AL Models

These couplings have simpler designs that sandwich a rubber buffer (nitrile rubber) between two hubs. The hub is lightweight, being made of aluminum alloy.Mounting on a shaft is easy. Simply hold a straight-edge to the hub periphery to center it. One source of appeal is that its simple construction means lower cost.

*Max. rotation speed does not take into account dynamic balance or mounting misalignment.

*The moment of inertia and mass are measured for the pilot bore.

*"Pilot bore" refers to center processing. Minimums and maximums for d1 and d2 are values at the MIKI PULLEY standard hole-drilling standards.

*The value marked *1 leaves a 1 mm space for the thickness of the spider body.

*The ø11 or below requirement under the new JIS standards and ø11 requirement for the new motor standards are the same as the old JIS standards (class 2).

*For AL-035, the tolerance is +0.05+0 regardless of bore diameter. The set screw size is M3.
