Stainless steel bearing for quick bearing replacement in extreme environments

drylin® W exchange bearing now available in stainless steel

igus® develops and tests materials for drylin® linear technology its in-house test laboratory. Always with the aim of long durability, low wear rates and a predictable service life. But the question: "What happens if a bearing has to be changed?"is gaining increasingly in importance.

  • Fast bearing change without disassembly
  • Reduced downtime
  • Complete re-use of all components
  • Simple spare parts management
This is exactly what the drylin® W exchange bearing now also enables for stainless steel linear guides or drive units. Installation sizes: 10, 16, 20 and 25. Open housing at the side, change bearing, close and you are finished. The system is "new" and ready to use again in a very short time. Whether special requirements due to chemicals, temperature or food - suitable liners are available for every environment. And with a weight of only 5g, spare parts handling is extremely simple.
