Overview
The W.C. Branham 4004-0714 is a pneumatic 38 Series caliper disc brake designed for precision braking control in industrial machinery. This single-acting brake features durable aluminum construction with hard-coat finish and Buna-N seals, sized for 5/32″ thick brake discs. Engineered for web tension control, emergency stopping, and load-holding applications across manufacturing, corrugated, and paper industries.
Key Features
- Single-acting pneumatic design with reliable spring return
- Aluminum body with hard-coated finish for extended service life
- Buna-N seals for consistent pressure retention and low maintenance
- Replaceable non-asbestos friction pads for safety compliance
- Sized for 5/32″ thick brake discs
- Compact 38 Series form factor fits standard mounting installations
Technical Specifications
The P38SA brake delivers predictable, repeatable braking torque across its operating range. Pneumatic operation ensures smooth engagement and release with minimal hysteresis. Buna-N seal material provides reliable fluid compatibility and temperature stability. The hard-anodized aluminum housing resists corrosion and maintains dimensional accuracy under continuous duty cycles.
Typical Applications
- Web tension control on paper and corrugated production lines
- Emergency stopping for rolls and reels
- Load holding on inclined conveyors and machinery
- Industrial presses and stamping equipment
- Material handling and positioning systems
