Import Nu18/1600 Cylindrical Roller Bearing — Buy in wholesale FOB from Supplier in China

The NU18/1600 Cylindrical Roller Bearing offered by Hubei Parts Service Supply Co., Ltd. is a large single‑row roller bearing intended for high‑load industrial shafts. It possesses an inner diameter of 1600 mm, an outer diameter of 1950 mm and a width of 155 mm, all forged from high‑carbon chromium bearing steel (GCr15 / 100Cr6). The bearing follows the supplier’s custom specification for heavy‑duty service and is supplied with standard dimensional tolerances. These measurements place the bearing among the larger sizes commonly used in steel‑mill and mining equipment.

The GCr15 / 100Cr6 alloy is a widely accepted material for precision bearings, typically hardened to 60‑64 HRC after quenching and tempering. According to ISO 4920, the bearing conforms to the PN C3 clearance class, providing extra radial play for thermal growth. Typical lubrication for this class of bearing is mineral oil with a viscosity grade of ISO VG 68‑100, applied during assembly. The usual operating temperature span for such steel bearings ranges from - 20 °C up to 120 °C, which aligns with the supplier’s stated capabilities.

Common installations include steel‑mill rollers, large paper‑machine shafts and mining conveyor gearboxes where both high radial and moderate axial loads occur. Importers targeting OEM projects in the heavy‑manufacturing sector often request bulk shipments and may negotiate FOB or CIF terms, but exact conditions must be confirmed with the supplier. The supplier’s profile indicates a harbour verification tier but shows a 0 % response rate and no average response time, so communication reliability should be checked before finalising the order. Buyers should obtain confirmed lead times, minimum order quantities and payment arrangements as part of the quotation process.

Hubei Parts Service Supply Co., Ltd. is situated in Room 1402, Building 6, Yicheng, Hubei Province, China, postal code 441400. The firm is classified under the harbour verification tier, confirming that core business details have been validated by the platform. Its profile records a 0 % response rate and no average response time, indicating limited recent buyer engagement. The location lies within a recognised manufacturing hub for precision engineering components.

The supplier lists a portfolio of large‑size cylindrical roller bearings, including the NU18 series, and claims adherence to international quality benchmarks. No explicit certifications, production capacity figures or turnover data are provided in the listing. Prospective purchasers should therefore request material test certificates, hardness reports and any applicable ISO quality management documents directly from the supplier. Details such as minimum order quantity, lead time and payment terms are not disclosed and must be negotiated separately.
