Import Airflex 24vc1000 142675hc Equivalent Dalin — Buy in Bulk from Supplier in China

The Airflex 24vc1000 142675hc equivalent from Henan Dalin Rubber And Telecommunications Apparatus Co., Ltd is a ventilated constriction clutch engineered for heavy-duty brake and clutch applications where sustained slippage and large inertia loads are present. This 24-inch diameter unit transmits torque through torque bars rather than sidewalls of the actuating tube, with the tube loose within a housing formed by a rim and two replaceable side plates. The model 24vc1000 is part of Dalin's VC series that spans sizes from 14vc1000 through 76vc1600, all sharing the same fundamental ventilated constriction architecture.

Construction centres on aluminium brake shoes with cavities that house the torque bars, which are held in position by side plates crossing through these cavities. Pressurising the air tube forces brake shoe engagement around a cylindrical drum, while release springs within the torque bar cavities provide automatic retraction when actuating pressure drops. Replaceable side plates extend service life, and the ventilated design dissipates heat generated during sustained slipping operations. Standard industry practice for equivalent clutches of this class specifies natural rubber or neoprene-based actuating tubes with fabric reinforcement, and aluminium alloy brake shoes compatible with cast iron or steel drums.

Primary applications include mining drives, oilfield machinery, marine winches, and heavy industrial equipment where controlled engagement and high thermal capacity are critical. Buyers are typically original equipment manufacturers, aftermarket service providers, and industrial maintenance divisions in sectors such as energy and materials processing. The 24vc1000 size suits medium-to-large drivetrains where the 24-inch drum diameter matches existing shaft configurations. Importers should confirm bore dimensions, air supply pressure requirements, and drum surface finish specifications directly with the supplier, as these determine retrofit compatibility with legacy Eaton Airflex installations.

Henan Dalin Rubber And Telecommunications Apparatus Co., Ltd maintains its registered address at 1 Jiushan Road, Huixian, Henan Province, 453600, China. The company holds a harbor trust tier, which indicates a verified business entity on the platform with basic credential confirmation. The response rate stands at 0.00 percent with average response hours recorded as zero, suggesting limited or no recent engagement through the platform messaging system. Prospective buyers should initiate direct contact to assess current communication channels and sales support availability.

The supplier specialises in rubber and telecommunications apparatus manufacturing, with this listing representing their venture into heavy industrial power transmission components through Eaton Airflex equivalent clutches. Their VC series covers sizes from 14vc1000 to 76vc1600, demonstrating range within the ventilated constriction clutch category. The source description provides mechanical detail about torque bar transmission and replaceable side plates, though it does not state manufacturing certifications, ISO accreditation, specific quality control protocols, or export experience. Buyers should request documentation of factory audits, material test certificates for brake shoe castings, and pressure testing records for actuating tubes.
