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: 32 mm Roller width: 14 mm Stud diameter: 12 mm Stud length: 25 mm Roller shape: Crowned Roller material: Chrome Steel Bearing element: Needle Rollers Stud type: Standard Closure type: Sealed Head type: Slotted Head Radial dynamic load capacity: 1542 lbs Radial static load capacity: 1810 lbs Maximum rpm: 9600 rpm Lubrication hole location: Stud Side, Stud End Finish/coating: Black Oxide Series: Metric CAMROL (MCF)
