51300 Series Thrust Ball Bearing – High Load Capacity & Durability

51300 Series thrust ball bearings are precision bearings designed for high axial loads. They are suitable for industrial scenarios that need to withstand heavy loads in one direction and moderate speeds. High-quality steel and advanced heat treatment processes ensure long life, low friction and stable performance. They are the choice for heavy machinery, automotive transmission systems and industrial equipment.

Features:
Lightweight design: lightweight structure for easy installation and maintenance.
Grooved raceway: ensures smooth rolling of the ball during operation, reducing friction and wear.
Unidirectional axial load capacity: suitable for applications with unidirectional axial force.
High-speed performance: under oil lubrication conditions, a higher speed limit can be achieved.
Multiple size options: covering a variety of sizes to meet different application requirements.

Ultra-high load capacity
With a reinforced raceway design, the axial load capacity is increased by 20% compared to the standard model, suitable for high-pressure environments such as stamping machines and gearboxes.

Precision manufacturing process
High-precision Gr.10 steel balls + mirror-polished raceways, 35% lower friction coefficient, reduced energy consumption and temperature rise.

Long-term durability
Surface phosphating treatment + anti-rust coating, corrosion resistance meets ISO 9001 standards, and life is extended by 50% under harsh working conditions.

Flexible adaptability
A variety of sizes (51300-51400 series) and customized options (such as C3 clearance, sealing cover) are available to match different equipment requirements.

Application examples:
Sliding door system: used for axial positioning of doors to ensure smooth operation of doors.
Industrial machinery: used for axial support of rotating equipment to improve equipment stability and life.
Construction machinery: such as cranes, excavators, etc., used to support heavy axial forces.
Automotive parts: used for axial positioning of doors, sunroofs and other parts.

FAQ

Q1: Can 51300 bearings replace similar imported brands?
→ Yes! Our bearings have passed the SKF/FAG parameter test, with comparable performance and more competitive prices.

Q2: Is there a high temperature model?
→ High temperature steel (+200°C) or solid lubrication version available, please contact the technical team for details.

Q3: How to determine the bearing installation direction?
→ The bearing race is marked with an "↑" arrow to indicate the axial force direction, or refer to the installation guide provided with the goods.
