51107 ISB thrust ball bearing

ISB 51107 Thrust Ball Bearing

The ISB 51107 is a single-direction thrust ball bearing engineered for precise handling of axial loads acting solely along the shaft axis. Part of the 511 series, it is characterized by its low cross-sectional height, making it an ideal solution for applications with limited mounting space. The separable design allows for independent installation of the shaft washer, housing washer, and ball-and-cage assembly, simplifying maintenance and lubrication.

Application

• Industrial gearboxes and vertical drive units.
• Regulating mechanisms and lead screws in machine tools.
• Pulley blocks and small-scale crane hooks.
• Conveyor systems and sorting equipment in production lines.
• Machine spindles requiring rigid axial support.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: 51107
• Type: Single-direction thrust ball bearing
• Series: 511 (Light series, low profile)
• Cage: Pressed steel
• Design: Separable components
