Product Description
Built with a fully enclosed modular housing, our brakes provide reliable parking and emergency braking in harsh environments—from underground mining to offshore marine operations. With high-strength ductile iron construction and heat-treated shafts, they offer superior torque capacity and a significantly longer service life than standard cast-iron alternatives.

Premium Friction Discs: High-coefficient friction material designed for stable torque even under high-heat or emergency stop conditions.
Fully Sealed Housing: An environmentally sealed design that isolates the friction stack from dust, water, and hydraulic contaminants—essential for mining and marine use.
Integrated Pilot Porting: Features standard dual-port configurations for ease of plumbing, with a built-in orifice option for smoother brake engagement.
