Stud type track rollers are similar in their construction to single and double row yoke type track rollers, except that the raceway is formed by a heavy-section roller stud with a fixing thread and lubrication hole. Due to the thick-walled outer ring with profiled outside surface and the rolling element set, they can support high radial loads as well as axial loads arising from slight misalignment and skewed running; they are suitable for applications such as cam gears, bed ways and conveying equipment Specifications Roller diameter: 80 mm Roller width: 35 mm Stud diameter: 30 mm Stud length: 63 mm Roller shape: Crowned Roller material: Steel Bearing element: Needle Rollers Closure type: Sealed Head type: Hex Head Hex size: 8 mm Thread size: M30 x 1.5 mm Operating temperature range: Maximum of +280 °F Overall length: 100 mm Radial dynamic load capacity: 36.9 kN Radial static load capacity: 72 kN Maximum rpm: 1800 rpm Lubrication hole location: Head, Stud End Finish/coating: Uncoated Standards met: ANSI/ABMA Standard 18.1, ISO 7063 Series: KR
