"Zero Backlash Technology" allows for quick setting times and precise positioning! The speed variations during operation are minimal, enabling high-precision synchronization as well.
The "RA Series" is a high-precision zero-backlash positioner that features a wedge-shaped input shaft rib that contacts the roller follower under pre-load conditions, completely eliminating backlash. The input shaft made of alloy steel is manufactured using new processing theories and equipment to meet strict precision requirements. It is also balanced to suppress self-excited vibrations during high-speed rotation. Additionally, with a rolling element bearing structure, it transmits torque while rotating, and due to the rolling contact, it maintains initial precision for a long period of use. 【Features】 ■ Pre-load is adjustable via a mechanism on the input shaft side. ■ Quick settling time allows for precise positioning. ■ Minimal speed fluctuations during operation enable high-precision synchronization. ■ Improved speed and repeat accuracy allow for a thinner and more compact drive unit layout. *For more details, please refer to the PDF document or feel free to contact us.
