Why Choose Our Rotating Bearing Solutions?

Factory-Direct Slewing Bearing Solutions – No Middleman Markup

All intermediate circulation links are eliminated. Quotations are directly based on the factory’s production costs and reasonable profit margins, saving customers 15%–30% of procurement costs. Whether it is bulk procurement of standard models or customized structural solutions, we offer factory-direct pricing at the lowest cost, passing on benefits to end-equipment manufacturers and project contractors.

Swift Response to Customization Requests, with Requirements Communicated Directly to Our Technical Department

Your requirements are communicated directly to our factory’s R&D and production teams without any intermediary relay. From structural selection, parameter optimization to non-standard customization, we can deliver a preliminary solution in as fast as 48 hours. Compared with supplies through intermediaries, our production lead time is reduced by over 20%, ensuring precise alignment with your project delivery schedules.

Full-Process Quality Control, 100% Traceable Product Quality

From raw material selection, forging and heat treatment, to precision machining and finished product inspection, every step is strictly controlled by the factory’s quality management system. A complete inspection report and production traceability file can be provided for each batch of products. We support customer factory supervision and random sampling inspections, eliminating the risk of inferior goods mixed in by intermediaries and ensuring that 100% of the delivered products meet technical standards.

Designing Advanced Engineering

Our rotating bearings come in a variety of structural configurations to meet your needs. You can choose from single-row four-point contact ball designs for standard uses, double-row reduced-diameter ball designs for installations with limited space, or three-row roller designs for the most load capacity. Cross-roller variants work best for applications that need high accuracy.

Very high quality materials

We use high-quality 42CrMo and 50Mn special alloy steel to make every bearing, which gives them a stronger base. The rolling parts are made of GCr15SiMn high-purity bearing steel, which makes them very resistant to wear and gives them a long life. Our imported nitrile rubber and fluororubber seals keep things clean and running smoothly.
