ETP-MINI is far superior to keyways or setscrews because it allows an adjustable, backlash free joint.Typicalapplications are mounting of hubs on small electrical motors, stepmotors and industrial encoders.As no keyways areneeded, the shaft will not be weakened and the unbalance will be lower, which is very important at high speeds,as the motor bearings manufacturers are sensitive to vibrations.Also available in stainless, ETP-MINI type R, suitable for thefood processing industry etc.

CONSTRUCTION

ETP-MINI consists of two, partly slotted, conical steel sleeves (type R stainless) and clamping screws (type R stainless).

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 type R has one screw more than the normal ETP-MINI in order to transmit the same torque (lower tightening torque for stainless screws).The built-in dimensions are the same.

QUALITIES

•Easy to mount. •Good runout. •Allows wide tolerances. •Available in stainless steel (type R). •ETP-MINI R has stainless cap head screws but stainless hexhead screws are available as accessories, see page 24. The inner sleeve, for ETP-MINI incl.type R, has a light recessclose to the flange in order to create a more uniform surfacepressure to the shaft. 18
