THK INA Bolt Type Roller Bearing KR47-PP-A Bearing

Ball bearing track rollers are self retaining, single row or double row ball bearings with particularly thick outer rings. In addition to high radial forces, these bearings can also support axial forces in two directions. Yoke type track rollers are single or double row units installed on shafts or bolts. They include thick walled outer rings with irregular outer surfaces and needle roller and cage components or fully supplemented rolling element groups. Cam rollers are structurally similar to single row and double row supporting rollers, except that the raceway is formed by large cross-sectional roller screws with fixed threads and lubrication holes. The mature application areas of these products include cam mechanisms, guide rails, conveyor systems, and linear guidance systems.

• The radial bearing capacity is particularly high
• Capable of withstanding axial loads caused by deflection or tilting
• Long service life
• Easy to install
• Sealing increases reliability and comes with a supplementary lubrication structure
