Step Chain Roller; 100x25, Hub Type Roller, With Bearing 6206, Pin 30
The step chain and step roller have two design structures, which are the integrated roller and the wheel hub roller. The integrated roller is made up of tires and bearings, while the hub type roller is made up of tires, hubs, and bearings. The hubs can be made of either engineering plastic (PA) or metal, with PA being the standard and metal being an option based on customer requirements. However, it is rare for metro customers to require metal hub step chain rollers.
The step chain plays a crucial role in supporting the weight of the escalator, and the step chain roller is an important component that bears significant pressure. Typically, the hub type roller is used for the step chain.
The step chain rollers are made of hydrolysis-resistant polyurethane, while the hubs are made of PA. The eligibility tests for the step chain rollers include anti-hydrolysis and oil hydrolysis tests, both of which last for 250 hours, as well as a life test run time of 5000 hours.
