Product Description

The document details rubber buffers composed of natural rubber blocks vulcanised onto galvanized steel plates with central threads. These buffers vary in density to provide different damping characteristics suitable for shock absorption and vibration control.

Applications

Rubber buffers are used to absorb kinetic energy and reduce impact shocks in equipment such as cranes, rail wagons, and stopping mechanisms. They also function as limiting elements to control extreme oscillations and resonance frequency shifts, and can be integrated into flexible guide rails.

Installation and Fitting

Buffers can be mounted on fixed or mobile machinery parts. For enhanced damping, two buffers may be installed in series opposite each other to increase shock absorption capacity.

Technical Specifications

• Buffer Types: GB2517, GB3036, GB5045, GB5068, GB7590, GB90110.
• Load Capacity: Peak loads range from 15–20 kg (GB2517) up to 800 kg (GB90110), with normal operating loads recommended at about half the peak load.
• Dimensions: Diameter ranges from 25 mm to 90 mm; height ranges from 17 mm to 110 mm.
• Thread Sizes: Metric threads from M6x18 to M12.

Performance Data – Load vs Deflection

Extensive load-deflection curves illustrate the relationship between applied load (kg) and deflection (mm) for various buffer models, essential for selecting appropriate buffers based on stiffness and energy absorption needs.

• GB2517: Max load ~20 kg, deflection up to 20 mm.
• GB3036: Max load ~80 kg, deflection up to 40 mm.
• GB5045 & GB5068: Max loads up to 400 kg, deflections up to 30 mm.
• GB7590 & GB90110: Max loads up to 1000 kg, deflections up to 40 mm.

Additional series such as FA, IAC SD, SANDWICH, MD, SCB, and FDA provide varied load-deflection profiles and natural frequency data, indicating suitability for diverse vibration damping applications.

Key Parameters and Recommendations

• Peak load values correspond to short duration (~1 second); normal loads should be about half peak load for durability.
• Deflection data informs buffer stiffness and energy absorption capacity.
• Buffers can be combined in series to enhance damping performance.
• Selection criteria should include load, deflection, natural frequency, and installation context.

Detailed Buffer Load-Deflection Characteristics

Graphs for multiple buffer models (e.g., AD series, ADF, ADM, ADP) show load capacities from tens to thousands of kilograms and deflections typically from 0 to 5 mm, with some models allowing up to 30 mm. Load-deflection curves generally indicate elastic or progressive deformation behavior.

Material Variants and Performance

• Sandwich Series: Very high load capacity up to 16,000 kg with deflections up to 5 mm, ideal for heavy-duty applications.
• GB Series: Broad load range (20–1000 kg) with deflections up to 40 mm, suitable for medium loads.
• White and White Hollow: Moderate load capacities with smaller deflection ranges, suited for lighter loads.

FDA Series Buffers

FDA series buffers (FDA-25 to FDA-100 and FDA1 to FDA9) exhibit scalable load capacities from hundreds to thousands of kilograms and deflections up to 30 mm, supporting a wide range of load requirements.

SCB Series Buffers

SCB buffers (various sizes) include load-deflection and natural frequency data, with load capacities from 10 to 1000 kg and deflections up to ~3 mm. Natural frequency information highlights their suitability for vibration-sensitive applications.

Configuration and Application Notes

Buffers can be arranged in parallel or series configurations to tailor mechanical response and serve as stops against extreme movements, enhancing safety and performance in dynamic load scenarios.

Summary of Critical Information

• Load Capacity: 10 kg to 16,000 kg depending on type and material.
• Deflection Range: Typically 0–5 mm; some models up to 30–40 mm.
• Material Impact: Sandwich materials offer highest load capacity; GB and FDA series cover medium to high loads; White variants suit lighter loads.
• Dynamic Properties: SCB series includes natural frequency data for vibration damping considerations.
• Configuration: Parallel and series arrangements recommended to optimize damping and safety stops.

This comprehensive data supports engineers and designers in selecting appropriate rubber buffers for energy absorption, shock mitigation, and controlled deflection in mechanical systems.
