SUS / Centering / 2D CAD / 3D CADInstallation Manual

Features

  1. Total 24 standard models for shaft diameters ranging from φ8 to φ50mm.
  2. Fully stainless steel construction satisfies clean room and vacuum environments.
  3. Prevents the off-centering of outer ring due to centering function.
  4. The tapered portion is difficult to come off due to the gradual taper design.
  5. Straight through-hole bore processing is possible.
  6. Wide selection of hub due to thinnes and low surface force.

Comparison of allowable

transmission torque

Comparison of allowable transmission torqueMecha-lock MSA series have effective corrosion resistance since the screw are also stainless steel. In addition the counter lock, a Mecha-lock's feature, makes hub bore as a through-hole.

  • Mecha-lock can be manufactured for other motor shaft tolerances (j6.k6.m6). Shaft tolerance should be specified after selecting the type when ordering. [example : MSA-20-38(m6)]
  • MSA-35-57 is applicable to motor shaft tolerance +0.01.
