SureMotion drive couplings from AutomationDirect compensate for shaft misalignment whether the misalignment is an intentional or unintentional part of design. The drive couplings are available in four styles: jaw/spider, double loop, Oldham, and beam-style servo; bore reducers are also offered to fit a coupling when the exact bore is not available.
The SureMotion clamp-style jaw/spider coupling has 14 to 65 mm aluminum hubs and bore diameters ranging from 3/16 in. to 32 mm. Polyurethane center “spiders” are available in different durometers for different degrees of shock and vibration reduction.
Double loop coupling hubs are made of series 300 stainless steel with corrosion protection against acids, alkalis, solvents, oils, grease, and ozone. Double loop couplings are available in 10 mm to 40 mm hub sizes.
Oldham drive couplings feature aluminum hubs in 19 mm to 57 mm sizes and have a large radial misalignment capability.
Available beam-style servo couplings are stainless steel set-screw couplings, which feature the flexibility of a bellows coupling plus the torsional stiffness and strength of a disc coupling. Ideal for high-speed applications up to 10,000 rpm, beam-style servo couplings are corrosion-resistant, have zero backlash and a maximum torque of up to 300 lb-ft.
Bore reducers are available for use in all drive coupling hubs to reduce bore size. The hardened stainless steel split-collar design provides 25 percent greater holding power than standard split collars.
