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.
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.
Quick Mounting
Easy & accurate to position
Saves space along the shaft
Good runout
Small built-in dimensions
Quick dismantling
ETP Classic Bushes were the first to be introduced, followed by ETP Classic R (in stainless steel for food & chemical industries.)
To enable faster assembly/dismantling, ETP improved the basic concept & introduced ETP Express. This model has only a single screw to tighten/release the bush from the shaft. Suitable for shaft sizes from 15 to 100 mm, and in inch series. Also available in SS construction – Ideal for Food/Pharma/Printing & Chemical industries.
ETP-POWER is available as standard for shafts 15-40mm. Runout ≤0.03mm. Number of mountings 200-500(size dependent). ETP-POWER combines quick mounting with a high radial load capacity due to the specially developed pressure medium.
To meet the demands of the industry – ETP also offers MINI (for shaft diameters from 6 to 14mm), based on mechanical principles.
ETP-HYLOC is designed for Heavy & Dynamic loads (for shaft diameters from 50 mm onwards), Backlash-free, ensuring high radial force capacity, Quick changes, Accurate positioning combined with Good runout. Very successfully being used in India at Jindal Steel Power, Bhushan Steel, Tri Metal – in their Tube rolling mills for quick change of rollers in the Tube rolling mill. Proven, acclaimed & used successfully Internationally.
ETP-OCTOPUS is available as standard for shafts 30-100mm.Number of mountings 100,000 - 500,000.(pressure dependent). ETP-OCTOPUS is easy to build in, as no hub is required, and allows for fast, frequent and accurate positioning. Cutomized designs are offered on request.
