VKSD Disc Brake Caliper for Industrial & Mining
Product catalog summary
Description: The VKSD and VKSD-VR disc brake calipers are designed for industrial and mining applications. These are spring-applied, hydraulically released brakes with two spring modules on either side of a mounting plate. The plate can accommodate brake discs of 20mm thickness or more, with a minimum disc diameter of 1000mm and no maximum limit. The VKSD-VR version is suitable for high-duty applications due to its excellent thermal capacity.
Features: The calipers weigh between 146 kg and 172 kg for the VR version. They operate with mineral oil-based fluid at a maximum pressure of 163 bar. The brake pad area is 36300 mm2 for standard and 59976 mm2 for VR. The working temperature range is -20°C to 70°C, with an optional range down to -40°C. The minimum disc diameter is 1000 mm, and the effective disc radius is the actual radius minus 0.095 m. Braking torque is calculated as the product of braking force and effective disc radius.
Specifications: The calipers feature stainless steel components and are painted to meet ISO 12944-5:2007 C5 environment specifications. They have a coefficient of friction of 0.4 and allow for a pad wear of 10mm. Floating (Mono Spring) versions and optional pedestal/bracket are available.
Performance: The table provides detailed specifications for various VKSD models, including air gap, braking force, release pressure, retraction pressure, and specific pad pressure. Braking force increases with a reduction in air gap setting, and nominal braking force assumes fully bedded-in pads.
