What are different cage types of Spherical Roller Bearings?
Spherical roller bearings are a type of rolling-element bearing designed to support high radial loads, moderate axial loads in both directions, and accommodate misalignment. They are commonly used in heavy-duty applications such as mining, construction, paper mills, and gearboxes.
1. MB (Machined Brass Cage)
- Material: Machined solid brass.
- Design: Two-piece inner guide cage with a central rib on the inner ring.
- Applications: Heavy-duty gearboxes: Used in industrial gear systems where high torque and continuous operation demand strong bearings with excellent heat and wear resistance.
2. MA (Machined Brass Cage – Inner Guided)
- Material: Solid brass.
- Design: One-piece machined brass cage guided on the inner ring.
- Applications: Pulp and paper processing equipment: Provide reliable operation in wet, steamy environments with continuous rotation and axial displacement of shafts.
3. CC (Stamped Steel Cage – Window Type)
- Material: Pressed steel.
- Design: Double-pronged, window-type cage with a symmetrical roller arrangement.
- Applications: Electric motors and generators: Offer high-speed stability and energy efficiency in compact motor designs where weight and size are critical
4. CA (Machined Brass Cage – Single Piece)
- Material: Solid brass.
- Design: Single-piece cage guided on the inner ring.
- Applications: Cement manufacturing plants: Used in rotary kilns and crushers where high temperatures and dust demand robust bearings with minimal failure risk.
5. E (Enhanced Design)
- Material: Stamped steel or brass.
- Design: Optimized internal geometry with a larger roller size.
- Applications: Bucket elevators: Enable smooth movement of bulk materials in vertical conveyors with significant axial and radial stresses.
6. E1 (Optimized E Series)
- Material: Stamped steel or reinforced cage options.
- Design: Advanced design from the “E” type with enhanced cage guidance and roller contact
- Applications: Continuous casting machines: Designed for extreme heat and continuous operation, ensuring long life under high radial forces.
