Thinking of what are selection criteria and environmental conditions are for a castor? This is a first question to be answered before choosing an appropriate wheel.

Such as, if you are seeking a castor for hospital beds, and thermoplastic elastomer wheel is better than polyamide wheel. It has well-performances in quiet reliability and labor-free, particular it is remarkable in absorb-shaking while is running on the seamed floor. Polyamide wheel will be a good choice for industry or others.

RUBBER WHEEL	POLYAMIDE WHEEL	POLYREUTHANE WHEEL
An economical wheel as a standard one, which generally use on light load equipment for short distance transportation.	Well-performance in corrosion-resistant and water influence.	Well-performance in corrosion-resistant and water influence, but it is better than polyamide wheel while is running in motion.
THERMOPLASTIC ELASTOMER WHEEL	ELECTRIC CONDUCTIVE WHEEL
Thermoplastic elastomer wheel is made with high grade bouncy materials. Labor-free, running smooth and quiet, particularly, it is remarkable in absorb-shaking while is running on seamed floor.	“Hydride “materials in high and pour grade. Well-performance in temperature-durable, chemistry-resistant (acidity, alkaline & salt). It is made by thermoplastic elastomer with composite & special electric conductive material, and manufactures in well-processing under EMI standard. It’s reliable and doing well in permanently.	NON MAGNETIC WHEEL The leakage resistance of <104 ohm. ELECTRIC CONDUCTIVE WHEEL The leakage resistance of <106 ohm. ANTI-STATIC WHEEL The leakage resistance of <109 ohm.
