61888 MA Bearing Product Overview & Core Advantages
The 61888 MA is a single row deep groove ball bearing engineered for high-performance applications demanding exceptional reliability and precision. This metric bearing is characterized by its robust construction and ability to accommodate high radial loads. Its open design and P6 tolerance class ensure superior running accuracy, making it an ideal choice for high-speed machinery and precision equipment where consistent performance is critical.
61888 MA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| MA | Indicates a brass cage (based on industry standard suffix interpretation for this bearing type), providing high strength and excellent guidance for the balls, suitable for high-speed operation. |
Key Specifications: The model designation is further defined by its core dimensions: 440 mm bore diameter, 540 mm outside diameter, and 46 mm width.
61888 MA Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove raceway geometry and high-quality chrome steel construction enable the bearing to support substantial radial dynamic load ratings of 57,326 lbf and radial static load ratings of 98,916 lbf.
- Precision & High-Speed Capability: Manufactured to a P6 tolerance class with a standard CN radial internal clearance, this bearing ensures precise shaft positioning and smooth operation. The combination of a stainless steel cage and optimized geometry contributes to a limiting speed of 1,800 rpm.
- Durability & Versatility: The open seal type allows for versatile lubrication options to suit specific application needs. Components made from chrome steel offer high wear resistance and a broad operating temperature range from -30°C to 120°C.
