Rotary Kiln Support Rollers (Trunnion Rollers)

Heavy-Duty Cast Steel Rollers Engineered for Maximum Kiln Uptime

The support rollers are the foundation of your rotary kiln's operation, bearing the immense weight of the entire rotating structure. The failure of a single trunnion roller can lead to catastrophic damage and plant-wide shutdowns, costing millions in lost production and repairs. To ensure continuous, reliable operation, you need support rollers engineered for maximum strength and durability.

Yile Machinery specializes in the large-scale casting and precision machining of rotary kiln support rollers. Using high-quality cast steel and a rigorous manufacturing process, we produce robust, reliable rollers that provide exceptional service life in the most demanding industrial environments.

Key Features & Benefits:

• Exceptional Load-Bearing Capacity: We use high-strength cast steel grades (e.g., ZG55, ZG42CrMo) and a proven sand casting process to produce massive, solid rollers capable of supporting the heaviest kilns and dryers.

• Optimized for Wear Resistance: Each roller undergoes a specialized heat treatment process (normalizing and tempering) to create a hardened surface that resists wear from the kiln tyre (riding ring), ensuring smooth rotation and a long operational lifespan.

• Precision Machining for Perfect Alignment: The roller body and shaft are precision machined to tight tolerances. This guarantees perfect alignment and contact with the kiln tyre, minimizing vibration, reducing wear on all components, and extending bearing life.

• Custom Manufactured for Your Kiln: We produce support roller assemblies to your exact specifications and technical drawings, ensuring a perfect, drop-in replacement for your existing equipment, whether for a cement kiln, lime kiln, or rotary dryer.

From Casting to Final Inspection: Our Commitment to Quality

A component this critical demands a flawless manufacturing process. Our quality control is integrated into every step.

1. Casting & Material Integrity: We utilize advanced casting simulation software to ensure a sound, defect-free casting. All rollers are made from certified cast steel for superior strength.

2. Specialized Heat Treatment: Our controlled heat treatment cycles refine the steel's grain structure, creating the optimal balance of surface hardness and core toughness.

3. Precision Machining: Using large-capacity vertical lathes and boring mills, we machine all critical surfaces for perfect geometry and a smooth finish.

4. Rigorous NDT Inspection: Every support roller undergoes comprehensive non-destructive testing (NDT), including ultrasonic testing (UT) and magnetic particle testing (MT), to guarantee it is free from any internal or surface defects before shipment.

Trust Yile Machinery to deliver a rotary kiln support roller that keeps your operations running smoothly and reliably.
