SWBTEC's Professional Manufacturing and Quality Commitment for Truck-Mounted Crane Slewing Bearings

Born for Excellence: SWBTEC's Professional Manufacturing and Quality Commitment for Truck-Mounted Crane Slewing Bearings

In the truck-mounted crane industry, the reliability and durability of every component directly impact the overall machine's operational efficiency and safety. As a specialized slewing bearing manufacturer, SWBTEC deeply understands this core requirement and is dedicated to providing high-performance, zero-compromise slewing bearing solutions for the world's leading truck-mounted crane manufacturers.

To date, we have successfully delivered over 2,000 sets of double-row ball slewing bearings to renowned crane manufacturers in Italy and Turkey, maintaining an exceptional "zero-complaint" record. This achievement stems from our precise control over critical quality points:

1. Core Materials and Structural Design:

We strictly select 42CrMo steel produced by major domestic manufacturers, subjected to quenching and tempering heat treatment. This ensures exceptional internal toughness and strength, capable of withstanding the impacts and heavy loads inherent in crane operations. The double-row ball slewing rings design delivers greater load capacity and higher torsional stiffness, guaranteeing smooth and precise equipment operation.

2. Precision Heat Treatment Process:

Addressing the frequent rotation and heavy load characteristics of truck-mounted cranes, we employ a selective heat treatment process where the raceway surface is hardened while the tooth section remains unhardened. This approach achieves exceptional hardness and wear resistance in the raceway while preserving the tooth section's superior toughness. This effectively prevents tooth breakage risks and significantly extends product lifespan under complex operating conditions.

3. Comprehensive Quality Monitoring:

SWBTEC maintains a rigorous quality management system—from incoming forging steel inspection and dimensional precision control during precision machining to 100% operational testing before final shipment. We focus not merely on meeting specifications but on ensuring every slewing bearing delivers long-lasting, stable, and quiet operation in your equipment.

SWBTEC is not just a supplier—we are your trusted partner. We look forward to powering your next-generation mobile cranes with our market-proven, reliable products, delivering a robust and dependable "rotating core".
