Precision locating ring for bearing housings

Stable axial positioning in industrial applications

Main description

The FRB 12.5/160 SKF spacer ring is a precision axial locating component designed for use in bearing housings where the housing seat width does not match the bearing width. This solution is widely applied in industrial applications requiring accurate axial positioning, stable bearing operation, and repeatable assembly results.

The FRB spacer ring is used to correctly position a ball bearing or other rolling bearing within a bearing housing, eliminating axial clearance and preventing unwanted axial movement during operation. Proper axial location ensures correct load distribution, reduces vibration, and directly contributes to high durability and extended service life of the bearing unit.

In standard industrial designs, two spacer rings are typically installed per housing, with one ring placed on each side of the bearing. This arrangement provides symmetrical axial support and stable operation under varying loads. If only one spacer ring is required due to design constraints, it should be installed on the same side as the lock nut to ensure effective axial restraint.

The FRB 12.5/160 SKF spacer ring offers precise dimensional accuracy, making it suitable for demanding machinery, gearboxes, drive systems, shaft assemblies, and other industrial units where correct axial bearing positioning inside the housing is critical. Its use helps maintain alignment, supports smooth bearing operation, and reduces the risk of premature wear.

This spacer ring is a proven B2B solution for machine manufacturers and maintenance departments seeking reliability, compatibility with standard bearing housings, and consistent performance in continuous industrial operation.

FAQ - Frequently Asked Questions

What is the purpose of the FRB 12.5/160 spacer ring?
It is used to axially position a bearing in the housing when the bearing width and housing seat width differ.

Can this spacer ring be used with ball bearings?
Yes, it can be used with ball bearings and other types of rolling bearings.

How many spacer rings are normally used per housing?
Typically two, one on each side of the bearing.

When is only one spacer ring used?
If required by the design, it should be installed on the same side as the lock nut.

Where are FRB spacer rings commonly applied?
In industrial bearing housings, gearboxes, drive systems, and machinery assemblies.
