LB DB Bellows encoder flexible coupling screw stepper servo motor torque couplings

Steel hubs are zinc plated.
They are precision swaged by a lifetime crimp to unique double loop element made form ELASTACAST polyurethane.
The hubs fix to sharts by metric set screws.
Maximum operating temperature is 80ºC.

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.

introduction
Flexible couplings are offered in the industrys largest variety of stock bore/keyway combinations. These couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications. Applications include power transmission to industrial equipment such as pumps, gear boxes, compressors, blowers, mixers, and conveyors.

Flexible couplings are usually cut from a metal wire rod made of commonly used materials are aluminum, stainless steel, engineering plastics. Flexible coupling using a parallel or helical grooving system to adapt to a variety of bias and precision torque transmission. Flexible couplings usually have good performance and price advantage, and in many stepper, servo system, the practical application, elastic coupling is the preferred product. One-piece design allows flexible couplings to achieve a zero gap torque transmission and without maintenance
