Price is for a pair of Ermes roller wheels. Each wheel is fitted with a choice of either a sliding delrin bush or a ceramic bearing, with a thinner bush face.

Wheels are machined from solid Delrin. The particular shape of the groove has been specially designed to elimate the problem of slippage of the rubbers in the contraction phase.

The measurements are: outer 36 mm, depth 16mm, and hole fits a 6 mm axis, for use with rubber up to 16 mm diameter.

NOTE: Roller head muzzles contain rotating bushes &/or bearings that require regular maintenance. Ensure after every use, regular freshwater washing takes place to remove any debris or saltwater. Avoid contact with dirt or sand as this will quickly degrade bearing surfaces. Bushes and bearings are consumable items that may need to be replaced, depending on conditions of use, load and correct maintenance.
