从China供应商批发进口6000 2rs/Zz/Open Bearing — FOB条款

The 6000 series deep groove ball bearing measures 10 mm inner diameter, 26 mm outer diameter, and 8 mm width, manufactured from high-carbon chromium steel (GCr15 / AISI 52100) with rings and balls hardened for wear resistance. Ningbo Renhe Machinery Bearing Co., Ltd. offers this bearing in three closure variants: open, 2RS double rubber sealed, and ZZ metal shielded, each suited to different contamination and speed environments. The P6 Z3V3 or P5 Z4V4 precision grades quoted indicate controlled tolerances and vibration levels for electric motor and general machinery duty. These are standard metric dimension bearings, interchangeable with ISO 15 dimensions, and form a staple reference in distributor and OEM procurement from Chinese manufacturers.

GCr15 bearing steel contains approximately 1.3-1.65% chromium and 0.95-1.25% carbon, a standard material grade for deep groove ball bearings offering a hardness of 60-65 HRC after heat treatment and good fatigue life under cyclic loads. The 2RS variant employs nitrile rubber seals with steel reinforcement on both sides, providing IP65-level dust and moisture protection but generating slightly more friction than open or ZZ configurations. ZZ shielded bearings use pressed steel shields with a small gap clearance, permitting higher rotational speeds while blocking coarse debris. Typical cage materials include stamped steel or polyamide, though the specific type should be confirmed with the supplier for temperature-critical applications.

Electric motor quality (EMQ) bearings in the 6000 size range serve fractional to small integral horsepower motors, pumps, gearboxes, and conveyor rollers where moderate radial loads and occasional light axial loads occur. The open configuration suits clean, lubricated environments with external oil or grease systems, while 2RS and ZZ variants target maintenance-free or sealed-for-life assemblies. Buyers should verify the exact precision grade, vibration class, and seal material compound before ordering, as these directly affect bearing life and noise performance. Tube packing and single-box packing are standard export packaging methods for this product category, with individual plastic bags and anti-corrosion paper inside cartons.

Ningbo Renhe Machinery Bearing Co., Ltd. is located at No.218, Weier Road, Andong Town Industrial Zone, Cixi, Zhejiang Province, China, 315327, placing it within the Cixi bearing manufacturing cluster, a region with extensive deep groove ball bearing production capacity. The company markets bearings under the RUWH brand name, which appears in its product literature as a domestic Chinese bearing brand. Its trust tier is listed as harbor, and both response rate and average response hours show 0.00 and 0 respectively, indicating no response data is currently recorded or the supplier has not engaged through platform messaging channels. The source description claims production capacity of 11 million sets per month, four heat treatment lines, automatic production lines, and IATF16949 certification, though buyers should independently verify current certificate validity and scope.

The supplier states it purchases and controls all raw materials, maintains stable raw material suppliers, and implements 5S management. It also advertises 100% fully automatic inspection, 48-hour delivery for stocked items, and a one-year warranty with free replacement. The company targets automotive, household appliance, pump, gearbox, electric motor, power tool, and conveyor applications, positioning itself as a volume supplier rather than a niche precision specialist. No information is provided about year of establishment, number of employees, annual revenue, or specific OEM client names. Buyers should request audited financials, factory inspection reports, and reference customers during due diligence, particularly given the absence of response metrics.
