• Sealed and Open Versions: Optional sealing protects against dust, debris, and moisture for extended service life.

• Wide Temperature Tolerance: Maintains performance in high-temperature operations typical in mining and industrial processes.

Manufacturing Process

1. Material Selection: High-quality alloy steel is selected for its hardness, toughness, and fatigue resistance.

2. Forging and Machining: Inner and outer rings and rollers are forged, heat-treated, and precision-machined to exact tolerances.

3. Heat Treatment: Bearings are hardened and tempered for maximum wear resistance and long service life.

4. Surface Finishing: Precision grinding of rollers and raceways ensures smooth operation and reduces vibration-induced wear.

5. Quality Control: Bearings undergo stringent testing for dimensional accuracy, load capacity, and vibration tolerance to ensure reliability in vibrating screens.
