The basic design of these products is essentially that of a conventional rolling bearing, except that they have a thick-walled outer ring. Stud type track rollers have a shaft stud at one end. In the majority of applications, the outer ring is subjected to circumferential load, i.e. the outer ring rotates while the inner ring or stud remains stationary. The thick walled outer ring prevents excessive deformation of the track roller and ensures that the rolling element set is uniformly loaded Specifications Roller diameter: 2.0000 in Bore diameter: 0.6250 in Roller width: 1.2500 in Roller shape: Flat Bearing element: Needle Rollers Overall width: 1.3125 in Closure type: Sealed Radial static load capacity: 17600 lbs Roller material: Chrome Steel Maximum rpm: 1400 rpm Lubrication hole location: Inner Ring Finish/coating: Black Oxide Series: Inch CAMROL (CYR)
