CONTINUOUS SLAB CASTING SOLUTIONS-METALLURGICAL INDUSTRY BEARING SOLUTION-BEARING SULOTION FROM SIRKEN

Continuous Performance In Extreme Conditions

-SIRKEN Spherical roller bearings for continuous casters.-

·Engineered For High Static Load-carrying Capacity And Wear Resistance

Extreme temperatures, very high loads, and contamination are just some challenges that continuous casting lines face. Frequent and costly shutdowns for maintenance are inevitable as water, mold powder, and scale get into bearing housings.

If a bearing fails, all production must be stopped causing costly, unplanned downtime. At the same time, there is constant pressure to optimize production and cut costs per ton.

The performance of rotating equipment is a major factor in reaching steel plants' production and cost-reduction targets. The intense global competition in the steel industry makes smooth mill operations important. SIRKEN has tapped into our years of experience in the steel industry to develop the SIRKEN Spherical roller bearings for continuous casters.

The bearings are designed to provide excellent performance, wear resistance and cost efficiency in the extreme operating conditions.

Designed specifically for continuous casting applications, they provide a number of advantages, including:

• High static load-carrying capacity
• Good wear resistance
• Superior crack resistance
• Optimized for lubrication
• Fully interchangeable with standard spherical roller bearings

·Increased Bearing Life

The SIRKEN Spherical roller bearings for continuous casters are optimized to provide excellent performance in the continuous casting machine environment.

The bearing is designed for robust performance. Superior, high-grade steel helps to prevent unplanned downtime and catastrophic machinery failure. The cage design is optimized for low-speed rotation. The internal design of the bearing includes a larger grease reservoir that provides an average of 10% increase in grease capacity as well as enhanced oil flow for air-oil lubrication.

During its life cycle, the bearing design reduces grease consumption, making the SIRKEN Spherical roller bearings for continuous casters an environmentally friendly and cost effective choice. The sum of these improvements contribute to increased uptime and a lower total cost of ownership.
