从China供应商批发进口6205 2rs/Zz/Open Bearing — FOB条款

The 6205 2RS/ZZ/OPEN is a deep groove ball bearing with a 25 mm bore, 52 mm outer diameter and 15 mm width, engineered for radial and axial load handling in compact assemblies. It is available in three configurations: 2RS with rubber seals for contamination resistance, ZZ with metal shields for light dust protection, and open for high-speed applications where minimal friction is critical. The bearing is manufactured from chrome steel GCr15 (AISI 52100), a material selected for its uniform hardness and fatigue resistance under dynamic loads.

Chrome steel GCr15 is the standard material for precision bearings, offering a typical hardness of 60-65 HRC and a density of 7.81 g/cm³. The 6205 series is a common size in the 6200 metric series, with a typical dynamic load rating of 14,000 N and static load rating of 7,800 N for open variants, though sealed or shielded versions may vary slightly due to friction from the closure. This series is widely used in electric motors, automotive transmissions, and industrial machinery where reliability and long service life are required.

Industrial buyers source this bearing for OEM applications in power transmission, agricultural equipment, and conveyor systems. It suits environments with moderate to high rotational speeds up to 15,000 RPM, depending on lubrication and load conditions. The bearing’s versatility makes it a standard choice for manufacturers seeking consistent performance in machinery with limited space for larger components.

Ningbo Renhe Machinery Bearing Co., Ltd. operates from Andong Town Industrial Zone in Cixi, Zhejiang Province, China. The company specializes in the production and supply of deep groove ball bearings, including the 6205 series, and positions itself as a provider for OEM and aftermarket demand in transmission and power transmission components. Its facility is equipped with automatic production lines and adheres to structured quality control processes, including 100% automated inspection for critical dimensions and performance parameters.

The supplier’s profile indicates a focus on precision bearings, with production capacity highlighted as 11 million sets per month. It holds an IATF 16949 certificate, which is a recognized quality management standard for the automotive industry, and emphasizes a 48-hour response commitment for inquiries and after-sales support. The company manages its raw material procurement and heat treatment in-house, which allows for tighter control over material consistency and bearing performance.
