Self-lubricating polymer slew ring bearings
18 March 2010
Highly wear resistant, easy to install and completely maintenance-free
Plastic bearing expert igus has developed a range of innovative slewing bearings that use two self-lubricating, low friction polymer sliding elements in place of conventional ball bearings. As a cost-effective, low noise alternative, the igus PRT polymer slew ring bearing modules are also highly wear resistant, easy to install and completely maintenance-free, while at the same time are robust and have a very high load capacity. All housing parts are made of aluminium and use stainless steel screws. The polymer sliding pads in the PRT slewing rings are made of the high performance iglidur J material, which contains a solid lubricant, so it does not require additional lubrication. This material also offers a low coefficient of friction, as well as being resistant to chemical aggressors, featuring low moisture absorption and good vibration dampening properties. In addition, the counter-running surfaces of the iglidur J sliding pads are hard-anodized.
As explained by Matthew Aldridge of igus UK, the iglidur PRT slewing bearing modules are “rugged, corrosion-resistant units that are particularly well-suited in applications where high loads, extreme overturning torques, alternating ambient media or low to medium surface speeds are prevalent.”
Maintenance and lubrication-free, the iglidur PRT modules are ideal for OEMs looking for a ready-to-install solution, such as in semiconductor and cleanroom applications, assembly lines, wind turbines, production facilities and robots. The iglidur PRT slewing ring bearing system is available in a wide range of sizes, with outside diameters of 20, 30, 60, 100 200 and 300 mm.
