Osborn Load Rails are hardened on the rolling surface to 60-65 Rc and offer rail loadings of up to 71,500 lbs (317450 N) per roller.
To specify a part number, replace the "XXXX" with the track length dimension as follows: the first 3 X's are length in whole inches up to 144", and the last X is fractional length in 1/8 inches i.e. 6 = 3/4". Then attach the mounting option code. 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.
