BSFG400

Product Classification:

Product Details

The BSFG400 is a spring applied, hydraulically released safety brake with a maximum tightening force of 120,000N.

Options

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 speed 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

Bidirectional disc spring brake

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

Leakage ports prevent hydraulic fluid from leaking and fouling the brake discs for high brake safety.

Explanation of the model number BSFG 400

BS is for brake system

F is for fail, safe, spring brake, hydraulic release

G is the brake type

400 = Clamping force

Calculation

1. All data are based on a clearance of 1mm on one side and a maximum clearance of 3mm on one side.

2. Braking force is based on the minimum clamping force and the theoretical coefficient of friction μ = 0.4, both sides in contact.

3. The loss of tightening force caused by each 1mm movement of the piston is 1mm of wear on one side of the brake pad.

F₈ = Fc×2×μ

M₈=1/2×a×F ₈×(Do-0.22)

M₈ = braking torque (Nm)

a is the number of brakes acting on the brake disk

Fa is the braking force Refers to braking torque table (N)

D. is the outer diameter of the brake disk (m)

0.22= Width of brake pad (m)
