Description
Material
Spider polyurethane hardness Shore 98A.
Hub aluminum.
Conical ring carbon steel.
Hub aluminum.
Conical ring carbon steel.
Note
This coupling series is particularly suitable for use in high speed main spindle or drill spindle drives. Before the plug-in assembly, both clamping ring hubs must be fastened to the shafts with the correct tightening torque. Lightly oil the spider to ease assembly.
Assembly
The shaft to hub bore fit should be a transition fit. The play should be max. 0.02 mm. i.e:
shaft Ø 25 k6
bore Ø 25 G6.
Bores smaller than D1/D2 min. are possible, however an optimal transfer of the nominal torque is no longer guaranteed.
shaft Ø 25 k6
bore Ø 25 G6.
Bores smaller than D1/D2 min. are possible, however an optimal transfer of the nominal torque is no longer guaranteed.
On request
Hub bores D1 and D2 with separate tolerance class or range.
