MAV Locking Assemblies and Shrink Discs are innovative solutions that address the limitations of traditional keyways and splined locking systems.

Locking Assemblies simplify the assembly process, eliminate stress concentrators, and provide customized solutions for various applications.

Range covers different widths and end finishes, Quick Release, etc. Covers an exhaustive range, from 6 to 600 shafts.

By relying on friction rather than relying on keys or splines, MAV Locking Assemblies eliminate the need for complex machining processes and provide a simpler assembly and disassembly experience.

Shrink Discs are available in the range of 14 to 600 mm shafts.

MAV specializes in providing Special Locking Assemblies tailored to specific requirements. They employ their in-house Design and specialized software to develop custom solutions to suit every need.

ETP Classic Bushes were the first to be introduced, followed by ETP Classic R (in stainless steel for food & chemical industries.)

ETP Express / ETP Express R

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

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.

ETP Mini

To meet the demands of the industry – ETP also offers MINI (for shaft diameters from 6 to 14mm), based on mechanical principles.

ETP Hyloc

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

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.
