Product Description

51108 Thrust Bearing Single Direction Ball Thrust Bearing Medium High Speed Adaptable

51108 Single-Directional Thrust Ball Bearing Medium-High Speed Adaptable
The 51108 bearing is a single-direction thrust ball bearing, primarily used to bear unidirectional axial loads, and is suitable for mechanical scenarios requiring high axial support precision.

Core Parameters

Bore diameter: 40mm
Outer diameter: 60mm
Width: 13mm
Dynamic rated load: 25.5kN
Static rated load: 63kN
Limiting speed: 7000r/min (data from SKF)
Structural features: Separable design (shaft washer, housing washer, and ball assembly are independent), facilitating installation and maintenance.

Typical Application Scenarios

Engineering Machinery: Axial support for hydraulic jacks and crane hooks, bearing vertical unidirectional loads.
Machine Tools & Industrial Equipment: Axial positioning of spindles in vertical machining centers and support for centrifuge drums, ensuring stability during high-speed operation.
Automotive & Transmission Systems: Axial limiting of automatic transmissions and clutch release bearings, adapting to frequent start-stop axial loads.
High-Temperature Environments: Stainless steel variants (e.g., SIAIF 440 stainless steel) can be used in high-temperature scenarios such as steel mill metallurgy and kilns.
General Machinery: Axial support for vacuum pumps and reducers, especially suitable for equipment requiring frequent disassembly and maintenance.

Technical Advantages and Precautions

Performance Features

High-Speed Adaptability: Data shows the limiting speed reaches 7000r/min; combined with precision-machined raceways, it can meet medium-speed requirements.
Impact Resistance: Bearing steel materials (e.g., HRB, SKF) have high hardness and wear resistance, suitable for heavy-load conditions.
Separable Design: Shaft washers and housing washers can be installed separately during installation, reducing requirements for the assembly precision of the shaft system.

Usage Recommendations

Minimum Load Requirement: Under high-speed or variable load conditions, ensure the bearing bears a minimum load of at least 2.32kN (data from SKF) to avoid slip damage between balls and raceways.

Installation Specifications: Avoid direct impact on the bearing; use special sleeves or press machines to apply force evenly. Check the fit precision of the shaft and housing bore before installation; the mating surfaces must be clean and coated with grease.
Lubrication Maintenance: Lithium-based grease is recommended; silicone-based grease can be used in high-temperature environments. Regularly check the grease condition.
