61880 MA Bearing Structural Features & Performance Benefits
- High Load Capacity: Engineered with a single row deep groove raceway, this bearing is optimized to support substantial radial dynamic loads (55528 lbf) and radial static loads (91048 lbf), ensuring reliable operation in high-stress environments.
- Precision & Accuracy: Manufactured to a P6 tolerance class with tight dimensional tolerances on the bore, outside diameter, and width, this bearing guarantees high running accuracy and precise shaft positioning, which is critical for precision machinery.
- Robust Construction & Durability: The use of chrome steel for the rings and balls provides high hardness and wear resistance. The stainless steel cage (M) ensures cage integrity and resistance to corrosion, contributing to a long service life.
- Standard Internal Clearance: The CN radial internal clearance is suitable for a wide range of standard operating conditions, providing a balance between fit and thermal expansion.
- High-Speed Capability: With a limiting speed of 1,900 rpm, the bearing is capable of operating efficiently in various high-speed applications.
61880 MA Bearing Typical Application Areas
- Heavy-Duty Industrial Gearboxes and power transmission systems.
- Large Electric Motors and generators requiring high radial load support.
- Material Handling Equipment such as conveyor pulleys and large rollers.
- Industrial Pumps and compressors.
- Construction and Mining Machinery where robust bearing performance is essential.
