LARGE QUANTITIES FOR THE BEST PRICE AVAILABLE. 45MM SQUARE FLAT NYLON PULLEY WHEEL WITH BEARING
We got 2 types of nylon material of rollers in our eBay shop for this auction, we use NYLON 6 (POLYAMIDE 6) to make these wheels.
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 luster. 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.
