In industrial, logistics and commercial equipment, the reliability of medium-duty casters (usually carrying 100-500kg/piece) directly affects the stability, operational safety and service life of the equipment. How to choose medium-duty casters that truly meet high standards? The following are key quality requirements:
1. Load-bearing capacity and structural strength
✅ Core requirements:
Dynamic load ≥150kg/wheel, static load ≥300kg/wheel (to ensure long-term load without deformation).
Thickened steel plate/cast iron bracket, impact and bending resistance, suitable for frequent moving scenes.
❌ Risks of inferior casters:
Overloaded rear wheel frame breaks, causing equipment to tip over or personnel to be injured.
2. Wheel material and ground adaptability
✅ Core requirements:
Polyurethane (PU) wheel: silent, wear-resistant, suitable for hard floors (such as epoxy floors, cement floors).
Nylon wheel: oil-resistant and corrosion-resistant, suitable for factory workshops.
Rubber wheels: shockproof, strong grip, suitable for uneven ground.
❌ Risks of inferior casters:
Wheel surface cracking, degumming, increasing pushing resistance, and even damaging the ground.
3. Bearing type and smoothness
✅ Core requirements:
Precision ball bearings (Ball Bearing): suitable for high-frequency movement, pushing and pulling more labor-saving.
Double seal dustproof design: prevent debris and dust from entering, and extend service life.
❌ Risks of inferior casters:
Using ordinary shaft sleeves, it is easy to rust and jam, increasing maintenance costs.
4. Braking and stability
✅ Core requirements:
Dual brake system (wheel brake + total brake): ensure that the equipment is flexible when moving and stable when working.
Low center of gravity design: reduce the risk of equipment rollover, especially suitable for tall shelves or precision instruments.
❌ Risks of inferior casters:
Thin brake pads are easy to wear, causing the equipment to slide unexpectedly.
5. Corrosion resistance and service life
✅ Core requirements:
Galvanized/stainless steel material: rust-proof and corrosion-resistant, suitable for humid or chemical environments.
Industrial-grade rubber/polyurethane wheels: anti-aging, avoid cracking after long-term use.
❌ Risks of inferior casters:
Ordinary painted brackets are prone to rust, shortening the life of casters.
How to identify high-quality medium-duty casters?
🔹 Look at the certification: pass ISO 9001, DIN/EN 12530 and other international standards.
🔹 Measure the load: dynamic load should be ≥ 1.5 times the nominal value (to ensure safety margin).
🔹 Test push: high-quality casters rotate flexibly without jamming or abnormal noise.
