LiftMaster AH107 4-Inch Steel V-Groove Gate Wheels with Ball Bearings — Pair

The LiftMaster AH107 Power Wheels are a pair of 4-inch solid-steel V-groove wheels with ball bearings for appropriately designed track-supported sliding gates. LiftMaster identifies the AH107 pair with gold zinc plating and a gate capacity of up to 3,000 pounds in a suitable installation. Match the track, wheel mounting and complete gate support arrangement before ordering. The capacity is not a per-wheel rating or a guarantee that any existing gate structure can support that load.

Compatibility — Models, Versions and Exclusions

Evaluate the Track and Support Structure Alongside the Wheels

A wheel replacement should begin with the gate’s support and travel path. Damaged track, debris, an unsuitable mounting pocket or poor alignment can make a gate difficult to move even when a new wheel is fitted. Have the installer inspect both wheel locations, the track and the guide arrangement before deciding that the wheels are the only parts requiring attention.

The advertised capacity describes the intended wheel application, not the capacity of every bracket, axle, post or track beneath the gate. A heavy gate needs a suitable complete structure and protection against uncontrolled movement or derailment. Provide the gate weight if known, wheel diameter and photographs of the mounting arrangement so the replacement can be evaluated before the gate is lifted.

Specifications and Product Identification

Before Ordering

• Measure the existing wheel and axle arrangement with the gate safely secured.
• Confirm the gate load and that the installation uses the required V-groove/angle-track geometry.
• Inspect the track for damaged sections, obstructions and alignment problems.
• Determine whether mounting hardware also needs replacement; do not infer hardware quantities from a wheel photograph.

Package Contents and Separate Requirements

The manufacturer and supplier identify AH107 as a pair of wheels. Confirm the current carton’s axle, bolt and mounting-hardware contents before ordering additional materials. The wheel pair does not include a gate operator, complete track system or an engineered mounting assembly for an arbitrary gate.

Safety Warnings — Read Before Installation or Service

• WARNING: A heavy sliding gate can fall, roll or derail during wheel replacement and cause serious injury or death. Use a qualified gate installer.
• Secure and adequately support the gate before removing a wheel or axle. Do not rely on the operator to hold the gate in place.
• Disconnect automatic-operator power and keep people out of the gate path while the support system is being serviced.
• Verify stable support, guidance, free travel and the operator’s required safety tests before returning an automated gate to use.

Related Products and Important Differences

• LMWEKITU monitored wireless edge kit — a separate safety-system component to review on an automated gate where the operator approves it; it does not support the gate’s weight.
• LMRRUL monitored photo eye — a non-contact protection option for approved controls, separate from the mechanical wheel repair.

Frequently Asked Questions

Is the 3,000-pound figure for each wheel?

No per-wheel claim is made. LiftMaster’s accessory guide describes the AH107 pair for gates up to 3,000 pounds in a suitable installation.

Will any 4-inch wheel fit my gate?

No. Groove geometry, axle fit, mounting clearance, load and track arrangement must all be evaluated.

Is this the same as a heat-treated silver wheel?

LiftMaster distinguishes the gold-zinc AH107 from the heat-treated silver HT3000V in its accessory guide. Do not merge the specifications.

Will new wheels fix a bent track?

No. Track and mounting faults require correction as part of the repair.
