PRT Slewing Rings
iglide® PRT slewing rings use self-lubricating, low-friction polymer sliding elements in
place of ball bearings. The sliding elements are made from an igus®-developed, lowcost, high-performance polymer 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® J sliding elements are hard anodized with stainless steel fasteners. A stainless
steel version is also available upon request.
Benefits:
• Off-the-shelf slewing rings ready to ship within 24 hours
• Custom hole patterns/machining available
• Downloadable CAD files at www.igus.com
• Lifetime calculation
• Custom options (e.g. gears, stainless versions)
• Technical support including on-site assistance within 36 hours
• Low cost

Required torque for centric load
Required torque for eccentric load
Alll load values assume the PRT is
assembled with socket head screws
(strength class 8.8) on the outside
pitch circle diameter. For the assembly
of the PRT the screws have to be
inserted to a minimum thread depth of
10mm.
