Osborn Load Rails® for Maximum Design Flexibility


Osborn Load Rails® are made of high-strength steel and machined to tight tolerances, then cut to length and drilled to customer specifications. Osborn Load Rails® are hardened on the rolling surface to 60-65 Rc. To determine a part number, specify the profile, replace “XXXX” with the track length dimension, and add the appropriate mounting option code (see chart). For example - to specify a 4" high V-track 28-1/2" long with a clearance hole for a cap screw, the part number is: LRTV-20284-1. Track length tolerance is ±1/16". Osborn Load Rails® offer allowable rail loadings up to 71,500 lbs (317450 N) per roller. Osborn Load Rails® also available in metric.
