In the fields of industrial equipment, logistics and transportation, and medical equipment, casters are key moving parts, and their quality directly affects the service life and operational safety of the equipment. As a caster expert with 20 years of industry experience, Guangming Casters will explain professional purchasing tips for you.
1. Packaging process: the first line of defense for quality
High-quality casters usually have:
Standardized packaging: shockproof cartons or customized pallets
Complete labeling: clearly marking product parameters, load-bearing ratings and manufacturer information
Protective measures: corner reinforcement and moisture-proof treatment
Poor quality characteristics:
• Simple woven bag packaging
• No protective measures
• Product information missing
2. Bracket structure: the core guarantee of bearing capacity
Material identification
Quality standard:
Use positive tolerance cold-rolled steel plate (thickness error ±0.1mm)
Standard thickness of 6-inch caster is 5.75-6mm
Poor quality characteristics:
Use head and tail plates (uneven thickness)
Actual thickness is less than 30% of the nominal value
Process standard
Quality process:
Shot blasting (uniform pitting on the surface)
Six electroplating processes (salt spray test ≥96h)
Poor quality characteristics:
Simple spray painting
Visible welding burrs
3. Wheel body detection: the key to mobile performance
Geometric accuracy:
True roundness error ≤0.5mm
Axial runout ≤1mm
Surface treatment:
No Mold line, no bubbles
Uniform color (color difference ΔE≤1.5)
IV. Performance test: actual use verification
Rotation test:
Universal wheel should achieve 360° smooth rotation
Single finger can push (rotation torque ≤1N·m)
Load test:
No visible deformation under rated load
Temperature rise ≤15℃ after continuous operation of 20km
Professional advice:
Suppliers are required to provide:
Material test report
Salt spray test data
Load certification documents
Field inspection:
Process level of production workshop
Quality control system
Sample test:
200km durability test is recommended
Check wear and tear
MIYA professional tips: When choosing casters, you can't judge by price alone. Our 600 series industrial casters adopt military-grade standards, and all products are ISO9001 and SGS certified, providing you with real long-term value.
