Air Brake Diaphragm
Hong Kong Metro Bearing And Automotive Limited offers air brake diaphragms manufactured from an elastomer compound with fabric reinforcement, using an EPDM/NBR blend. These diaphragms are critical components in commercial vehicle air brake systems, designed to withstand repeated high-pressure actuation in trucks, trailers, and buses. The supplier provides multiple sizes, including 9", 12", 16", 5", 5.5", and 16"L variants, catering to a broad selection of braking system configurations.
The diaphragms are engineered for consistent flex life and durability, with the fabric reinforcement enhancing resistance to tearing and fatigue. Industry-standard diaphragms for air brake systems typically exhibit a tensile strength of 15 to 25 MPa and an elongation at break of 300% to 500%, depending on the elastomer blend. These components are widely used in OEM and aftermarket markets, particularly for fleet maintenance and commercial transport logistics.
Primary buyers include automotive parts distributors, fleet operators, and maintenance providers in the heavy-duty vehicle sector. The diaphragms are sourced from automotive manufacturing hubs and are essential for ensuring reliable braking performance. Buyers should confirm the exact elastomer composition and fabric reinforcement specifications, as these directly impact the diaphragm’s service life and compatibility with their braking systems.

Sourcing Air Brake Diaphragm from Hong Kong Metro Bearing And Automotive Limited - Hong Kong Import Guide
Before placing an order, verify the diaphragm’s elastomer blend, fabric reinforcement, and size compatibility with your brake chamber. Request material test reports and certifications to confirm compliance with industry standards such as SAE J840 or ISO 6605. Cross-check the tensile strength and elongation properties to ensure they meet your operational demands.
Clarify the Incoterms, as these will determine your responsibility for shipping, insurance, and import duties. Confirm the lead time for production and delivery, particularly for bulk orders, and agree on payment terms such as T/T or L/C. Ensure the packaging is suitable for international shipping to prevent damage during transit.
Upon receipt, conduct a visual and dimensional inspection of the diaphragms to verify they meet your specifications. Request documentation such as material certificates, test reports, and compliance statements. If third-party inspection is required, arrange it prior to shipment to avoid delays or quality disputes.
