Designed with a compact and robust structure, the SE Series offers a high braking force within a lightweight profile, making it ideal for diverse applications such as cranes, conveyor systems, mining equipment, port machinery, construction machinery, wind turbines, and textile machinery. With braking capacities ranging from 560N (560SE) to an impressive 35,000N (ST1SE safety brake), these brakes ensure your equipment operates smoothly under various load conditions.
Key Performance Highlights
Rapid Response: With response times as short as 0.15 seconds for models like ST1SE, the SE Series guarantees swift engagement during emergency or high-frequency braking scenarios.
Precise Dimensions: External sizes vary from 190mm to 1220mm, with minimal runout (±0.2mm) on the brake disc face, ensuring stable and consistent operation.
Power Efficiency: Operating at low power consumption—only 7W for the 560SE model during maintenance—the brakes reduce energy costs without compromising performance.
Versatile Drive Options: Available with electromagnetic, hydraulic, or pneumatic release mechanisms, tailored to your specific operational needs. For example, the electromagnetic models operate on dedicated power supplies (230V/400V, 50-60Hz) with quick activation times, while hydraulic and pneumatic variants are suited for heavy-duty or high-reliability applications.
Enhanced Maintenance and Safety Features:
The SE Series incorporates automatic brake pad wear compensation, extending service intervals and maintaining consistent braking torque. Optional accessories such as wear indicators, brake status displays, and manual release controls provide real-time monitoring and simplified maintenance, minimizing downtime and safeguarding your personnel and assets.
