Description

SFB series symetric electro-hydraulic disc brakes

SFB Series Electro-hydraulic Disc Brakes are advanced products with high performance and multiple functions. They are maintenance-friendly due to advanced functions applied on them such as automatic shoe clearance equalization and wear-self-compensation. Various limit sensors can provide interlocking protection signal to main machinery PLC. They fit very well for decelerating and stop/braking large-scale modern machines such as loading and unloading machinery, lifting and transporting machinery, metallurgy equipment and mining equipment.

Main features

1. Interlocking shoes clearance equalization device and shoe auto-aligning device (patented technology), constantly equalize the clearance of brake shoes on both sides and no need to adjust, thus completely avoid one side of brake lining sticking to brake disc.
2. Self-lubricating bearings are equipped at main hinge points, which bring high efficiency of transmission, flexible action life and unnecessary to lubricate in the course of operation. The closing time is short (only 0.25-0.4s).
3. Stepless lining wear-self-compensation devices can make shoe clearance and brake torque be kept constant in the process of operation, thus be free from the trouble of frequent adjustment.
4. Torque adjustable built-in springs is set up with torque scale.
5. Brake linings are plug-in style, which are easy to replace. Brake linings of various materials such as powder metallurgy and semimetals (non-asbestos), which are suitable for different working conditions.
6. Equipped with our new thrusters: Swift reaction and having long life-span.
7. With hand release device, which can open the brake when under the powered-off condition.

Additional standard features

• Hand release sensor* can automatically send signals to main control to carry out the interlocking protection when brake applies the hand release.
• Release limit sensor* can indicate signals such as whether brake is properly released or provide interlocking protection.
• Lining wear limit sensor* can automatically indicate alarm signal or provide interlocking protection when wear of brake lining reached the limit.

• Ambient temperature: -20℃ ~ +50℃

• Relative humidity：≤90%
