Import Crossed Roller Bearing — Buy in Bulk from Supplier in China

The Crossed roller bearing from Luoyang Jiawei Bearing Manufacturing Co., Ltd. is manufactured in 42CrMo alloy steel, with model variants including 110.28.800, 111.28.800, 112.28.800, and 113.28.800. These bearings feature integrated internal and external gear teeth, enabling direct drive integration without additional coupling components. The design supports radial, axial, and moment loads simultaneously, making them suitable for applications requiring compact rigidity under combined stress conditions.

The material 42CrMo is a chromium-molybdenum alloy known for high hardenability and fatigue resistance, commonly used in precision bearings where dimensional stability under load is critical. Typical industry standards for such bearings include DIN 620-5 and ISO 3547-1 for dimensions and tolerances. The crossed roller arrangement, with rollers oriented at 90 degrees, provides uniform load distribution and minimizes elastic deformation, which is essential for maintaining positional accuracy in high-speed rotational systems.

These bearings are primarily purchased by manufacturers of CNC machine tools, robotic joints, and aerospace positioning systems where micron-level repeatability is required. Buyers typically require delivery in single-piece packaging with anti-rust coating and are advised to confirm bearing preload and clearance specifications before installation. Trade terms commonly offered include FOB Luoyang or CIF port of destination, with MOQs typically starting at 10 units per model, though custom batches may be arranged directly with the supplier.

Luoyang Jiawei Bearing Manufacturing Co., Ltd. is based in the Bearing Zone of Yiyang Industry Cluster District, Luoyang, China. The supplier is classified as an imported-tier manufacturer with harbor trust verification, indicating compliance with export documentation standards. The listing confirms active production of crossed roller bearings but provides no details on workforce size, annual output, or client list.

The company’s operational focus appears to be on precision bearing components for industrial automation, with manufacturing capabilities centered on gear-integrated roller bearing designs. There is no public information on certifications such as ISO or CE, nor are lead times or MOQs specified in the listing. Buyers are advised to request documentation directly to confirm material traceability and dimensional compliance.
