Brake Caliper DH 035 FPA Overview

The Brake Caliper DH 035 FPA is a spring-activated, pneumatically released braking device designed for industrial applications. It features automatic adjustment to compensate for friction block wear and is compatible with various thruster sizes and brake disc thicknesses.

Key Features

• Spring activated and pneumatically released mechanism
• Automatic adjustment for friction block wear
• Mounting orientation: at right angles to the brake disc
• Thruster options: 065, 085, 095, 115, or 125
• Thruster mounting available on right or left side
• Brake disc thickness compatibility: 12.5 mm, 25 mm, 30 mm, or 40 mm

Ordering Example

Example: DH 035 FPA - 095 R - 12.5 indicates a DH 035 FPA brake caliper with thruster 095 mounted on the right side and a brake disc thickness of 12.5 mm.

Technical Specifications

Braking Torque and Clamping Force

The braking torques are calculated based on a theoretical friction coefficient of 0.4. The table below summarizes braking torque (Nm) for different thruster sizes and brake disc diameters:

Air Pressure and Volume Requirements

• Minimum air pressure: 5 bar (some thrusters require minimum 1.7 bar or 6.5 bar)
• Maximum air pressure: 8 bar
• Maximum air volume per activation varies by thruster size, ranging from 72 cm³ to 460 cm³

Weight

• Brake caliper weights range from 10.9 kg to 14.9 kg depending on configuration

Dimensional Data

Dimensions vary based on brake disc thickness and thruster mounting side. Key dimensions include:

Values in parentheses indicate dimensions accounting for maximum friction block wear.

Connection Details

• Compressed air connection for thrusters 085 and 095: G1/2"
• Compressed air connection for thrusters 115 and 125: G1/4"
• Thruster mounting side affects connection type

Summary of Critical Parameters and Recommendations

• Ensure air pressure is maintained between minimum and maximum specified values for reliable operation
• Select thruster size based on required braking torque and air volume capacity
• Account for friction block wear in dimensional planning and automatic adjustment feature
• Confirm correct thruster mounting side (right or left) to match machine configuration
• Verify brake disc thickness compatibility before ordering
