⚙️Product Features:

100% Separable Interlocking Design: The shaft washer, housing washer, and ball assembly can be mounted independently, simplifying system installation and routine maintenance checks.
Superior Axial Load Rigidity: Specifically optimized raceway grooves guide the precision chrome steel balls perfectly, minimizing friction and energy loss under heavy axial thrust.
Exact Metric Standards: Precision-manufactured to 30mm (Bore) x 52mm (OD) x 16mm (Height) to guarantee a 100% perfect drop-in replacement for standard 51206 series bearings.
Ultra-Pure GCr15 Bearing Steel: Rings and rolling elements are forged from premium vacuum-degasified chrome steel, induction-hardened to achieve high fatigue limits and wear resistance.
Dual Brand Sourcing Flexibility: Increase your business competitiveness with our factory-direct RMO brand pricing, or request our trade network to procure authentic global premium brands.

⚙️Product Application:

Engineered for smooth rotation and high axial stability, the 51206 thrust ball bearing is extensively applied in:

Machine tool spindles, low-speed heavy-duty rotary tables, and index heads.
Industrial valve actuators, fluid control gates, and chemical mixing vessel shafts.
Heavy-duty screw jacks, mechanical lifts, and vertical hoist crane hooks.
Automotive steering gear systems and vehicle kingpin kingpins.
Marine propeller shaft thrust blocks, water pumps, and centrifuge gearboxes.

⚙️Precautions:

1. Keep clean	2. Use with caution	3. appropriate tool	4. Hot-loading	5. Be careful of rust
Dust will have a bad effect on the bearing, so keep the surrounding clean.	Strong impact during use can easily cause scratches and indentations.	Avoid replacing existing tools, and use appropriate tools.	Bearings are precision parts, so hot installation is recommended.	Sweat on your hands during operation will cause rust, so it is best to wear gloves.
