ETP-MINI allows an adjustable, backlash free joint. Its applications include mounting of hubs on small electrical motors, stepmotors and encoders. As no keyways or set screws are needed, the shaft will not be weakened and the unbalance will be lower, which is very important at high speeds, as the motor bearing is sensitive to vibrations. ETP-MINI R is suitable for the food processing industry.

OPERATION: By tightening the screws the inner sleeve is pressed against the shaft and the outer sleeve against the hub thus forming a rigid joint. When dismantling, one or if necessary, two of the screws are moved to the threaded dismantling holes in the flange. By tightening, the sleeves will separate and the joint will loosen.

ETP-MINI R can be also available in stainless steel, which means it has stainless cap head screws but stainless hex head screws can be availed as accessories. As compared to ETP-MINI, ETP-MINI R has one more screw. ETP-MINI consists of two, partly slotted, conical steel sleeves and clamping screws.

This product is easy to mount. It allows wide tolerances.
