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 Bore diameter: 12 mm Roller width: 14 mm Roller shape: Flat Bearing element: Needle Rollers Closure type: Sealed Operating temperature range: -30 to +100 °C Radial dynamic load capacity: 2180 lbf Radial static load capacity: 3450 lbf Maximum rpm: 3900 RPM Lubrication hole location: Inner Ring Finish/coating: Uncoated
