Erbessd EI-Pulley Ace Sheave Alignment Laser

Compact Class II ultra-green laser sheave alignment system for belts, pulleys, sprockets, and related plant equipment — 0.070 in accuracy (OEM: 7× industry standard), 60 in beam spread at 3 ft, 1/16 in line width at 30 in, 40 arc-min level vial, three IP67 magnetic retro-reflective targets, and foam-filled carrying case.

Key advantages

Ultra-green visibility — OEM states 400% greater visibility than red-beam lasers; usable for positive-tracking on retro-reflective targets.
0.070 in accuracy — lab-grade claim vs string/straight-edge methods; compact 1.75×6.75×0.625 in body for small sheaves.
Three adjustable targets — retro-reflective, hard-anodized aluminum, rare-earth magnets, IP67, adjustable over 1 in.
Laser level use — check height/flatness of motor and gearbox mounting plates.
Kit in case — tool + 3 targets + rigid foam-filled case; 2×AAA power (up to 10 h on product page).

Typical applications

Belt and sheave alignment to reduce vibration and bearing wear.
Sprocket, gear-train, roller, platform, and conveyor alignment.
Motor/gearbox base flatness and height checks with the level vial.
Tight-space alignments on small-diameter sheaves.

Selection guide

Laser — Class II; product page lists power 2×AAA up to 10 h (datasheet also notes alkaline runtime examples).
Optics — beam spread 60 in @ 3 ft; line width ≈1/16 in @ 30 in; level vial 40 arc-min.
Targets — three retro-reflective knobs, 1-1/4 in dia × 1 in, IP67 magnets.
Scope — sheave tool + targets + case (confirm any spare targets on RFQ).

Common mistakes

Treating it as a shaft-coupling dual-laser aligner — EI-Pulley Ace is a sheave/belt plane tool.
Using non-reflective targets or skipping magnetic seating on dirty sheave faces.
Expecting outdoor Class 1 long-range shaft alignment performance.
Ignoring battery type/runtime planning for all-day routes.

When to RFQ / what to tell us

FAQ

Q: What is in the kit? A: OEM lists the sheave alignment tool, three retro-reflective targets, and a foam-filled carrying case.

Q: Shaft alignment or sheave alignment? A: EI-Pulley Ace is for belts/sheaves/sprockets and similar plane alignment — not a dual-laser shaft coupling system.

Q: What should I send for a quote? A: Kit confirmation, spares, quantity, ship-to. Compatible with systems using Erbessd EI-Pulley Ace if you need a drop-in check — we do not claim authorized-dealer status.
