• These products replace keys and keyways, for connection of a shaft to a hub. Keyway transmission increases the cost due to various operations involved including downtime, machining time, lateral shifting of key-ways in the process, etc.
• There are ETP keyless locking device models designed to solve specific requirements such as high transmittable torque and special applications.
• They are the best solution where keyways and tapers can weaken due to excessive usage or when high torque and a good runout are required.
• ETP Classic and Express models are also available in stainless steel for corrosion protection.

ETP-CLASSIC is available as standard for shafts, also imperial and a short version, (type S). Also available in stainless steel ( type R). The small number of clamping screws with low tightening torque, makes the mounting/ dismantling procedure fast and easy

Construction:

• ETP-CLASSIC is a hydraulic connection which consists of a double-walled hardened steel sleeve, filled with a specially developed pressure medium, sealing ring, piston, pressure flange and cap head clamping screws. ETP-CLASSIC type R is made of stainless steel and has hex head stainless steel clamping screws. This in order to facilitate easy cleaning, essential within food processing.

• When tightening the screws, the sleeve expands uniformly against hub and shaft and creates a rigid joint. When loosening the screws, the sleeve returns to its original measurements and can easily be dismantled. ETP-CLASSIC type R has a few more clamping screws, as the tightening torque is lower for stainless steel screws.

Advantages:

• Easy and accurate positioning
• Short lengths and outside diameters - making them compact
• Quick mounting
• Good run out (both axial and radial)
• Speedy assembly/Dismantling
• Mounting and dismantling is fast
• Service and maintenance are also quick

• Small built-in dimensions
• Mounting and dismantling is fast
• Fine adjustment of the hub can be made during mounting
• Low tightening torque and a small number of screws makes the mounting easy
• Good concentricity, also after several mountings
• Hex head screws available as accessories.
