Applications
The SBD-A Fail-Safe Disc Brake is designed for heavy-duty industrial equipment that requires reliable emergency stopping and operational safety. Typical applications include:
Cranes and hoists – Ensure safe lifting and load holding.
Mining winches and conveyors – Prevent accidental load movement during power or hydraulic failure.
Steel mills and metallurgical machinery – Maintain safe operation under high torque loads.
Port handling equipment – Secures containers and cargo in dynamic industrial environments.
Wind turbines – Provide fail-safe braking for pitch and yaw systems.
Quality Control & Compliance
Jiaozuo Xuda Machinery Equipment Co., Ltd. operates under the ISO9001:2015 Quality Management System. Every SBD-A series safety brake is produced under a fully traceable quality control process to ensure reliable performance in heavy-duty industrial applications.
Core Quality Control Points
Raw Material Inspection (IQC) – Key components such as disc springs and hydraulic cylinders are tested using chemical analysis and ultrasonic inspection.
Precision Machining Control – CNC machining ensures tight tolerances and consistent force distribution.
Critical Component Testing – Friction pads and hydraulic seals are tested for wear resistance, corrosion resistance, and pressure fatigue to ensure long-term reliability.
100% Functional & Load Testing – Each brake is tested to confirm rated braking force (72 kN to 315 kN) and safe hydraulic operation under real working conditions.
FAQ
Q: How does the fail-safe mechanism work?
A: The brake is spring-applied and hydraulically released. In case of power or hydraulic failure, the disc spring automatically engages the brake to stop the equipment safely.
Q: What are the available models and braking forces?
A: Models range from SBD100-A to SBD315-A, with braking forces from 72 kN up to 315 kN, suitable for brake disc diameters from Ø800 mm to Ø1800 mm.
Q: What certifications ensure product reliability?
A: All SBD-A brakes are manufactured under ISO9001 standards and hold Type Test Certificates, Explosion-Proof Certificates, and Mining Product Safety Mark Certificates.
Q: How is product quality verified before shipment?
A: Every brake undergoes 100% traceable inspection, including raw material testing, precision CNC machining, heat & surface treatment, assembly checks, and functional load testing.
Q: What kind of technical support is available?
A: Xuda provides pre-sales consultation, installation guidance, maintenance support, and rapid response for troubleshooting, ensuring smooth integration into industrial systems.
