What is the Sitrak Brake Air Chambers (27/27)

  • Sitrak Brake Air Chambers (27/27): Reliable Pressure Control for Safe Stopping
  • The Sitrak Brake Air Chambers (27/27) are precision-engineered components designed to deliver consistent braking power and responsive control in commercial vehicles, particularly those equipped with air brake systems. Modeled for heavy-duty applications, these chambers integrate a Diaphragm spring brake air chamber L=70 with robust mounting components like Pins, Cotter pins, and Flat washers, ensuring reliable performance under high-pressure conditions and extreme operating environments.
  • Core Design for Efficient Braking Force
  • The Diaphragm spring brake air chamber L=70 is the heart of the assembly, featuring a 70mm-stroke design that balances compactness with high-force output. Its dual-function design combines a service brake diaphragm and a spring parking brake, allowing seamless transition between normal braking and emergency/parking applications. The chamber’s diaphragm is constructed from heavy-duty rubber compounded to resist ozone, heat, and abrasion, while the spring mechanism uses high-tensile steel to maintain consistent pressure over thousands of cycles—critical for preventing brake fade and ensuring predictable stopping power.
  • Secure Mounting with Premium Fasteners
  • Pins and Cotter pins are essential for attaching the air chamber to the brake linkage, providing a stable pivot point for force transmission. The pins, made from heat-treated alloy steel, resist bending and wear, while the cotter pins—inserted through pre-drilled holes in the pin ends—lock them securely in place, preventing accidental disengagement during operation. This fail-safe design is vital for maintaining braking system integrity, especially in Bumpy road conditions (bumpy road conditions) where vibrations could otherwise compromise component alignment.
  • Flat washers complement the mounting system by distributing clamping force evenly across the chamber’s mounting flange. These washers, crafted from corrosion-resistant steel with a zinc-plated finish, reduce stress concentrations around bolt holes and protect the chamber body from direct metal-to-metal contact, extending the service life of both the washer and the air chamber. They are precision-sized to fit standard mounting bolts, ensuring a tight, vibration-resistant connection.
  • Performance in Harsh Environments
  • The 27/27 designation refers to the chamber’s dual diaphragm sizes (27 in³ for service brake, 27 in³ for spring brake), optimized for medium-to-heavy trucks and buses. The chamber’s housing is coated with a durable epoxy finish to resist rust and chemical exposure, while internal components are designed to minimize air leakage, ensuring consistent pressure retention and rapid response times. This makes the assembly ideal for long-haul trucks, construction vehicles, and buses operating in diverse climates, from high humidity to extreme cold.
  • Model Specificity: Clearly states “27/27” and “Diaphragm spring brake air chamber L=70” to target exact product searches and replacement parts queries.
  • Component Integration: Highlights “Pins,” “Cotter pin,” and “Flat washers” to enhance relevance for technical diagrams, maintenance guides, and parts lists.
  • Benefit-Driven Keywords: Emphasizes “reliable pressure control,” “high-force output,” and “corrosion-resistant,” addressing fleet managers’ priorities for safety, durability, and low maintenance.
  • In summary, the Sitrak Brake Air Chambers (27/27) are a testament to engineering excellence, combining a high-stroke diaphragm design with premium mounting components to deliver consistent, safe braking performance. Their robust construction and precise fastener system ensure they stand up to the rigors of heavy-duty use, making them an ideal choice for operators who demand reliability and peace of mind in their braking systems. Trust Sitrak to keep your fleet stopping power strong, mile after mile.
