The Rotary ARO22 is a 22,000 lb four-post alignment lift — the heavier sibling of the ARO16 — built for shops that align medium-duty trucks, service vans, cutaways, and heavier commercial pickups. When you order rotary aro22 parts, you are keeping both the lifting equipment and the alignment geometry accurate, which means the slip plates, rolling rear slips, turn plates, and alignment-specific safety locks all have to be in shape. This page covers the ARO22 anatomy, the wear items that come due first, how to identify your specific ARO22 build, and where OEM matters most. If your shop is running the ARO22 as a dedicated truck-alignment station, the sections below map out the parts you should be watching before an alignment starts drifting off tolerance.
What the Rotary ARO22 is
The ARO22 is Rotary’s 22,000 lb four-post alignment lift, sized above the ARO16 for medium-truck alignment work. Four columns, hydraulic power in the control post, mechanical safety locks in every column, and flat-and-level runways engineered to alignment tolerances make the platform an alignment station rather than just a service four-post. Front slip plates, rolling rear slip plates, and turn plates handle the geometry. Because the ARO22 works under heavier vehicles all day, rotary aro22 parts earn their wear cycle and the alignment components need attention alongside the standard cable and lock service.
ARO22 alignment parts anatomy
The ARO22 shares the standard four-post parts groups — four corner cables, sheaves and roller assemblies, safety-lock ladders in each column, sliding jack rails, the hydraulic cylinder in the powerside column, and the power unit — and layers alignment-specific parts on top. Turn plates in the front runways handle steering-angle work. Rolling rear slip plates on the back runways let the rear axle relax during setup. Locking pins secure the plates during drive-on. Alignment-lift safety locks hold the runways at true level, which is not the same tolerance as a service-only four-post. Every group in rotary aro22 parts catalogs traces back to one of those anatomy sections.
Common wear items and service intervals
Lifting cables are the top-of-list replacement on any four-post, and the ARO22 is no exception — annual inspection and condition-based replacement per Automotive Lift Institute guidance, with attention to birdcaging, broken strands, and swaged-fitting corrosion. Layered on top, alignment shops watch turn-plate bearings, rolling slip-plate rollers and grease fittings, locking-pin springs, and the slip-plate locking mechanisms themselves. Air lines, lock-release airbags, hydraulic hoses, filter screens, latch springs, and sheaves round out the list. Most ARO22 owners plan a comprehensive cable-and-latch refresh around the ten-year mark and freshen the slip-plate bearings on a shorter cycle in high-volume alignment bays. Because the ARO22 sees heavier vehicles than the ARO16, the slip-plate bearings and rear rolling slips take more abuse and belong on a monthly walk-around, not an annual one.
How to identify your ARO22 configuration
Before ordering, pull the serial tag on the powerside column near the control post and record the full model designation and the complete serial number. The ARO22 has been produced in multiple runway lengths, column heights, and slip-plate configurations over its production years, and superseded parts do not always cross generations — the alignment-specific components in particular can differ from build to build. Rotary Solutions publishes the illustrated parts breakdown for every ARO22 build on their support site, and matching the exploded-view page number to your ticket saves everyone from returned parts. Our Rotary lift parts buyer’s guide walks the identification process step by step.
OEM versus aftermarket on alignment lifts
For safety-critical components — cables, safety locks, hydraulic cylinders, latch springs, and airbags — we recommend genuine OEM or ALI-tested equivalents. For the alignment-specific parts — turn plates, rolling slip plates, and locking pins — OEM is the safer path because alignment accuracy depends on the parts staying true to the original geometry. A slip plate with a dragging bearing throws readings just enough to chase your tail through the whole job. For non-load-bearing consumables like decals, drip trays, and jack pads, quality aftermarket rotary aro22 parts save real money. Our Rotary aftermarket parts collection labels the tiers clearly.
Installation and service notes
The ARO22 is field-serviceable, but alignment lifts demand more care during service because the flat-and-level tolerances are tighter than a plain service four-post and the load rating is higher than the ARO16. Cable replacement follows standard four-post procedure with the runways cribbed and the hydraulic pressure fully released. After any service that disturbs the runways, re-level the lift to the alignment-accuracy spec in the Rotary installation and operation manual before returning it to alignment work. Our 4-post lift parts guide covers general four-post cable and lock work in more depth.
ARO22 versus ARO16 and service four-posts
The ARO22 sits above the ARO16 in Rotary’s alignment family. The ARO16 is a 16,000 lb passenger-and-light-truck alignment lift; the ARO22 is the heavier 22,000 lb platform built for truck alignment work with heavier cables and columns. The alignment-parts family is shared in concept but the parts themselves are sized differently and generally do not interchange. Compared with a straight service four-post like the SM18, the ARO22 adds all the alignment components and uses alignment-grade safety locks. Verify the model on the serial tag before you buy rotary aro22 parts, especially for slip plates, turn plates, and locking pins.
Ordering the right ARO22 parts the first time
The quickest route is to send us the serial number and the parts-breakdown page number, and we will confirm the current supersession before shipping. Start on our parts lookup page, or call 800-674-9302 and we will pull the exploded view with you on the line. We stock the common rotary aro22 parts — cables, safety locks, turn plates, slip-plate components, cylinders, and seal kits — and drop-ship the less-common items direct from Rotary Solutions. Call 800-674-9302 and we will get you back to alignment work without a guessing game.
