The OSI Sharp Chain drive is the most rugged in the industry and features an oversized Eskridge heavy duty torque hub gear reducer that is flange mounted to the massive drive base.  The electric motor is fitted to the machined base and features adjusters for precision coupling alignment.  The motor and torque hub are connected via an input shaft adapter and heavy duty elastomeric coupling.  Our precision machined head sprocket mounts directly to the torque hub and features bolt-on replaceable teeth.  This drive was designed with simplicity and reliablity in mind and provides years of trouble-free service.
