ETP Keyless Bushes - Eliminates Troublesome keys/Keyways

Patented in 1980’s and registered by ETP Transmission AB Sweden, these keyless bushes remain the best hub-shaft connection, even after several decades.

ETP bushes consists of a thin walled cylinder filled by a 'medium'. When this medium is pressurised, they tend to expand the thin walled cylinders and grip both the shaft and the component at the same time.

Mounting of an ETP Bush

To mount any product onto a shaft – Position the ETP Bush on the shaft/product, & just tighten the screw. This tightening increases the pressure on the medium which expands the inner/outer walls of the Bush to grip the shaft and the component simultaneously.

ETP Classic/Classic-R - Available in sizes from 15 – 100 mm (both inch & metric) & in SS construction.
