Thrust Ball Bearing

Design Principles: Adopt point contact design of high-precision steel balls and arc raceways, featuring small contact area and low friction coefficient to achieve efficient transmission of axial loads; single-row models achieve unidirectional axial positioning through a single row of steel balls, while double-row models can bear bidirectional axial loads through a double-row symmetrical steel ball design, no need for additional thrust bearings. The split structure facilitates installation, disassembly and maintenance without overall disassembly of related components; the cage guides the steel balls to move orderly, avoiding friction and collision between steel balls, improving operational smoothness and service life; the raceways are precision ground to reduce friction loss and temperature rise, adapting to medium-high speed precision operation. Performance Features: Core High Axial Load Capacity: Point contact design + high-precision steel balls, single-row models with maximum axial load up to 1500 KN, double-row models up to 2500 KN, adapting to the axial load requirements of medium-heavy equipment. Precision Positioning: P4-class ultra-precision rotational accuracy, axial runout ≤0.003 mm, meeting the micron-level positioning requirements of precision equipment. Compact Structure: Small size and light weight, high load-bearing density under the same installation space, adapting to equipment scenarios with limited space. Long Service Life & Stability: Surface hardening treatment of GCr15 material, precision polishing of steel balls (Ra≤0.02μm), fatigue life increased by 30% compared with conventional thrust bearings, adapting to long-term continuous operation. Low Friction & Low Noise: Point contact design + optimized cage, low operating friction coefficient (≤0.0015), noise ≤55 dB, adapting to silent scenarios. Customization Options: Supports non-standard size (shaft washer/housing washer size, thickness) customization, corrosion-resistant material (SUS440C) customization, unidirectional/bidirectional structure selection, special lubrication solutions for high/low temperature, and cage material customization (precision/silent dedicated).

Working Principle Ball Arrangement and Load Distribution: High-precision steel balls are evenly distributed along the annular raceways of the shaft washer and housing washer, guided by the cage for orderly movement. The point contact design between steel balls and raceways realizes uniform transmission of axial loads, avoiding local overload; double-row models bear bidirectional axial loads through a double-row symmetrical steel ball design, and the cage guides the two rows of steel balls to move independently without interference; the low friction coefficient design reduces operating energy consumption and improves equipment operating efficiency. Thermal Management and Sealing: - Thermal Management: Precision grinding of raceways and steel balls + low-friction cage design reduce frictional losses and effectively control operating temperature rise (typical temperature rise ≤10°C); combined with the thermal stability of dedicated grease or circulating oil, it ensures the thermal stability of equipment under medium-high speed and precision working conditions. Installation Adaptability: The shaft washer adopts an interference fit with the shaft (shaft h7), and the housing washer adopts a transition fit with the housing (hole H8), compatible with the assembly tolerance requirements of most industrial equipment; the split structure supports separate installation of the shaft washer, housing washer and steel ball assembly, adapting to complex assembly processes; double-row models can achieve bidirectional positioning without additional adjustments, simplifying the assembly process; the clearance can be precisely controlled through adjustment shims, ensuring accurate installation and stable operation.
