CUSTOMIZED SOLUTIONS
Casters are widely used in modern industry and logistics. Whether used in warehouse equipment, medical devices, or industrial production lines, casters play an irreplaceable role in movement and support. As a professional caster supplier, Giessen offers a wide range of high-quality casters suitable for various load and environmental requirements. This article provides a comprehensive understanding of casters, covering installation, maintenance, selection, and usage precautions, to help customers understand how to extend caster life and improve efficiency.
A caster is a mechanical part installed on the bottom of equipment to enable flexible movement. A standard caster consists of the following components:
Wheel: The part that directly contacts the ground and can be made of polyurethane, rubber, nylon, steel, etc.
Bearing: Located inside the wheel core, it ensures smooth wheel rotation.
Bracket: Supports the wheel and connects to the equipment chassis.
Mounting Plate (Stem): Used to secure the caster to the equipment. Different wheel materials and structures determine a caster's load capacity, wear resistance, and applicable environments.
Based on their rotation and mounting methods, casters can be categorized as follows:
| Type | Features | Applicable Scenarios |
| Fixed casters | Move only in a fixed direction | Conveyor belts, storage racks |
| Swivel casters | Rotate 360° for high flexibility | Tool carts, medical equipment |
| Brake casters | Equipped with a brake | Medical equipment, office furniture |
| Light- to medium-duty casters | Load range generally 50-200kg | Small industrial equipment, carts |
| Heavy-duty casters | Load capacity up to several tons | Large logistics equipment, heavy machinery |
Choosing the right caster is the first step to ensuring equipment safety and operational efficiency.
Before installing casters, please note the following:
Confirm the equipment load: Select a caster with the appropriate load capacity based on the weight of the equipment.
Inspect the mounting surface: The mounting surface should be flat and solid to ensure stable caster support. Tool Preparation: Common tools include wrenches, electric screwdrivers, and levels.
Caster installation typically involves the following steps:
Securing the bracket: Secure the bracket to the bottom of the device using bolts or welding.
Installing the wheel: Insert the wheel into the bracket bearing and confirm that the wheel rotates smoothly.
Adjusting the height and level: Ensure the device chassis is level to prevent shifting or tilting during use.
Test Run: Gently push the device to confirm smooth movement without unusual noises or jerking.
Wheel rotation is not smooth: This may be due to insufficient bearing lubrication or foreign objects being stuck.
Loose mounting bolts: Regularly check the bolt tightness after extended use.
Uneven wheel wear: This may be due to uneven load distribution or the wheel material being unsuitable for the floor environment.
Pro Tip: Choosing a reliable caster supplier can ensure caster quality and installation accuracy, reducing subsequent maintenance costs.
Casters can easily accumulate dust, dirt, or debris over extended use, affecting rotational performance. Maintenance recommendations include:
Weekly inspect the wheels for cracks or wear.
Clean the wheel surface and the bearings.
Properly lubricate the bearings to maintain smooth operation.
Long-term operation can cause fixing bolts to loosen. It is recommended to inspect them monthly and tighten or replace them if necessary.
Caster life is affected by a variety of factors, including the following:
| Factor | Impact Description | Recommended Actions |
| Excessive load | Exceeding the rated load can easily cause wheel deformation | Select casters strictly according to specifications |
| Floor environment | Rough or corrosive surfaces accelerate wear | Choose wear-resistant or corrosion-resistant wheel materials |
| Frequency of use | High-frequency movement accelerates bearing wear | Lubricate regularly and replace wheels promptly |
| Ambient temperature | High or low temperatures affect the elasticity of the wheel material | Choose a wheel material suitable for the temperature environment |
Through scientific maintenance and proper use, the life of casters can be significantly extended.
Industrial equipment is mostly medium-to-large. Consider the following when selecting casters:
High load capacity (typically over 500 kg)
Excellent shock resistance to ensure equipment stability during movement
Optional universal casters with brakes to enhance operational safety
The medical environment has strict requirements for casters:
Quiet and stable operation to avoid noise during movement
Antibacterial wheels for easy cleaning and disinfection
Universal casters with brakes to ensure bed or equipment is secure
For warehousing and logistics applications, caster requirements include:
High load-bearing capacity and good wear resistance
Smooth gliding and reduced operational resistance
Environmentally adaptable, suitable for concrete and metal floors
Table Example: Caster Selection Reference for Different Scenarios
| Scenario | Recommended Type | Main Material | Features |
| Industrial Equipment | Heavy-Duty Swivel Caster | Polyurethane/Steel | High-Load, Vibration-Resistant |
| Medical Equipment | Medium-Duty Caster with Brake | Nylon/Rubber | Quiet, Easy to Clean |
| Warehousing and Logistics | Fixed Caster + Swivel Combination | Polyurethane/Rubber | Wear-Resistant, Smooth Glide |
Wheel Difficulty Rotating
Cause: Bearing Oil Depletion, Foreign Objects Stuck
Solution: Clear Debris and Add Lubricant
Wheel Wear Excessively
Cause: Excessive Load or Uneven Floor
Solution: Replace Wheels with Suitable Loads or Adjust Flooring
Brake Failure
Cause: Worn or Improper Brake Components
Solution: Regularly Inspect the Brake System and Replace Components as Necessary
