Import Excavator Slewing Bearing/Ring — Buy in wholesale FOB from Supplier in China

The Excavator Slewing Bearing/ring from Luoyang Jiawei Bearing Manufacturing Co., Ltd. is a precision-engineered rotational bearing designed for heavy-duty excavator swing mechanisms. It features an integrated gear ring, inner and outer races, rolling elements, and sealing systems, with typical outer diameters ranging from 500 mm to 2,200 mm and bore sizes tailored to match excavator boom base interfaces. The bearing is manufactured using case-hardened alloy steel, with surface hardness values typically between HRC 58 and HRC 62, ensuring resistance to wear under cyclic loading.

The bearing structure includes a single or double row ball or roller configuration depending on load profile, with standard radial load capacities exceeding 800 kN and axial load capacities up to 450 kN. Typical sealing systems are multi-lip rubber with steel reinforcement, rated for IP67 ingress protection. Lubrication channels are integrated into the raceway design to support grease-fed maintenance cycles. These are standard features in industrial slewing rings used in excavators, cranes, and wind turbines, but this supplier’s units are machined to ISO 19977 tolerances for concentricity and raceway flatness.

These bearings are purchased by construction equipment manufacturers, heavy machinery repair shops, and OEM aftermarket distributors across Southeast Asia, the Middle East, and Latin America. Buyers typically require delivery in bulk quantities of 5 to 50 units per shipment, with packaging in wooden crates lined with moisture barrier film. Trade terms are commonly FOB Qingdao or CIF port of destination. Lead times average 30 to 45 days after order confirmation, subject to material availability and production scheduling.

Luoyang Jiawei Bearing Manufacturing Co., Ltd. is based in the Luoyang Science and Technology Zone, Henan Province, China, with a registered address in the industrial corridor near the Luoyang High-Tech Park. The supplier is classified as an imported tier vendor with harbor trust status, indicating verified export documentation and shipment history. The listing does not state years in operation, workforce size, or client names, nor does it claim ISO or CE certification as a guaranteed standard - only that the product meets international norms.

The company specializes in the production of slewing bearings for construction and mining equipment, with machining capabilities for large-diameter rings up to 2.5 meters. Production is conducted in-house using CNC gear cutters and heat treatment furnaces. There is no public information on third-party audits, R&D teams, or certifications beyond what is implied by product compliance. The supplier responds to inquiries with no recorded average response time, suggesting potential delays in communication.
