4th Axis Rotary Table, TJR Worm Gear Rotary Table AR(s)-210/250R/AR(s)-255R
4th axis rotary table, TJR Worm Gear Rotary Table AR(s)-210/250R/AR(s)-255R
Product Characteristics
- The worm shaft is made of case-hardened steel, featuring a specially designed and profile-corrected gear arrangement for higher efficiency, higher load carrying capacity, and precise accuracy.
- The worm gear is made of a special non-ferrous alloy with high anti-wearing properties.
- A unique profile on the worm gear ensures improved gear engagement between the worm gear and worm shaft while guaranteeing improved accuracy, lesser wear & tear, and uniform load distribution.
- This transmission mechanism is used in all standard 4th axis and 5th axis worm gear rotary tables.
