N Series – Untyred Nylon Wheels
Plain untyred nylon wheels are the least expensive type of wheel. They are light in weight, and are resistant to impact, abrasion, corrosion, and the effect of many common chemicals. They can be fitted with bearings but are most often used with their nylon bores running on a smooth steel axle. No lubrication is necessary, but they will benefit from being oiled. Nylon wheels are resistant to oils fats, alkalis in general, soaps and detergents but should not be used in contact with acids.
