The MSD clamping bush consists of a double-walled, hardened steel sleeve filled with a special pressure medium, a seal, a piston, a compression flange and fastening screws. When tightening the screws, the sleeves expand evenly against shaft and hub, creating a rigid connection. When the screws are loosened, the bush returns to its initial position and can be easily demounted.
Concentricity: ≈ 0.03 - 0.06 mm.
Tolerance: Shaft h8 - k6 (for Prod. No. 615 215 00 only h7), Hub H7.
Temperature range: -30 °C to 85 °C.
T = transmittable torque at axial force of 0, if the screws are fastened with TA.
Fax = transmittable axial force at torque of 0, if the screws are fastened with TA.
Fr = maximum transmittable radial force.
TA = required fastening torque for the screws.
The dimensions refer to bushes before assembly.
