Now you can choose how you want your Bison 750 series gearmotor to be built, using the same high quality components that have set the industry standard for over 40 years. Bison's gears and housings are precision machined to maximize power and service life as well as to minimize wear and maintenance. Lifetime oil lubrication provides efficient continuous operation and resistance to contaminants, ensuring fewer field failures and downtime. Bison's Model 750 line of hollow shaft gearmotors allows hundereds of mounting configurations enabling engineers to optimize their assemblies. Industry standard mounts are available to use with optional accessories to meet your specification! Assembled units are available either in the traditional Bison mounting or the hollow shaft style. Optional shafts and mounting brackets are available as accessories for field installation. To optimize your configuration, select a hollow shaft gearmotor, a mounting style, and a shaft configuration. Following Bison's tradition, all AC units come standard with brake shaft extension for optional AC power-off brakes. DC units have tapped armature shafts to allow mounting of shaft extension kits and optical encoders.
