Excellent for precision handling of heavy loads in tough environments Combine the high capacity of Load Runners idler-rollers with high-strength steel Load Rails, cut to length and drilled to customer requests. Every piece is designed to perform Idler-roller treads are machined from high-alloy steel, then case hardened to HRC 55-60 for a wear-resistant outer shell and tough inner core. Precision tapered roller bearings (larger sizes) and deep-groove ball bearings withstand heavy radial and thrust loads, as well as high speeds. Idler-rollers are tightly sealed and lubricated for life to withstand dirt, sand and moisture. High-shear-strength studs (stud style) are manufactured with hex socket for easy installation. Thru-shafts (yoke style) eliminate the need for customer fabrication. Tapered bearings for superior thrust load tolerance High radial and simultaneous high thrust capacity Completely sealed to keep out harmful contaminants Lubricated for life Sizes from 26 mm to 250 mm, resp. 290 mm Metric and Inch ranges available High operations speeds Large choice in V-Grooved Style idler-rollers Maintenance-free at -34°C to +107°C Modifications include high-temperature grease and seal, non-metallic tread, solid lubricant, provision for relubrication and others, see Special Solutions Customized Osborn load rails made of high-strength steel are straight and twist-free, with hardened contact surfaces and extremely loadable. To support lighter loads that don’t require the heavy-duty performance of Osborn’s Load Runners idler-rollers we recommend the use of Cam Runner.
