We got 2 types nylon material of rollers and pulleys in our eBay shop for this auction, we use NYLON 6 (POLYAMIDE 6) to make these wheels. Product Description
Unlike most other nylons, nylon 6 is not a condensation polymer, but instead is formed by ring-opening polymerization; this makes it a special case in the comparison between condensation and addition polymers.
Nylon 6 fibres are tough, possessing high tensile strength, as well as elasticity and lustre. They are wrinkleproof and highly resistant to abrasion and chemicals such as acids and alkalis. The fibres can absorb up to 2.4% of water, although this lowers tensile strength. The glass transition temperature of Nylon 6 is 47 °C
As a synthetic fibre, Nylon 6 is generally white but can be dyed to in a solution bath prior to production for different colour results. Its tenacity is between 6 and 8.5 gm/den with a density of 1.14 gm/cc. Its melting point is at 215 °C and can protect heat up to 150 °C on average
Self-lubricating (low coefficient of friction)
Excellent Wear and Abrasion resistance
Noise Reduction
High Impact strength
Non-toxic
All our products are precisely machined. Injection moulding never produces precise parts. And moulded nylon parts have air cavities inside them. Air Cavities causes vibration at the high rotation speed
We used only licensed bearing from large manufacturers
Important: Wheels that will be exposed to water (rain) should be fitted with stainless steel bearings.
