Import Automotive Machinery Bearing — Buy in Bulk from Supplier in China

Zhejiang Jinfa Bearing Co., Ltd. supplies automotive machinery bearings from Ningbo, Zhejiang Province, engineered for engines, transmissions, and general automotive rotating assemblies. The bearings are offered in ball and roller configurations, with precision machining to manage radial and axial loads at sustained operational speeds. The supplier indicates industrial-grade material construction and references ISO and SGS certification compliance, though buyers should request current certificate copies directly. Load capacity, friction coefficient, and maximum RPM ratings are not stated in the source data and need supplier confirmation for matching to specific drivetrain or auxiliary systems.

Standard automotive bearing grades for this category typically employ through-hardened chromium steel (AISI 52100 or equivalent) for rings and rolling elements, with cage materials in pressed steel, brass, or engineered polymer depending on speed and temperature demands. Typical heat treatment achieves 58-64 HRC on raceways, with dimensional tolerances commonly held to ISO 492/199 class or tighter for precision spindle fits. Seal configurations range from single-lip contact seals to non-contact shields, with grease fill calibrated to operating temperature band. Noise and vibration grades (Z1V1, Z2V2, etc.) are standard classification tools in automotive supply chains, though Jinfa's specific grade offerings require direct inquiry.

Primary buyers include OEM automotive assembly plants, tier-one drivetrain suppliers, aftermarket distributors, and heavy equipment rebuilders sourcing for engine, gearbox, and pump applications. The bearings suit both mass-production vehicle programs and replacement part channels where consistent interchangeability matters. Packaging, MOQ, and lead time are not specified in the available data, buyers should confirm these with Zhejiang Jinfa Bearing Co., Ltd. directly. Incoterms such as FOB Ningbo or CIF destination are common for Zhejiang-origin bearing exports, but must be negotiated case by case.

Zhejiang Jinfa Bearing Co., Ltd. is located at B502 Qijiashan Street, Beilun District, Ningbo, Zhejiang Province, 315800, China. The supplier carries an imported tier designation on the platform with a harbor trust tier. The response rate is recorded at 0.00% with zero average response hours, which indicates no historical response data is available through the platform channel. Buyers should treat outreach timing as uncertain and plan follow-up accordingly, perhaps initiating contact through multiple methods if possible.

The company profile does not disclose year of establishment, factory size, headcount, annual revenue, or named client references.agh The listing positions Jinfa as a source for automotive machinery bearings with both ball and roller types, but does not enumerate specific series numbers (e.g. 6000, 6200, 30200, 30300) or OEM part cross-references. No MOQ, price band, or production capacity is stated. Verification of ISO and SGS certification scope, factory audit status, and sample availability should be requested directly from the supplier prior to commitment.
