Import Airflex 20vc1000 142832hc Equivalent Dalin — Buy in Bulk from Supplier in China

This Henan Dalin 20VC1000 equivalent clutch steps up to a 20-inch nominal drum diameter within the ventilated constriction clutch family, offering higher torque capacity for the most demanding inertia-load applications. The same torque-bar architecture applies: rotational force passes through dedicated bars rather than the pneumatic actuating tube, isolating the tube from shear and extending component life. A loose actuating tube sits inside a cast iron housing formed by a rim and two replaceable side plates, with aluminous brake shoes that wrap a cylindrical drum when pressurised. Release springs housed in the torque bar cavities return the shoes to neutral when air pressure exhausts. The design targets mining haul trucks, shovel drives, ball mill pinions, and marine winch systems where sustained slip and thermal load are routine operational conditions.

Material construction pairs cast iron housings with steel alloy structural elements and a friction-lined composite on the brake shoe contact surfaces. The 20VC1000 format increases radial envelope and friction area proportionally over smaller VC series members, permitting higher absolute heat dissipation per engagement. Ventilation geometry remains consistent with the series standard, drawing ambient air through the drum-shoe interface to stabilise lining temperature. Replaceable side plates permit field rebuild without discarding the entire housing, reducing life-cycle cost for remote installations. The torque bar system maintains constant engagement geometry regardless of lining wear, preserving torque output predictability through the service interval. Standard industry practice sizes the air supply for rapid fill to minimise engagement time lag in emergency-stop scenarios.

Primary procurement audiences include mining maintenance departments, heavy OEM drivetrain divisions, and aftermarket distributors serving construction and materials processing. The 20VC1000 suits retrofit of worn OEM Eaton Airflex units where original spares lead times or pricing are prohibitive. Importers should verify bore availability, maximum allowable runout, and whether the supplier provides installation tooling or torque sequence documentation. With zero recorded response rate on this listing, buyers may need to initiate contact through the supplier's physical address in Huixian, Henan, to negotiate terms and confirm production scheduling.

Henan Dalin Rubber And Telecommunications Apparatus Co., Ltd operates from 1 Jiushan Road, Huixian, Henan, 453600, China. The supplier's profile shows a harbor trust tier but records zero response activity, with no response rate and zero average response hours. This pattern suggests limited or inactive platform engagement, so buyers should plan for direct outreach via email, telephone, or physical correspondence to the Huixian address. The company lists equivalent clutches across the full VC size spectrum, indicating manufacturing or assembly capability for industrial power transmission components.

No information is provided about factory floor space, workforce size, annual turnover, ownership structure, or key accounts. Certification status, quality management systems, and export licensing are unstated. Buyers should not assume ISO registration, CE marking, or third-party accreditation without explicit documentation. A factory visit or video inspection may be warranted given the lack of digital responsiveness, particularly for first orders. The supplier's geographic location in central China implies inland logistics coordination for seaport export.
