Why Standard Bearings Fail in Vibrating Screens
Vibrating screens operate in one of the most demanding environments for rolling bearings. The main challenges include:
High-Frequency Vibrations & Impact Loads
Unlike steady rotational loads, vibrating screens subject bearings to constant, rapid shock loads. Standard bearings aren’t designed for this, leading to rapid fatigue and premature failure.
Extreme Temperatures
Continuous friction and heavy loads generate significant heat, which can degrade lubricants and reduce bearing steel hardness, diminishing load capacity.
Contamination Risks
Mining, quarrying, and aggregate processing environments are filled with abrasive dust and moisture. Without robust sealing, contaminants quickly degrade bearing performance.
WJY Bearing Solutions – Engineered for Extreme Conditions
Our vibrating screen bearings are not just components; they are precision-engineered solutions
Premium Materials & Heat Treatment
WJY spherical roller bearings are ideally suited for vibrating screen applications because they are manufactured from the finest quality steels using the highest quality standards.
- High-Quality Steel: We use vacuum-degassed bearing steel for superior purity and fatigue life.
- Advanced Heat Treatment: Our standard bearing material minimizes the impact of debris in harsh environments, like those found in aggregate industry.
Fully Machined Brass Cage
At the core of our design, WJY offers a fully machined brass cage. The benefits of the brass cage are numerous, including greater durability and cooler operation.
- Enhanced Durability: Brass cages withstand high accelerations and prevent cage failure under severe vibration.
- Cooler Operation: Brass’s thermal conductivity helps dissipate heat, extending bearing life.
Optimized Internal Design
- Increased Internal Clearance (C4/C5): To accommodate thermal expansion from high operating temperatures and prevent pre-loading, our bearings have larger radial internal clearance.
- Advanced Surface Finishing: New surface finishing techniques on the roller and raceway surfaces further enhance performance and longevity.
Superior Sealing Solutions
Contamination is a bearing’s worst enemy. We offer various sealing options tailored to your specific environment:
- LLU Seals (Non-Rubbing Labyrinth): Ideal for extreme high-speed and high-temperature applications, minimizing friction while keeping contaminants out.
- RS Seals (Rubber Seals): Provide excellent protection against moisture and fine dust in heavy-duty applications.
