Precision chains
For more than 80 years, IWIS has manufactured roller chain with the absolute highest precision and quality, and today more than 700 people work at the company's factory in Munich.
The Nexen RPS system for linear and rotary precision movements is based on two unique components:
• Gears with precision bearing rollers.
• Rack or gear segment with a unique tooth profile.
The gear drive can be delivered either prepared for a directly connected servo motor or with a suitable precision gear type Spinea for optimal precision.
The Nexen RPS system offers unique accuracy and repeatability - with absolutely no backlash.
With Nexen's linear system RPS, you can build infinitely long systems with the same accuracy as a card.
The racks are supplied in sections with an assembly tool to ensure perfect assembly.
Six different types of racks, one of which is stainless steel, and two different types of gears ensure that we can always find the right solution for every application.

Slewing bearing is a wire bearing that is fitted with an inner and outer ring. The advantage of this system is i.a. that the outer and inner ring can be made of materials other than steel – eg aluminum for light weight.
