LARGE QUANTITIES FOR THE BEST PRICE AVAILABLE. 40mm nylon roller wheel with bearing
We got 2 types 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 fibers 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 fibers 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 color 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 molding never produces precise parts. And molded nylon parts have air cavities inside them. Air Cavities causes vibration at 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.
