New SureMotion jaw/spider, double loop, Oldham, and beam-style servo drive couplings are now available. Jaw/spider clamp-style couplings have hub bores from 3/16" to 32mm with polyurethane center "spiders" for shock and vibration reduction. Double loop couplings provide high torsional rigidity in a one-piece design and are available in 1/8" to 16mm bore sizes. These couplings offer outstanding resistance to acids, alkalis, solvents, oils and grease. Oldham drive couplings with aluminum hubs, bore sizes from 1/4" to 1" and Delrin™ center discs, provide electrical isolation, absorb shock and isolate vibration. Beam-style stainless steel servo couplings, with zero backlash and torque rating up to 300 lb-ft., combine flexibility with strength and torsional stiffness for applications up to 10,000rpm. SureMotion drive couplings start at $10.50.
