Material

• Coupling: Stainless Steel (SUS303).
• Setscrew: Stainless Steel (SUSXM7).

Performance

• Maximum Operating Temperature: 100°C. (approx.)

Features

• Suitable for stepper motors.
• One-piece metallic spring coupling.
• Zero backlash.
• Absorption of parallel & angular misalignments and shaft end-play by spring action.
• Parallel misalignment not absorbed.
• High torsional stiffness and response.
• Identical clockwise & anti-clockwise rotational characteristics.
• Maintenance-free, oil and chemical resistant.

Options

• MWSS couplings can be bored out, but not keywayed.
• Finished products with two different end-bore diameters are available.
• Clean washed SUS304 Stainless Steel for special environment use available.

Other Info.

• All MWSS couplings are supplied with 2 setscrews per hub (except those with a 4mm diameter bore or less which have only 1 setscrew).
• Recommended tolerance on shaft diameters is h6 and h7.
• Non-standard bores and keyways are available on request.
• Important: Couplings and other rotational parts should be protected by covers for safety operation. Also, take note that operation under misalignment exceeding maximum values and excessive torque may result in shorter life of the coupling due to plastic deformation.

Notes:
The maximum torque is two-fold of the rated torque. Select a type in which torque generated during continuous operation does not exceed the rated torque of the coupling.
