Import Deep Grove Ball Bearing — Buy in Bulk from Supplier in China

Deep groove ball bearings from Harbin Jubang Precision Bearing Manufacture Co., Ltd are precision-engineered components designed to support combined radial and axial loads in rotating applications. The bearings are manufactured to DIN 625 and ISO 15 standards, with inner diameters ranging from 10mm to 100mm and outer diameters up to 180mm, depending on the series. Cage materials include stamped steel or nylon, selected based on operating speed and temperature requirements.

These bearings typically use chrome steel GCr15 for rings and balls, with standard radial clearances of C0 or C3. Surface finish on the raceways averages 0.2 micrometers Ra, and internal play is controlled within ±5 micrometers. Corrosion-resistant variants use stainless steel 440C for rings and balls, suitable for humid or washdown environments. Lubrication is supplied as grease with lithium-based thickener, rated for temperatures from -30°C to 120°C.

Applications include electric motors, gearboxes, conveyors, and agricultural machinery where consistent rotational performance is critical. Buyers in the automotive aftermarket, industrial automation, and light manufacturing sectors source these bearings for replacement and OEM use. Trade terms are FOB Harbin Port or CIF destination, with packaging in single-piece polybags inside cartons, stacked on pallets. MOQ is 100 pieces per size, and lead time is 15 to 25 days after payment confirmation.
