Load Runners

Ağır Yük Serisi Idler Roller ve yüksek hassasiyet ve yüksek kapasiteye sahip seriler / Heavy-Duty Idler Rollers and Rails for High-Capacity Precision Load Handling.

Custom, short lead-time solutions and in-stock products for next-day delivery.

Superior Design Means Longer Life.

Longer Life Means Lower Costs.

Osborn Load Runners® are robust assemblies of carefully fabricated outer shells/treads and precision bearings fitted to high tolerance shafts. All Osborn Load Runners® match the tread, shaft and bearings into a cohesive, highly engineered unit used in dozens of industries and hundreds of applications.

Manufactured in the USA, Load Runners® feature heat-treated specialty steel, precision bearings, a maintenance-free lubrication and seal system, and a global network of sales support and application engineering expertise.

Osborn Load Runners® are designed and manufactured using exacting engineering principles with an emphasis on achieving:

• Better balance

• Increased bearing life

• Less tread/outer shell wear

• Reduced power consumption

• Smoother operation

• Quieter operation






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.
