Import Ball Bearing — Buy in wholesale FOB from Supplier in Global Markets

U&P Bearings Manufacturing Co., Ltd. supplies deep groove radial ball bearings in chrome steel (GCr15 / AISI 52100) or stainless steel 440C, configured for industrial machinery, automotive assemblies, and power transmission systems. The bearings are manufactured to ISO and ABEC precision standards, with metric and inch sizing available and options for steel cages and rubber seals. These specifications suit both original equipment procurement and aftermarket replacement programmes where dimensional consistency and fatigue resistance are critical.

The GCr15 chrome steel variant, equivalent to AISI 52100, is an alloyed through-hardened steel offering a typical hardness of 60-65 HRC after heat treatment, with standard inclusion cleanliness ratings per ASTM A295. Stainless steel 440C provides improved corrosion resistance in humid or mildly corrosive environments, though at a slight reduction in load capacity compared with the chrome steel equivalent. Deep groove geometry supports combined radial and axial loads, with typical internal clearance groups ranging from C2 to C5 depending on fit and thermal conditions. Seal configurations include single or double rubber contact seals (2RS), metal shields (ZZ), or open variants for grease relubrication access.

Buyers span OEMs in automotive drivetrain manufacturing, industrial gearbox rebuilders, and power transmission distributors serving maintenance, repair, and operations channels. The bearings are commonly specified for electric motor shafts, conveyor pulleys, pump assemblies, and agricultural implement spindles. For procurement, confirm the required precision grade (ABEC-1 to ABEC-7), cage material, and seal type with the supplier, as these determine suitability for high-speed or contaminated environments. U&P Bearings Manufacturing Co., Ltd. holds a harbor trust tier with a current 0.00 response rate, so direct enquiry is essential to confirm availability, minimum order quantities, and current lead times.

U&P Bearings Manufacturing Co., Ltd. is a ball bearing supplier based in China, though the supplier's registered address was not provided in available data. The company carries a harbor trust tier designation on the platform, indicating a foundational verification level rather than an advanced or premium tier. Notably, the supplier's response rate is recorded at 0.00 with an average response time of zero hours, which suggests either a newly listed profile or inactive communication channels. Buyers should treat direct contact as essential rather than optional when engaging with this supplier.

The listing positions U&P Bearings Manufacturing Co., Ltd. as a manufacturer rather than a trading intermediary, with emphasis on precision engineering to ISO and ABEC standards. No verified factory audit, export licence number, or years in operation is stated in the profile. The supplier markets metric and inch size bearings with material options in chrome steel and stainless steel, targeting OEM and replacement markets globally. Buyers are advised to request a company profile, quality system certification, and reference samples before committing to volume orders, given the limited transactional history visible on the platform.
