1224 KM Bearing Structural Features & Performance Benefits
Double Row Design: The dual raceway configuration provides significantly enhanced rigidity compared to single row bearings, making it ideal for applications with substantial radial loads and moment forces.
Nylon Cage Construction: The polymer cage material offers excellent wear resistance and contributes to the bearing's high-speed capability of up to 4,000 rpm, while reducing friction and heat generation.
Optimized Geometry: With a protrusion of 1.271 mm and carefully calculated shoulder diameters (inner: 149mm, outer: 187.2mm), the bearing ensures proper load distribution and alignment in mounted applications.
Material Excellence: Manufactured from chrome steel for both rings and balls, the bearing delivers superior fatigue resistance and long service life under continuous operation.
