61856 MA Bearing Product Overview & Core Advantages
The 61856 MA is a single row deep groove ball bearing engineered for high-performance applications requiring exceptional precision and reliability. This metric bearing is characterized by its ability to accommodate primarily radial loads, while also supporting moderate axial loads in both directions. Manufactured to a P6 tolerance class, it offers superior dimensional accuracy and running precision, making it an ideal choice for high-speed machinery and precision equipment. Its open design facilitates direct lubrication for optimized performance in specific operational environments.
61856 MA Bearing Model Code Explained, Specifications & Naming Convention
- 61856: Basic designation indicating a single row deep groove ball bearing with a 280mm bore and 350mm outside diameter.
- MA: This suffix indicates a specific brass cage design. The brass cage provides high strength and excellent guidance, contributing to the bearing's stability and suitability for high-speed operation.
61856 MA Bearing Structural Features & Performance Benefits
High Precision & Rigidity: Built to P6 tolerance with a standard CN radial internal clearance, this bearing ensures smooth, precise, and vibration-free operation, which is critical for maintaining the accuracy of the host machinery.
Robust Load Capacity: With a high dynamic load rating of 31,024 lbf and a static load rating of 44,962 lbf, it is designed to handle significant radial stresses over a long service life.
Optimized for High Speeds: The combination of the stainless steel cage (as per specification) and the precision-ground chrome steel components allows for a limiting speed of 2,800 rpm, making it a capable high-speed bearing.
Durable Material Construction: The rings and balls made from high-grade chrome steel offer excellent wear resistance and durability, ensuring consistent performance within a wide operating temperature range of -30°C to 120°C.
