Elastomer coupling EKM-VA

TOK Coupling System * Elements available in different torsional stiffnesses * Suited for highest speeds * Adaptation to DIN or SAE flanges or according to specification * Self-centering, backlash-free and maintenance-free * Optional reduction of the torsional stiffness through the use of two elements * Compensation of axial, radial and angular misalignments * Light-weight construction through the use of high-strength aluminium * Variable mounting lengths through telescopic intermediate shafts, freely pluggable * For use up to TKN depending on the application

Spider polyurethane hardness Shore 98A. Hub aluminium. Conical ring carbon steel. Note This coupling series is particularly suitable for use in high speed main spindle or drill spindle drives. Before the plugin 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. On request Hub bores D1 and D2 with separate tolerance class or range.
