1224 M Bearing Product Overview & Core Advantages
The 1224 M is a double row deep groove ball bearing designed for applications requiring high radial load capacity and compact design. Manufactured to metric standards, this bearing features an open construction without seals, allowing for optimal lubrication access and heat dissipation. Its double row ball complement provides enhanced rigidity and load distribution compared to single row designs, making it suitable for machinery where space constraints and high radial loads are primary concerns. The bearing comes pre-lubricated and is capable of operating within a broad temperature range, ensuring reliable performance in demanding industrial environments.
1224 M Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1224 | Standard bearing designation indicating bore diameter (120mm) and dimensional series |
| M | Nylon cage (polyamide) for reduced weight, lower friction, and improved high-speed performance |
1224 M Bearing Structural Features & Performance Benefits
Enhanced Load Capacity: The double row ball construction significantly increases radial load carrying capacity compared to single row bearings, with a dynamic load rating of 26,775 lbf and static load rating of 11,925 lbf. This makes the bearing suitable for applications with substantial radial forces.
High-Speed Capability: The nylon cage (M designation) reduces rotational mass and provides excellent guidance for the balls, contributing to the bearing's limiting speed of 4,000 rpm. The open design facilitates efficient lubrication distribution for optimal high-speed performance.
Precision Dimensions: Manufactured with tight tolerances including bore diameter tolerance of -0.02mm to 0 and outside diameter tolerance of -0.03mm to 0, ensuring precise fit and alignment in demanding applications.
Material Quality: Constructed from chrome steel for both rings and balls, providing excellent hardness, wear resistance, and durability under heavy loads and extended service life.
