UltraLife-Disc

The UltraLife-Disc Caracteristics

  • Full Immersion E-coating
    Full immersion electro-deposition coating inside and out and an exclusive powder coating finish for the most durable corrosion protection in the industry.

  • NEW TSE All-n-One™
    New TSE all-n-one self-guided recessed pressure plate. Diaphragms are factory sealed to pressure plate. Assures proper alignment to extend life of pressure plate, diaphragm and power spring.

  • Unique Port Adapter
    UL-Disc features a unique composite port adapter which reduces profile size and allows for easy air connection.

  • Patented Bushing Assembly
    Patented bushing assembly provides center seal that traps lubricant for extended service, reducing center section leaks and brake drag.

  • Premium Diaphragm
    Premium diaphragms feature high quality contaminant resistant rubber reinforced with nylon fabric tested well beyond the toughest industry specifications.

  • All Steel Design
    All steel design provides durable, air tight center section that virtually eliminates leaks, structural failures and prevents galvanic corrosion.

  • High Vibration Base
    TSE designed High Vibration "HV" mounting base reduces vibration for longer life standard on UltraLife products.

  • Innovative Design
    UL-Disc features a 100% steel inverted spring bottom housing that reduces both spring coil-to-coil contact and spring coil-to-spring housing contact. The all-steel design provides a durable, air-tight center section that virtually eliminates leaks and structural failures, while the recessed pressure plate allows for a shorter and more compact chamber.

  • Premium Quality
    TSE is an ISO 9001 and KBA certified company. As an OEM premium direct fit and aftermarket replacement, UL-Disc is the premium brake for your heavy-duty disc brake trucking application.

  • Tough Main Spring
    UltraLife main spring adds a proprietary base coating in addition to TSE's multi-stage coating system for the ultimate in corrosion protection. Tested to double SAE standards, UL-Disc’s main spring actually exceeds SAE dry cycle testing requirements in a slurry environment.

  • Complete In-House Testing
    UL-Disc brake actuators undergo rigorous in-house testing in TSE’s comprehensive testing lab. Tests include variable pressure cycle testing, vibration testing, hot cell cycle testing, salt spray testing, cold cell leak/operational testing and slurry testing

  • Superior Corrosion Resistance
    With TSE’s exclusive in-house process, all parts of the UL-Disc actuator receive a multi-stage pre-treatment prior to e-coat and an extra layer of polyester powder coating protection.
