After using casters for a period of time, if cracks or wear appear on the wheel surface, when should the wheels be replaced?
The wheels should be replaced when three situations occur: ① Wheel surface cracks: Regardless of the size, if the cracks go deep into the wheel body or expand under load, which may cause the wheel body to break, replace them immediately; ② Excessive wear: If the thickness of the wheel surface is reduced by more than 1/3 compared with the new wheel, or there are obvious depressions and deformations on the wheel surface, which will affect the load-bearing and rolling smoothness, replace them; ③ Abnormal functions: If the casters deviate, the noise suddenly increases, or the brakes cannot stably clamp the wheels due to wheel surface wear/cracks, even if the wear is not serious, it is recommended to replace the wheels to avoid safety hazards.
For casters used outdoors, what performance or materials need special attention?
For outdoor environments (rainwater, ultraviolet rays, rough ground), focus on 3 points: ① Weather resistance of materials: Choose wheels that are resistant to ultraviolet rays and high and low temperatures (nylon wheels, modified PU wheels), and do not use ordinary rubber wheels to avoid aging and cracking; Choose galvanized steel or stainless steel brackets to prevent rust from rainwater; ② Wear resistance of wheels: The outdoor ground is rough (stones, sand), so the wheels need to be wear-resistant (nylon wheels, high-wear PU wheels) to prevent rapid wear; ③ Sealing and dust prevention: Choose casters with bearing seals to prevent sand and dust from entering the bearings and avoid jamming and wear.
How to maintain casters daily to extend their service life?
There are 4 core maintenance steps: ① Regular cleaning: Clean up foreign objects (dust, small stones) in the gaps between the wheels and brackets every week. In oily environments, wipe the wheels with a neutral detergent every month to prevent oil corrosion; ② Lubrication and maintenance: Inject grease into the bearings and rotating parts of the swivel casters every 3-6 months (do not use engine oil, as it is easy to absorb dust); ③ Wear inspection: Check the wheel surface (cracks, wear), bearings (abnormal noise), brackets (loosening/deformation), and brakes (sensitivity) every month. Repair or replace parts in time if there is a problem; ④ Avoid improper use: Do not overload, do not drag the equipment (to prevent impact on the wheels), and do not use it on the ground with many sharp objects to prevent scratches on the wheel surface.
When casters are jammed and cannot be pushed, what aspects should be checked to identify the problem?
Check in the following steps: ① Wheels: See if they are stuck by thread, gravel, etc., and if the wheel surface is deformed (rubber cracking, nylon breaking). Clean or replace the wheels; ② Bearings: Feel if the rotation is dry (lack of oil), rusty (humid environment), or jammed (damaged). Lubricate or replace the bearings; ③ Brackets: Check if they are deformed due to collision and if the rotating parts are stuck by solidified oil stains. Clean the oil stains or straighten the brackets, and replace them if they are severely deformed; ④ Load-bearing: Confirm whether the load exceeds the marked load capacity of the casters. If it is overloaded, replace the casters with higher load capacity.
When casters make loud noise during use, what may be the reasons? How to solve it?
Noise usually comes from three types of problems: ① Wheels and the ground: If the wheels are too hard (e.g., nylon wheels on tiles) or the ground is rough/has foreign objects, replace them with PU wheels/rubber wheels, clean up foreign objects on the ground, or lay quiet floor mats; ② Bearings: If the bearings are dry due to lack of oil, worn, or have dust, inject lithium-based grease every 3-6 months, and replace the bearings if there is jamming or abnormal noise; ③ Brackets: If the screws are loose or the rotating parts of the swivel casters are worn, tighten the screws, check the swivel ball bowl, and replace the bracket if there is clearance.
What are the easily overlooked but important details when installing casters?
Four points need to be noted: ① Matching of mounting holes: The spacing and diameter of the holes at the bottom of the equipment must be completely consistent with those of the caster bracket. Do not drill holes forcibly or install them in a misaligned way to avoid bracket breakage; ② Moderate tightening force: Use matching screws (galvanized, stainless steel) and tighten them according to the torque recommended by the manufacturer. Too loose will cause loosening, and too tight will deform the bracket; ③ Uniform load-bearing: The installation height error of all casters should be ≤ 2mm to prevent a single caster from being suspended and other casters being overloaded; ④ Distinguishing positions: Install swivel casters and fixed casters according to the design (e.g., "swivel at the front + fixed at the rear"), and do not install them in reverse, which will make the equipment difficult to control.
