Product Details
The BSFH500 is a spring-applied, hydraulically released safety brake with a maximum tightening force of 200,000N.
The bearings and shafts are equipped with floating and self-aligning operation, which makes the brake particularly suitable for axial movement of the discs of the drive system.
The compact design is ideal for applications where space is limited.

Mechanical brake release and brake pad wear indicator switch
Equipped with brake release and brake pad wear sensing sensors (digital or analog output)
Sintered metal for high speeds or high temperature applications Organic asbestos-free brake pads
This series of brakes is suitable for damp, dusty and highly corrosive environments
Hydraulic direct-acting brakes
Hydraulic control of the brake meets a variety of braking functions
Automatic brake pad wear adjustment and brake clearance adjustment
Positioning system - prevents unnecessary brake pad wear if the brake axis is not 100% horizontal (for BSFH500MS).
Small clearance, fewer moving parts, shorter response time, faster braking speeds
Easy adjustment reduces maintenance costs
Large brake pad contact area
--Lower temperature of brake pads and discs
--Extended brake pad service life
Two sets of brake disc springs to reduce braking force loss
--Improve the safety of brake
Easy maintenance with fewer moving parts
-Reducing maintenance costs
Easy brake pad replacement due to removable brake pads
-Reducing maintenance costs
Easy to install - only 6 M36 bolts are used
Installation of the brake pads is based on spring retraction, which ensures that the brake pads always return to their original position, thus avoiding wear of the brake pads.

Explanation of BSFH 500 model number
BS is for brake system
F is for fail, safe, spring brake, hydraulic release
H is the brake type
500 = Clamping force
507=70,000 N
Calculation
1. All data are based on a clearance of 1mm on one side and a maximum clearance of 1mm on
one side.
2. The braking force is based on the minimum tightening force and the theoretical friction coefficient μ=0.4, and both sides are in contact.
3. The loss of tightening force caused by every 1mm of piston movement is 1mm of wear on one side of the brake pad.
F₈=Fc×2×μ
M. =1/2×a×F. × (D . -0.22)
M₈ = Braking torque (Nm)
a is the number of brakes acting on the brake disk
F. is the braking force reference braking torque table (N)
D. is the outer diameter of the brake disk (m)
0.22= Width of brake pad (m)
