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 Roller width: 1.2500 in Stud diameter: 0.8750 in Stud length: 2.0000 in Roller shape: Flat Roller material: Chrome Steel Bearing element: Needle Rollers Stud type: Eccentric Closure type: Sealed Head type: Hex Head Hex size: 7/16 in Thread size: 41858 Radial dynamic load capacity: 8090 lbs Radial static load capacity: 8200 lbs Maximum rpm: 1400 rpm Lubrication hole location: Stud Side Eccentric stud diameter: 1.1870 in Finish/coating: Black Oxide Series: Inch CAMROL (CF)
