Material

• Body: Anodised Aluminium alloy (A2017).
• SetScrews: SCM435 black oxide coating.
• Sleeve: Polyurethane.
• Sleeve Durometer Hardness (Shore A): 98 (Red disc - RD), 92 (White disc - WH), 80 (Blue disc - BL).
• Operating temperature Range: -20°C to +60°C.
• Rated and max. torque capacities are decreased in case of use in high ambient temperatures. If ambient temperature exceeds 30°C, adjust torque capacity.

Features

• For use with stepper motors and some servo and general purpose motors.
• Excellent flexibility - torsional vibration can be absorbed as well as parallel and angular misalignments.
• Excellent resistance to oil, and electrical insulation.
• Can transmit generally higher torque than metallic spring couplings.
• Compression type coupling assembled by pressing an elastic polyurethane sleeve into hubs on both sides for zero backlash in low torque application.
• Can be used as a flexible coupling in a high torque applications.
• Identical clockwise & anti-clockwise rotational characteristics.
• Finished bore product - models with two different end bores also in stock.
• Setscrews supplied. Bores of 3 or 4mm only have 1 setscrew.
• Recommended tolerance on shaft diameters is h6 and h7.
• Complete absorption of eccentricity, angularity and end-play by spring actions.

Ordering:

The MJT coupling can be bored out, but not keywayed.
MJT-K Keywayed couplings can be ordered as specials, but a minimum order quantity may apply.

† Moment of inertia and mass figures are based on maximum shaft bores.
