  Heavy Duty Rubber on Iron Swivel Trolley Casters

Heavy duty Rubber on cast iron casters are very popular products in the caster market in any country. These Heavy Duty Casters are widely and frequently used in industry, so the quality is very important. 

The swivel caster for trolley are assembled from rubber on cast Iron Wheels, with double ball bearings and heavy duty brackets. Rubber is a kind of thermoplastic. It is impact resistant, has no traces, no pollution, and corrosion resistance, but it is not resistant to strong oxidants and halogen-hydrogen compounds. In addition, its rolling resistance is very small and does not absorb moisture, and will swell in aliphatic and aromatic hydrocarbons. As we know, bearings and brackets are the basic conditions that must be considered and referenced for loading capacity. So we purchase high-quality bearings and continuously improve the bracket. And these ruuber on cast iron Swivel Casters swivel flexible. And the iron core can make the wheel load larger, and the rubber surface can reduce noise and friction during use. Then the trolley wheel can be used longer.
