All Uni-Blade Retrofits

Your Match: E1, E4, E6, or PE6 Series

The patented Uni-Blade design (Patent No. 12,246,927) fits any OEM — selection takes only blade height and belt width. More than one series fits this cleaner; pick by the blade height and channel that match your mainframe bar — or send us a photo and we’ll match it.

Series	Blade Height	Channel Width	Bar Size	Part Numbers
E1	6-5/8”	7/16”	Up to 3/8”	E1M16–E1M70 (Ev-R-Wear) / E1U16–E1U70 (Standard)
E4	7-1/4”	9/16”	Up to 1/2”	E4M16–E4M70 (Ev-R-Wear) / E4U16–E4U70 (Standard)
E6	7”	9/16”	Up to 1/2”	E6M16–E6M70 (Ev-R-Wear) / E6U16–E6U70 (Standard)
PE6	6-3/8”	7/16”	Up to 3/8”	PE6M16–PE6M70 (Ev-R-Wear) / PE6U16–PE6U70 (Standard)

Blade width = belt width minus 2” — a 48-inch belt takes a 46-inch blade — part E1M46 in blue Ev-R-Wear or E1U46 in orange standard. Belt widths 18”–72”. MSHA Approved IC-379/01.

Why Crews Switch From OEM Blades

No more pins, no more beam clamps — the Uni-Blade installs to your existing pipe and bar with set screws. Release tension, swap the blade, re-tension. Done.
100% engagement, no chatter, no loose fit — full blade contact across the material path.
Custom widths without drilling — need the blade to match the material path? No additional holes required; just order the width you need.
Your choice of urethane — blue Ev-R-Wear™ (83A, the pick for high-abrasion service) or orange Standard (83A, the economical choice). Chemical (green, 80A), High Heat (red, 95A, service over 160°F), and FDA Food Grade (white) compounds available on request.
Keep your mainframe — the Superior structure and tensioner you already own stay right where they are.

GOOD TO KNOW

How to Order

1. Confirm your cleaner is the Superior Exterra® — the tag is on the mainframe, and a photo works. 2. Tell us your belt width and mainframe bar size so we can pick the series. 3. Pick your urethane and add it to your quote list. Our MSHA & OSHA trained crews can install during your next outage if you’d rather not touch it.
