The T/single shaft brake torque is a specification indicating the braking force applied to a single axle. In the context of The part, this parameter defines the maximum torque that the brake chamber can generate on a single shaft. Our Brake air chamber is calibrated to deliver consistent torque output, ensuring balanced braking across all wheels.
The Pin roll is a hardened cylindrical pin that serves as a pivot point for the brake linkage. In The part assembly, the pin roll connects the push rod to the slack adjuster or brake lever. It is precision‑ground and heat‑treated to resist wear and shear forces, ensuring smooth and reliable actuation of The part.
The Flat washer is used under bolts and nuts in The part mounting hardware. It distributes the clamping load evenly, preventing surface damage and ensuring that The part remains securely attached to the axle bracket. The washer is zinc‑plated for corrosion resistance, contributing to the overall durability of the braking system.
The Cotter is a split pin that locks the castle nut on the pin roll or push rod. It prevents the nut from loosening due to vibration, ensuring that The part linkage remains intact. The cotter is a simple but critical safety component, and it must be replaced with a new one whenever The part is serviced.
This Brake air chamber is a diaphragm‑type spring brake actuator manufactured in Gongzhuling. It features a robust diaphragm and a powerful spring that provides both service and parking brake functions. The Type 11 Brake air chamber is designed for standard axle applications, delivering consistent braking force with a compact form factor.
The Type 12 Brake air chamber is another variant from the same manufacturer, offering slightly different stroke or mounting dimensions. This brake air chamber is optimized for specific axle configurations, ensuring that the braking force is correctly matched to the vehicle’s weight and performance requirements. Like all our brake air chamber units, it is tested for reliability and durability.
This Brake air chamber has a total length of 270 mm, making it suitable for applications where longer stroke is required. The extended stroke allows for greater brake pad or shoe travel, accommodating wear over time. This brake air chamber is a direct replacement for original equipment and is built to the same high standards as all our brake air chamber products.
With a compact length of 85 mm, this Brake air chamber is ideal for tight spaces where a shorter actuator is needed. Despite its smaller size, it delivers the same reliable braking force, thanks to its high‑efficiency diaphragm and spring design. This brake air chamber is commonly used on front axles or in retrofitting applications where space is limited.
