Where the 22336 Bearing Excels?

1. Metallurgy & Steel Production

Challenge: Bearings fail prematurely in rolling mills exposed to 120°C+ heat and heavy slab loads.
Solution: Our products use induction-hardened raceways and heat-stable cages to maintain precision under thermal stress.

2. Mining Equipment

Challenge: Crushers and conveyors face shock loads >500kN and abrasive dust.
Solution: Reinforced roller ends and optional labyrinth seals extend service life by 40% vs. standard bearings.

3. Port Machinery

Challenge: Crane slewing rings corrode in salty, humid environments.
Solution: Zinc-nickel coated products reduce rust-related downtime by 60%.

Quality Assurance: Built to Last

Every 22336 bearing undergoes:

1. Material Testing: Ultrasonic (UT) and magnetic particle (MT) inspection for forging defects.

2. Performance Validation: 200,000+ hour lifespan testing at 300 RPM simulated loads.

3. Noise & Vibration Checks: <35dB operation ensures compatibility with high-speed gearboxes.

Supply Chain Efficiency

Stock Availability: 1,000+ units ready for urgent repairs.
Custom Orders: Adjust inner ring taper (1:12 standard) or outer diameter (up to φ5000mm).
Global Logistics: Regional warehouses in EU, North America, and ASEAN support fast delivery.

Why Choose Us?

1. 30+ Years of Heavy-Load Expertise: We've served 1,200+ clients in metallurgy and mining since 1993.

2. End-to-End Customization: Modify material grades, seals, or dimensions without delaying production.

3. Full Compliance: ISO 9001, CE, and ROHS certifications included with every shipment.

4. Lifecycle Support: From bearing selection to IoT-driven predictive maintenance planning.
