Slip torque

As in the table below, the clamping types XBS-C and XBSS-C have different slip torque according to the bore diameter. Take care during selection.

Unit : N・m

Part Number Bore Diameter (mm)
3 4 6 8 10 11 14 15
XBS-15C2 1
XBS-19C2 1.6
XBS-34C3 5.2 6
XBS-44C2 15
XBS-56C3 25 32
XBS-68C5 80 100

These are test values based on the conditions of shaft dimensional allowance: h7, hardness: 34-40 HRC, and screw tightening torque of the values described in XBS-CXBSS-C dimension tables. They are not guaranteed values.
Slip torque changes with usage conditions. Carry out tests under conditions similar to actual conditions in advance.

Change in static torsional stiffness due to temperature

This is a value under the condition where the static torsional stiffness at 20°C is 100%.
The change of XBS-C and XBSS-C in torsional stiffness due to temperature is small and the change in responsiveness is extremely small. If the unit is used under higher temperature, be careful about misalignment due to elongation or deflection of the shaft associated with thermal expansion.
