FAG H 311 Adapter Sleeve for Tapered Bore Bearings

Precise Bearing Mounting on Cylindrical Shafts

Stable Fit and High Durability in Industrial Use

Applications in Bearing Units and Housings

Main Description:
The FAG H 311 adapter sleeve is designed for mounting bearings with a tapered bore onto cylindrical shafts. It provides a reliable and practical solution for applications where a direct tapered shaft is not available. This mounting method is widely used in industrial environments requiring accurate positioning and secure bearing fixation.

The H 311 adapter sleeve enables correct axial displacement of the bearing on the tapered seat, allowing precise adjustment of internal clearance. It is commonly used with spherical roller bearings and certain self-aligning ball bearings. When properly installed, it ensures stable operation within a bearing unit or bearing housing, contributing to long service life and reduced vibration.

Manufactured to high FAG quality standards, the sleeve ensures uniform load distribution and strong shaft grip. It supports demanding industrial applications such as gear drives, conveyors, fans, pumps and heavy machinery. Proper mounting using an appropriate lock nut and spanner wrench guarantees secure installation and simplifies future maintenance.

In comparison to direct shaft machining, the adapter sleeve offers flexibility and cost efficiency, especially in maintenance and repair operations. For engineers and procurement departments, FAG H 311 represents a dependable technical component supporting high durability and operational safety in rotating systems.
