Thin-section BearingsThin-section bearings have small cross-sections with respect to their diameter.  They are designed to save space, lower the weight of a design and reduce friction.  Thin and extra thin-section bearings are available in inch or metric sizes and in chrome or stainless steel.  These bearings are also available with cages for high-speed applications, and with extended inner rings.

Thin-section bearings are manufactured to industry standard sizes. The bearing widths and distance from bore to outside diameter remains constant regardless of the change in bore diameter.

Installation Practices

Standard bearing installation practices can be used in conjunction with thin-section bearings.  Both the inner and outer rings can simply be pushed into place, on the housing and shaft respectively. Installation should only be performed in a clean, contamination free area as thin-section bearings lack seals and grit or other contaminants could get into the bearings and disrupt their performance.

Measurement and Inspection

Due to the large diameters and thin sections of these bearings, it is necessary to address measurement and inspection. To accurately measure the bore diameter and the outside diameter of these thin section bearings special procedures must be followed. Special gages allow three to five measurements around the circumference of the diameter to be taken. These measurements are then averaged to determine the true measurement of the bearing in the unmounted free state. This procedure allows for inherent out-of-roundness.


Thin-section BearingsThin-section ball bearings are generally used in applications with space, weight, and load constraints. Some typical applications for standard thin-section ball bearings include:

Machine tools

Medical equipment

Packaging and textile machinery

Satellite systems

Radar and satellite equipment

Material handling equipment

Aerospace, optical and manufacturing equipment
