Bearing seal. For use in its line of roller bearings, the company introduces heat- and chemical-resistant, spring-loaded Viton "M" seals. They withstand various oils, chemicals, fuels and acids in temperatures up to 400°F. Rex Roller Bearings, Downers Grove, IL. Free info--Circle 752. http://www.OneRS.net/106df-752

Locking collar. Combining the advantages of a standard taper bushing with a keyless locking device, Ring-lok locking collars can be used in v-belt pulleys, timing pulleys, couplings, sprockets and sheaves. Unlike conventional taper bushings, these steel couplings lock to eliminate backlash and wobble. They are impervious to reversing loads and will not vibrate loose. Keyless design circumvents modification. Ringfeder Corp, Westwood, NJ. Free info--Circle 747. http://www.OneRS.net/106df-747

Servo motor. A variety of windings for NEMA 17 brushless DC servo motor integrates with all three-phase servo amplifiers. With quick acceleration and deceleration, the motor achieves no-load operation to 8,000 rpm with peak power output up to 250 watts. Smooth highspeed operation provides peak torque to 33 oz-in. and continuous torque rated at 10 oz-in. Applications for the 1.57-in. sq. motor include semiconductor production. EADmotors, Dover, NH.
