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: 0.5000 in Roller width: 0.3440 in Stud diameter: 0.1900 in Stud length: 0.5000 in Roller shape: Flat Roller material: Chrome Steel Bearing element: Needle Rollers Stud type: Standard Closure type: Sealed Head type: Hex Head Thread size: 11963 Radial dynamic load capacity: 620 lbs Radial static load capacity: 300 lbs Maximum rpm: 11500 rpm Lubrication hole location: Stud End Finish/coating: Black Oxide Series: Inch CAMROL (CF)
