ETP-A R Types- ETP BUSHINGS - MIKI PULLEY VIETNAM

Shaft and hub can be easily and quickly coupled by tightening a clamping bolt located on the flange surface.Fastening is accomplished using fewer bolts than with mechanical systems, and there is no slotting as with mechanical systems, so high-precision coupling with a concentricity of 0.05 mm is possible.

*The rated torque values are those when the thrust is zero and the rated thrust values are those when the torque is zero.

*The rated torque, rated thrust, shaft contact pressure, and hub contact pressure values given are measured values at a temperature of 20°C.

*L1 and L2 are dimensions when the ETP-CLASSIC is mounted. These values may vary slightly depending on the fi t tolerances of the shaft diameter and internal hub diameter.

*The nominal diameter of the clamping bolt M is equal to the quantity minus the nominal diameter of the screw threads times the nominal length.
