The components for the wheel; the outer race, bearings and inner race are assembled using an automated turntable system.

Three seals; the inner, intermediate and outer are placed on the wheel

The wheel is then conveyed through a swaging press to lock the outer seal in position

An orbital riveting system is used to attach the wheel to a trolley bracket

Once the wheel is assembled to the bracket, it is greased and capped.

Our standard is a high temperature, high pressure molybdenum based grease.

The final assembly step joins the assembled chain and trolleys.
