High-speed Rotary Positioner for Welding Machines ※With a moment of inertia of 600

Sankyo's Rotary Positioner for Welding Machines Offers Unsurpassed Speed and Durability The RollerDrive RW Series is a positioner for welding machines. It holds up against shocks that are caused by high-speed positioning and emergency stopping of heavy loads. The oversized hollow output shaft simplifies wiring and plumbing to the equipment to be mounted on the output shaft. The low-profile body allows for compact equipment design. Super high-speed positioning (180° indexing time) : 1.5 sec/2000 kg [RW320] ※With a moment of inertia of 600 kg/m 2. Oversized hollow shaft 360 mm [RW320] Tough...

These units use high-performance lubrication oil. The lubrication oil will remain chemically and thermally stable, but should be replaced every 3,000 hours of operation to prolong the life of the unit. Use the oil level gauge to check the condition of the lubrication. Check lubrication when the unit has stopped. If the oil...
