Shock Absorbing Caster Parameter Encyclopedia: Selection Guide, Working Principle, Specifications, Usage & Performance Introduction

Shock absorbing casters, also known as vibration damping casters, are special industrial caster products designed to reduce impact vibration during equipment movement, improve operation stability, and protect loaded goods and ground surfaces. They are widely used in logistics handling equipment, medical devices, precision instrument carriers, aerospace ground equipment, new energy production lines and other industrial scenarios.

1. Working Principle of Shock Absorbing Casters

The core working principle of shock absorbing casters is based on the elastic energy absorption and damping consumption mechanism of elastic components. The main structure includes caster wheel, bearing assembly, shock absorption module (spring, rubber damping block, polyurethane elastic component or air damping structure) and mounting bracket. When the caster encounters uneven ground, impact load or sudden acceleration and deceleration during operation, the elastic component in the shock absorption module will produce adaptive deformation, absorb the impact energy generated by vibration, and convert part of the kinetic energy into heat energy through damping effect to dissipate, so as to reduce the vibration transmitted to the upper equipment, avoid damage to precision components and loose goods, and reduce the noise generated by collision between caster and ground at the same time.

2. Selection Guide for Shock Absorbing Casters

When selecting shock absorbing casters, users should comprehensively consider the following core dimensions to ensure that the products meet the actual use requirements:
1) Load demand: The total load capacity of the selected casters should be 1.2 to 1.5 times of the total weight of the equipment plus loaded goods, leaving a safety margin to avoid overload damage. It is necessary to calculate the single caster load according to the number of casters installed on a single equipment.
2) Use environment: Select wheel and bracket materials according to the ground condition, temperature range, corrosion degree and other environmental factors of the use scenario. For example, polyurethane wheels are suitable for smooth indoor ground, rubber wheels are suitable for uneven outdoor ground, and stainless steel brackets are suitable for corrosive scenarios such as food processing and chemical industry.
3) Shock absorption requirements: Select the appropriate shock absorption stroke and elastic component type according to the shock resistance level required by the loaded equipment. Precision instruments need to choose casters with long stroke and high damping coefficient, while ordinary logistics equipment can choose conventional shock absorption models.
4) Installation method: Select matching installation types such as flat plate mounting, bolt mounting, rod mounting according to the reserved installation interface of the equipment.
5) Movement demand: Select fixed type, universal type or universal type with brake according to whether the equipment needs steering and fixed positioning.

3. Common Specifications of Shock Absorbing Casters

The above specifications are common standard models, and non-standard customized products can be provided according to special application scenarios.

4. Correct Usage Methods of Shock Absorbing Casters

To ensure the service life and shock absorption effect of shock absorbing casters, the following usage specifications should be followed:
1) Installation: Ensure that the mounting interface is flat and firm during installation, and tighten all fasteners according to the torque requirements specified in the product manual to avoid loosening during operation.
2) Load limit: Do not exceed the rated load capacity of a single caster for a long time, and avoid instantaneous impact overload caused by falling heavy objects.
3) Movement speed: Control the moving speed of the equipment within the rated speed range of the caster (usually 3 ~ 5km/h for ordinary industrial models), avoid sudden braking and sharp steering at high speed, so as to prevent damage to the shock absorption module.
4) Regular maintenance: Check the tightness of fasteners, wheel wear, elastic component deformation and other conditions every 1 to 3 months according to the use frequency, add lubricating oil to the bearing part regularly, and replace damaged components in time.
5) Adaptation to scenarios: Avoid long-term use in environments beyond the applicable temperature range and strong corrosion environment, so as to prevent performance degradation of elastic components and bracket corrosion.

5. Advantages and Applicable Limitations of Shock Absorbing Casters

Core Advantages

1) Excellent vibration and impact reduction performance, which can effectively protect precision equipment, fragile goods and ground surfaces, reduce equipment failure rate and goods damage rate.
2) Low operation noise, which can reduce the noise level in the workplace by 10 ~ 20dB compared with ordinary casters, and meet the noise reduction requirements of office, medical, precision workshop and other scenarios.
3) High stability, which can reduce the jitter of the equipment during movement, avoid the tipping risk caused by uneven ground, and improve the safety of handling operation.
4) Long service life, the elastic buffer structure can reduce the impact force borne by the caster wheel and bracket, and extend the overall service life of the caster by more than 30% compared with ordinary casters under the same working conditions.

Applicable Limitations

1) Compared with ordinary industrial casters, the purchase cost of shock absorbing casters is higher, which is more suitable for scenarios with vibration reduction requirements, and the cost performance of use in ordinary low-demand logistics scenarios is relatively general.
2) The overall installation height is higher than that of ordinary casters of the same load level, which requires reserved enough installation space for the equipment.
3) The elastic damping component has a certain service life, and regular inspection and replacement are required in high-frequency use scenarios to maintain the shock absorption effect.
