iglide® PRT Slewing Rings

Self-lubricating, maintenance-free

iglide® PRT slewing rings use self-lubricating, low-friction sliding elements in place of ball bearings. They represent a step forward in slewing ring bearing technology.

The sliding elements are made from an igus®-developed, low-cost, high-performance plastic called iglide® J, which is completely lubrication- and maintenance-free.

All the housing components are made from aluminum (except style 02, which has wear-resistant iglide® J4 inner rings) and all the surfaces parallel to the iglide® sliding elements are hard anodized with stainless-steel fasteners. A completely stainless-steel version is also available upon request.
