51206 Thrust Ball Bearing 30x47x15mm Single Direction | High Load Capacity, Low Noise, Long Service Life

The 51206 is a widely popular single-direction thrust ball bearing, specially designed to bear unidirectional pure axial thrust load. With standard size 30×52×16mm, it adopts high-quality GCr15 chrome steel and precision grinding process, delivering stable performance for vertical rotation and thrust support equipment.

• High axial load capacity: Features optimized raceway design and uniform force bearing, effectively withstands heavy axial pressure without deformation.
• Detachable 3-piece structure: Consists of shaft washer, housing washer and ball cage assembly, easy to install, disassemble and maintain.
• Durable & low noise: High-hardness steel body with wear resistance, matched with precision steel balls and steel cage, ensures smooth, low-vibration and quiet operation.
• Strong adaptability: Supports both grease and oil lubrication, works stably under long-time continuous operation, with long service life and low failure rate.

This 51206 thrust bearing is extensively used for mechanical parts that need vertical thrust support, including:

• Vertical pumps, fans and centrifuges
• Crane hooks, mechanical jacks and lifting equipment
• Speed reducers, gearboxes and transmission machinery
• Automotive clutch components and general industrial machinery
