Shiny Nickel coating enhances rust and corrosion resistant. Steel hubs are soldered with the cast-iron core so it is hard for dust, water and silk to intrude the ball bearing and shaft. Thus lessen the needs for maintainance.

The 2-stage ball bearing is made of heat-treated steel to increase friction and wear resistance. The heat treated swivel neck ensures a secure hold of the bearing balls in harsh situations. Has Z shape dual brake pedal - very light and easy to use.

These casters are designed for heavy industrial applications where operational dependability is a must. Swivel caster models are machined from drop forged steel. With cast-iron wheel, the casters can be used in high temperature working condition.

Very thick, that is true for both steel bracket and PA wheel. The caster itself is heavy and have strength to support up to few tons per caster. The Swivel head is combined of Flat and Cone Bearing so you will have no trouble operating.
