从China供应商批发进口Adapter Sleeve — FOB条款

Adapter sleeves from Shenzhen Ferris Trading Co., Ltd. are precision-engineered steel components that mount taper bore bearings onto cylindrical shafts, enabling secure bearing installation across varying shaft diameters. The standard material range covers carbon steel and stainless steel grades 304 and 316, with surface treatments available for corrosion resistance in demanding environments. These sleeves function as essential bearing installation hardware in industrial equipment manufacturing and aftermarket maintenance supply chains, with particular relevance to motors, pumps, conveyors, and heavy machinery applications where reliable locking action is critical.

The carbon steel variant offers cost-effective performance for standard industrial duties, while 304 stainless provides balanced corrosion resistance for food processing and chemical exposure settings, and 316 stainless delivers enhanced pitting resistance for marine and aggressive chemical environments. Locking mechanisms typically employ metric or imperial threads cut to ISO 2982 / DIN 981 standards, with nut and lock washer assemblies engaging the sleeve's external taper to draw the bearing inner ring firmly against the shaft seat. The split-body design allows radial compression during installation, creating a friction-lock that accommodates minor shaft tolerances and surface imperfections without compromising running accuracy.

OEMs in power transmission, pump manufacture, and materials handling represent the core buyer segments, alongside distributors serving plant maintenance and MRO channels. The supplier notes that pricing is negotiated according to model specification, so buyers should request dimensional confirmation including bore diameter, overall length, and thread size to match specific bearing series. Typical export packaging is standard for machined steel components, with rust-preventive oil and protective wrapping. Response rate data is not available, so direct enquiry is advised to confirm current lead times, minimum order quantities, and available surface treatment options.

Shenzhen Ferris Trading Co., Ltd. operates from Block 1, Oriental Pearl City, in Shenzhen's Longgang District, Guangdong Province, placing it within China's principal manufacturing and export corridor for industrial components. The company holds a harbor trust tier, indicating a verified business registration without additional assurance levels such as site inspection or transaction history disclosure. Response rate and average response time data are both recorded at zero, meaning prospective buyers should not expect rapid quotation turnaround and may need to follow up directly by phone or through alternative channels to secure technical and commercial information.

The listing presents Shenzhen Ferris Trading Co., Ltd. as a trading entity rather than a disclosed manufacturer, sourcing adapter sleeves in carbon and stainless steel grades for export across global OEM and aftermarket channels. No production capacity, employee count, revenue figures, or named client references are stated, and these should not be assumed. Buyers evaluating this supplier should request material mill certificates, dimensional inspection reports, and confirmation of thread accuracy compliance to ISO 2982 or equivalent standards. The absence of response metrics suggests that initial contact may require persistence, and buyers should clarify whether the supplier holds inventory or sources to order.
