Hydraulic Multi Disc Brake Equivalent to Mico Sahr 13-547-420

Product Description

Heavy-Duty Failsafe Braking Solution | 1:1 Interchangeable with MICO Series | SAE Modular Design

Winnect's SAHR (Spring Apply, Hydraulic Release) Multiple Disc Brakes are engineered as high-performance, drop-in replacements for the MICO® series. Designed for the most demanding mobile and industrial applications, these brakes ensure absolute safety by automatically engaging via heavy-duty internal springs whenever hydraulic pressure is lost.
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.

Specification

Engineering Features & Materials

Heavy-Duty Internal Springs: Precision-calibrated spring stacks provide consistent clamping force over millions of cycles without fatigue.
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.
