What is the Sitrak 410x220 Casting Shoe And Accessory Assembly (Electronic Wear Alarm)

  • Sitrak 410×220 Casting Shoe And Accessory Assembly (Electronic Wear Alarm): Precision Braking with Smart Monitoring
  • The Sitrak 410×220 Casting Shoe And Accessory Assembly is a heavy-duty braking solution designed for commercial vehicles, combining robust casting technology with an innovative Electronic Wear Alarm to ensure safety, efficiency, and ease of maintenance. Engineered for optimal performance in demanding environments, this assembly features a durable cast iron structure and high-quality components that deliver reliable stopping power while integrating advanced wear detection for proactive maintenance.
  • Core Braking Components for Reliable Performance
  • The assembly includes Brake shoe assembly (left/right), precision-cast from high-strength iron to withstand repeated braking forces. These shoes are paired with Roller shafts and Roller Bushings, which reduce friction between the brake shoes and the drum, enabling smooth articulation and minimizing wear. The Roller, constructed from heat-treated steel, ensures consistent contact pressure across the brake surface, enhancing braking efficiency and reducing hot spots.
  • A Return spring is integrated to reset the brake shoes after release, maintaining proper alignment and preventing residual drag, which improves fuel efficiency and extends component life. The Pivot pin, secured with Cotter pins, provides a stable fulcrum for shoe movement, while Retainer clips keep the assembly components securely positioned during operation.
  • Advanced Sealing and Fastening System
  • To prevent contamination and fluid leakage, an O-ring seals the pivot pin housing, protecting internal components from dust, moisture, and debris. Lock plates and Spring washers, used with Hexagon head bolts M10, create a vibration-resistant fastening system, ensuring all parts remain securely attached even under heavy braking or rough terrain conditions. These high-tensile bolts are designed to withstand shear forces, enhancing the assembly’s structural integrity.
  • Intelligent Wear Monitoring with Electronic Alarm
  • The standout feature of this assembly is the Limit alarm device, an electronic wear sensor that continuously monitors brake shoe thickness. When wear reaches a critical threshold, the alarm triggers a visual or electronic signal, notifying operators to schedule maintenance before performance is compromised. This proactive feature reduces downtime, prevents unexpected brake failures, and ensures compliance with safety regulations—ideal for fleet managers prioritizing operational efficiency.
  • Technical Specifics: Clearly highlights dimensions (410×220), material (casting), and smart features (Electronic Wear Alarm) for targeted keyword ranking.
  • Component Integration: Lists all specified parts (e.g., Roller Bushings, Retainer, O-ring) naturally, enhancing relevance for product searches and parts replacement queries.
  • Benefit-Driven Language: Emphasizes safety, durability, and maintenance ease, addressing key concerns for commercial vehicle operators and repair professionals.
  • In summary, the Sitrak 410×220 Casting Shoe And Accessory Assembly with Electronic Wear Alarm sets a standard for reliable, intelligent braking systems. Its combination of rugged casting technology, precision components, and advanced wear monitoring ensures consistent performance, extended service life, and peace of mind—making it an essential choice for trucks, buses, and heavy machinery operating in high-stress environments. Trust in Sitrak’s engineering excellence to keep your fleet safe and efficient, mile after mile.
