| 20 | Outside Diameter: 150mm | Medium series dimension |
| Open Construction | No seals or shields | Suitable for controlled environments with external lubrication systems |
1220 Bearing Structural Features & Performance Benefits
Double Row Ball Design: The dual raceway configuration provides enhanced load distribution and superior rigidity compared to single row bearings, making it ideal for applications with significant radial forces.
Premium Material Construction: Manufactured from chrome steel rings and balls with a stainless steel cage, this bearing offers excellent wear resistance and corrosion protection, ensuring extended service life even in challenging operating conditions.
High-Speed Capability: With a limiting speed of 4,800 rpm, the optimized internal geometry and precision manufacturing enable reliable high-speed operation while maintaining dimensional stability.
Precision Engineering: Tight dimensional tolerances (bore: -0.02mm to 0, OD: -0.025mm to 0) ensure precise fitment and optimal performance in precision machinery applications.
