Import Deep Groove Ball Bearings — Buy in Bulk from Supplier in China

Deep groove ball bearings from Xian Weinuo Machinery And Equipment Co., Ltd. are precision-engineered components designed to handle combined radial and axial loads in rotating machinery. The bearings are manufactured to standard dimensions per ISO 15 and DIN 625, with bore diameters ranging from 10 mm to 120 mm, outer diameters up to 260 mm, and widths between 12 mm and 62 mm. These dimensions align with common industrial classifications and are available in both open and shielded configurations.

The raceways and balls are typically made from high-carbon chromium steel, such as AISI 52100 or equivalent, with hardness values of 58-62 HRC after heat treatment. Internal clearance is usually C0 or C3, depending on application demands. While the listing does not specify exact material certifications, the steel composition and heat treatment follow widely accepted industry norms for ball bearings used in motors and gearboxes. Surface finish and ball roundness are critical to reducing friction and extending service life under continuous operation.

These bearings are commonly sourced by manufacturers of electric motors, automotive alternators, conveyor systems, and industrial pumps. Buyers typically require them for applications where low noise, moderate speeds, and reliable performance are priorities. Packaging is usually in single-piece plastic tubes or bulk cartons, with each carton holding 10 to 50 units depending on size. Trade terms such as FOB and CIF are available, and payment methods include T/T and L/C. Buyers should confirm exact bearing codes and clearance classes before ordering.
