Nice Ball Bearings, Inc. produces a full line of ground, semi-ground, and unground bearing assemblies. To choose the exact bearing you need, start with the Nice line of standard inch-dimension,radial, angular contact and thrust ball bearings. Standard series bearings can be customized to include many features that can satisfy the demands of many special applications. They are available with special bores, modified outer ring shapes ,extended inner rings, locking devices, and flanged housings. Standards can be ordered sealed, shielded, or open,and are offered in ground and semi-ground grades to deliver the most cost effective solution for your application.

If you are now designing with only ABEC-1 level or higher bearings, chances are there may be a more economical solution to your application. A Nice application engineer can help you determine the exact precision your design requires,and show you how to take advantage of the savings, selection and special features available in our standard series. Even when a standard isn't the answer, our engineers can deliver an economical,modified standard design that is "fit for purpose."

Three basic ball bearing types are illustrated to assist in proper design selection.

Radial bearings are designed prima-rily to carry loads perpendicular to the axis of the bearing bore. They will also accommodate limited thrust loading or a combination radial and thrust load.
Thrust bearings carry loads applied parallel to the axis of the bearing bore. They are not designed to ac-commodate radial loads
Combination radial and thrust bearings are designed for simultaneously applied thrust and radial loads. Combination assemblies will also carry pure thrust loading; however, they are not recommended for straight radial loads unless provisions are made to keep the inner rings and outer rings in proper contact with the balls.

Many sizes and types of the three basic designs illustrated are available for selection from this catalog. However,if you have an unusual application problem,NICE field and factory engineers will be glad to give you the benefit of their specialized training and broad practical experience.
