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: Hex Head Radial dynamic load capacity: 2491 lbs Radial static load capacity: 3440 lbs Maximum rpm: 6400 rpm Lubrication hole location: Stud Side Finish/coating: Black Oxide Series: Metric CAMROL (MCF)
