PNEUMATIC CALIPER BRAKES

Product catalog summary
Overview
Pneumatic caliper brakes are crucial for controlling the deceleration of machinery parts, especially in small to medium power applications. These systems integrate brake discs with pneumatic calipers to enhance production efficiency, reduce costs, and minimize errors.
Specifications
Brake discs are available in diameters from 200 to 600 mm and can be customized. The SA calipers use a rubber diaphragm piston and are self-aligning, requiring no wear adjustments. They should be kept away from heat sources.
Application and Selection
Choosing the right caliper brake is essential for optimal performance. Proper material arrangement on the disc is necessary to achieve the nominal torque value. For stop braking, a calculation not lower than F.S.2 is recommended.
Usage Recommendations
Compliance with EU directives 89/656 and 89/686 is advised to prevent accidents, ensuring the use of suitable protective devices. The spring-applied pneumatic caliper brakes require assembly and maintenance by qualified personnel.
Compliance and Disposal
The friction material is asbestos-free, and disposal should follow local laws (EU directive 75/442). The caliper brake must be used only on its designated machine.
Technical Data and Formulas
Key symbols include dynamic torque (Cd), total inertia load (J), and revolutions per minute (n). Formulas for calculating dynamic torque and heat dissipation are provided.
Product Variants
Combiflex calipers are modular, suitable for low or medium braking force applications, and offer flexibility in activation. The CX-NANO caliper is a miniature version for significant braking torques in limited spaces.
Reduced Torque Options
Combiflex calipers with reduced torque are designed for high sensitivity in braking, suitable for light materials. Various models offer different braking forces as a percentage of the standard caliper.
Graphs and Charts
Graphs illustrate the relationship between air pressure and torque, and the impact of pad wear on torque, aiding in understanding performance characteristics.
Specifications
Specifications for different caliper and disc models include dimensions, weight, air volume, tangential force, and maximum pressure. For example, the PR-5”N-25-SA model weighs 53 kg, with an air volume of 0.7 dm3, a tangential force of 14800 N, and a maximum pressure of 5 bar.
Procedures
The document details the procedure to calculate dynamic torque (Cd) using the formula: Cd = Rm · F, where F is the thrust force, Rm is the medium radius, and d is the disc diameter.
Norms and Recommendations
Refer to specific pages for detailed calculations, such as page 26 for braking force on different disc dimensions and page 4 for torque values.
Data Summary
Tables provide detailed specifications for models like PX-PZ and PZ, listing dimensions, inertia, weight, and RPM. For instance, the PX-PZ 250 model weighs 4 kg and operates at 2700 RPM.
Applications
Applications include the CX NANO caliper on discs with taper lock and the PZM-12-SA air applied pneumatic caliper.

PNEUMATIC CALIPER BRAKES-3

To control the deceleration of moving parts for small and medium powers, the best solutions is the combination of a brake disc with one or more pneumatic calipers. The discs are available in diameters from 200 to 600 mm, and can also be made to the customers’ specific designs. RE caliper brakes are used in a wide range of applications in order to satisfy all the customers’ needs. The SA calipers are actuated by a rubber diaphragm piston - that should be placed away from any heat source, they are self aligning, and do not require adjustments for wear. Per controllare la decelerazione di parti...
