Miniature 4 Slit Flexible CouplingAluminium with Set Screw Fixing : 0.1 - 8Nm : 2 - 16mm Bores

MWS

MaterialCoupling: Aluminium A2017 with anodised coating.Set Screw: SCM435, black oxide coating (may be replaced with Stainless Steel).Maximum Operating Temperature: +100°C (Approx.).

OrderingAdd bore size required to end of part number eg. MWS-25-8X10 (bored Ø8mm & Ø10mm).

ExtrasThese couplings can be bored out. For keyways please contact Ondrives.Finished products with two different end-bore diameters available.

Other Info.All sizes are supplied with setscrews (2 per coupling except hubs with bore diameters of 4mm or less which have 1 setscrew). Recommended tolerance on shaft diameters is h6 and h7.Non-standard bores and keyways machined 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.

Features• Suitable for stepper motors• One-piece metallic spring coupling• Zero backlash • Absorption of angular misalignment 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.
