To properly maintain them, you first need to understand the structure and classification characteristics of medium- and light-duty casters.
Light-duty casters typically carry loads under 50 kg and are suitable for lightweight equipment and furniture. Medium-duty casters: They generally have a load capacity between 50kg and 200kg and are used for medium-load transport vehicles and machinery.
Wheel: These wheels come into direct contact with the ground and are commonly made of polyurethane (PU), rubber, nylon, or nylon composites.
Bearing: These wheels ensure smooth rotation and are commonly made of ball and roller bearings.
Bracket: The metal part that connects the equipment to the wheel and is commonly made of carbon steel, stainless steel, or aluminum alloy.
Brake (if present): These wheels are used to secure the equipment and prevent accidental movement.
Fixed casters: These wheels can only roll in one direction and are suitable for linear movement.
Swivel casters: These wheels can rotate 360 degrees for flexible direction adjustment and are widely used in logistics equipment.
A correct understanding of potential problems with casters during use is essential for effective maintenance.
Wheel Wear: After prolonged use, the wheel surface can become severely worn, affecting rolling performance. Bearing Damage: Bearing failure can cause the wheel to stick or make unusual noises.
Deformed or Loose Bracket: Deformation of the bracket due to excessive load or collision can affect the stability of the caster.
Brake Failure: Failure of the brake mechanism may pose a safety hazard.
Regular Cleaning: Prevent dust and debris from entering the bearings and wheel surfaces.
Apply the correct load: Avoid exceeding the caster's load capacity.
Avoid Impact and Impact: Reduce equipment collisions and protect the bracket and wheel.
Environmental Protection: Prevent damage to caster components from humid or corrosive environments.
Attention to technical details during maintenance can effectively extend the life of the caster and ensure its performance.
Cleaning Frequency: A comprehensive cleaning is recommended monthly or quarterly, depending on the frequency of use.
Cleaning Method:
Use a soft brush or compressed air to remove dust from the wheel and bearing.
Heavily oily parts can be cleaned with a non-corrosive detergent. Lubrication Method:
Apply a suitable grease (such as lithium-based grease or polyurea grease) to the bearings and rotating shaft.
Avoid excessive grease to prevent dust absorption.
Bearing Condition Check:
Feel the bearing for smooth, unobstructed rotation.
Auscultate the bearing for any unusual noises.
Replacement Interval:
Bearings for medium- and light-duty casters are generally recommended to be replaced every 2-3 years, depending on the operating environment.
Preventative Measures:
Use sealed bearings to prevent dust and moisture intrusion.
Maintain a good lubrication system to delay bearing wear.
Visual Inspection:
Inspect the wheel surface for cracks, pits, and deformation.
Wear Depth Standard:
Wheel Material; Recommended Replacement Wear Depth (mm); Description: Polyurethane; ≥3; Affects load-bearing and rolling performance; Rubber; ≥4; Affects anti-slip and shock absorption performance; Nylon; ≥2; Fragile and requires prompt replacement.
Maintenance Recommendations:
Minor wear can be delayed by cleaning and lubricating. Replace the wheel promptly when it reaches the replacement standard.
Bracket Inspection:
Ensure there are no cracks or deformation, and that the connections are securely fastened.
Perform regular rust prevention treatment on metal brackets.
Brake System Maintenance:
Check the brake pedal for flexibility to ensure reliable braking.
Lubricate the mechanical brake regularly.
Inspect the rubber brake pads for wear.
A systematic maintenance process helps managers efficiently complete caster maintenance.
| Inspection Details | Key Points | Frequency |
| Wheel Appearance | Observe the wheel for wear and cracks | Daily or per shift |
| Bearing Rotation | Check that the wheel rotates smoothly and unobstructed | Daily or per shift |
| Bracket Tightening | Verify that the bracket is securely connected to the equipment and is not loose | Weekly |
| Brake Function | Test that the brakes are reliable and effective | Weekly |
| Cleaning the wheel and bearings | Remove dust and debris, and lubricate appropriately | Monthly |
Tools:
Hexagonal wrench, screwdriver
Soft-bristled brush
Grease gun
Materials:
High-quality grease (lithium-based, polyurea-based)
Rust inhibitor
Cleaning agent (non-corrosive)
| Misconceptions | Correct Understanding and Practices |
| Focusing solely on wheel maintenance while ignoring bearing and bracket maintenance | Wheels, bearings, and brackets all require regular inspection and maintenance |
| Over-lubrication causes dirt to adhere | Use an appropriate amount of grease to avoid over-lubrication |
| Using casters with excessive loads | Strictly use within the rated load to avoid damage |
| Ignoring environmental impacts on casters | Implementing protective measures for special environments (such as moisture and corrosion) |
| Maintenance Phases | Specific Content | Person in Charge | Notes |
| Daily Inspection | Appearance, Rolling, and Braking Tests | Operator | Record and Provide Prompt Reporting of Abnormalities |
| Periodic Maintenance | Bracket Tightening and Rust Prevention | Maintenance Personnel | Regular Lubrication of Bearings |
| Quarterly Maintenance | Thorough Cleaning, Wheel and Bearing Replacement and Inspection | Maintenance Technician | Preventive Part Replacement |
