BOLTTE Aluminum Jaw Couplings - 14-120 mm Outer Diameter

BOLTTE aluminum jaw couplings use 7075 aluminum-alloy hubs and a polyurethane insert for shaft-to-shaft connections. Select the exact model by mounting method, outer diameter, length and available bore range.

Model selection

  • Outer diameter range: 14 mm to 120 mm.
  • Length range: 22 mm to 160 mm.
  • Available bore range is listed separately for every model.
  • Mounting types include set-screw, clamp and three-jaw clamp configurations as shown by model.
  • Models OD80 x L130, OD95 x L126, OD105 x L140 and OD120 x L160 are unanodized by default; the remaining listed models are anodized.

Aluminum jaw coupling selection: fastening affects bore range

Select the hub fastening method before choosing the bore. The OD14 x L22 set-screw and clamp versions illustrate why outside dimensions alone do not identify the correct configuration.

Selection detailWhat to check
Set Screw / OD14 x L22Listed with a 3–8 mm available bore range.
Clamp / OD14 x L22Listed with a 3–6 mm available bore range.
Two shaft endsSpecify Bore 1 and Bore 2 and confirm any keyway and shaft-fit requirements.

Is any polyurethane spider suitable as a replacement?

No. Match the insert geometry, series and size to the actual hubs and confirm operating requirements. Similar colour or outside diameter is not sufficient.

Related selection references

Compare the drawings and intended function; these references are not a statement of direct interchangeability.

Order requirements

  • Enter Shaft Bore 1 and Shaft Bore 2 for the selected model; the two bores may be different within its listed range.
  • If a keyway is required, enter the keyway dimensions.
  • Confirm shaft diameters, alignment, clearance, speed, torque, fastening method and operating environment before installation.

All dimensions are shown in millimetres. Verify both shaft interfaces and the selected model before use.
