Wear components guide the flights along the tank floor and the return tracks, absorbing all of the system's frictional wear. We manufacture wear shoes from UHMW-PE with a molecular weight of approximately 5 million g/mol in floor, return, and lug versions — including Wear Alert shoes with a built-in visual wear indicator that exposes a warning color once 50% of the thickness has worn away, taking the guesswork out of replacement timing. They are complemented by UHMW-PE wearstrips with slotted holes that compensate for thermal expansion and milled ends for a smooth flight transition. The material contains UV inhibitors and resists chemicals — typical replacement intervals are measured in years, not months.

Molded UHMW-PE Black Repro wear shoes (~5 million g/mol molecular weight) — excellent durability and wear resistance at a far lower price than virgin UHMW.
Wear shoes with a built-in visual wear indicator — a colour appears once 50% of thickness is worn, removing the guesswork on replacement.
HMAX UHMW-PE wearstrips (~5 million g/mol molecular weight), UV inhibited. Slotted holes allow thermal expansion; mitered ends give smooth transitions.
As a rule — when the working thickness approaches half of nominal. Wear Alert shoes solve this systematically: once 50% of the thickness has worn away, a yellow indicator is exposed, visible when the tank is drained, so the replacement decision requires no measurements.
The floor shoe guides the flight along the tank floor while it collects sludge; the return shoe rides on the upper return tracks. The lug version has an additional mounting to the chain attachment. All are 13 mm thick with standard hole spacings.
The higher the molecular weight of the polyethylene, the greater its resistance to abrasion and impact. The 5 million g/mol material extends replacement intervals and handles grit and hard debris in the sludge well.
Yes — HMAX wearstrips have four slotted holes that allow thermal movement and one locating hole, so they do not buckle as the temperature changes. The bevel-milled ends ensure a smooth transition of the flight shoes between sections.
