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.
