The 34R-Z Series Parallel Shaft AC Gearmotor is fully enclosed according to IP20 protection standard and features fan cooling, for added output power. The Class "B" insulation system, with Class "A" limits operation, provides prolonged winding and lubricant life. This model also features center ring and endshields in aluminum, for added thermal efficiency and lower weight, unvented gearhousing, industrial lip seals on both motor and output shafts and needle bearings throughout, providing increased radial load capacity and longevity. Additionally, it is perma-lubricated (using semi-fluid grease), and equipped with wide reinforced thermoplastic helical primary gear (offering quiet operation), hardened steel spur gearing on subsequent stages (for added torque and durability), and helical pin, accurately cut on motor shaft (lowering noise and maximizing output). It uses face mounting, and offers optimal motor operation on 115V, 50 Hz. Optional accessories include die cast terminal box kit.
