| Construction | Rubber elements: Lord does not supply hubs, elements only. Metal parts - steel. Flexing element - environmental-resistant elastomer. | |||||||
| General Description | These couplings are customer-assembled, using bonded flexing spools from Lord, bolted between customer supplied metal hubs. Spools should be placed around recommended bolt circle on hub. Coupling assembly has torsional deflection of 2º under rated torque. Shear spool-type couplings provide excellent protection against destructive torsional vibration in high-torque drive systems. Bonded spools can be installed or replaced with minimum effort. | |||||||
| Note |
Maximum recommended misalignment - 1/32 in. parallel, 1º angular. Coupling permits wide latitude in shaft lengths. However, sufficient spacing between shaft ends should be provided to allow for shaft end play. It is suggested that all designs for spool-type flexible couplings be reviewed with Lord Corporation |
