Slip torque

As in the table below, the clamping types XBW-C and XBWS-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
XBW-15C2 1
XBW-19C2 1.6
XBW-34C3 5.2 6
XBW-44C2 15
XBW-56C3 25 32
XBW-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 XBW-CXBWS-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.

  • This is a disk type flexible coupling.
  • The stainless steel disk allows eccentricity, and angular misalignment, and end-play.
  • Wide variation of outside diameter φ 15 - φ 104 and bore diameter φ 3 - φ 50.
  • Extra super duralumin (A7075) featuring the highest strength among aluminum alloy is adopted for XBW-C hubs.
  • XBWS-C is the all stainless steel type with stainless steel hubs.

Selection

Selection Based on Shaft Diameter and Rated Torque

The area bounded by the shaft diameter and rated torque indicates the selection size.

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 XBW-C and XBWS-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.
