BSAB 90 DUAL-action

Product catalog summary
Specification
The document provides technical specifications for the BSAB 90 DUAL-action disc brake. Key parameters include:
  • Braking torque (MB) calculation formula: MB = a · FB · (DO - 0.102) / 2, where:
    • a: Number of brakes acting on the disc
    • FB: Braking force
    • DO: Brake disc outer diameter
  • Weight of caliper without bracket: Approximately 60 kg
  • Overall dimensions: 220 x 240 x 260 mm
  • Pad specifications:
    • Organic pad area: 20,300 mm2, max wear: 7 mm
    • Sinter pad area: 16,350 mm2, max wear: 6 mm
  • Nominal coefficient of friction: μ = 0.4
  • Total piston area per caliper half: 127 cm2
  • Volume for each caliper at 1 mm stroke: 25 cm3
  • Volume for each caliper at 3 mm stroke: 76 cm3
  • Actuating time: 0.4 seconds
  • Pressure and drain connection: 1/4” BSP
  • Max operating pressure: 15.7 MPa
  • Recommended pipe size: 10/8 mm
  • Operating temperature range:
    • General: -20°C to +70°C
    • Wind turbine: -40°C to +60°C
Braking Torque Calculation Fundamentals
The braking torque is influenced by the number of brakes, braking force, and the outer diameter of the brake disc. The formula provided allows for the calculation of the braking torque, taking into account the clamping force and the coefficient of friction.
