LiftMaster LJ8950W Light-Duty Commercial Jackshaft Operator for Rolling Doors – Wi-Fi

HEAD ONLY — NO OVERHEAD RAIL INCLUDED OR REQUIRED

The LiftMaster LJ8950W is a light-duty commercial wall-mount jackshaft operator specifically designed for smaller rolling commercial doors and rolling grilles.

Unlike a residential wall-mount opener such as the LiftMaster 98022, the LJ8950W is engineered around light-duty commercial rolling-door applications including self-storage facilities, small warehouses, counter shutters, dock areas, and other smaller rolling service doors.

The operator mounts beside the door shaft, helping preserve overhead space while providing smooth DC operation, built-in Wi-Fi, myQ Smart Facility Access compatibility, Security+ 2.0 radio technology, and optional battery backup.

Important Application Note

The LJ8950W is designed for rolling doors and rolling grilles.

Door Size & Weight Capacity

The LJ8950W is intended for smaller, lighter commercial rolling doors.

Maximum Door Area

Up to approximately 180 sq. ft., subject to LiftMaster's dimensional and application requirements.

Maximum Door Height

Up to approximately 12 ft.

Maximum Door Width

Up to approximately 18 ft.

Maximum Door Weight

Up to 650 lbs in the standard configuration.

Up to 850 lbs when the required compatible LiftMaster battery backup is installed, subject to all LiftMaster door-size, shaft, balance, and installation requirements.

Door weight alone does not establish compatibility.

The door must also meet the manufacturer's requirements for shaft type, door dimensions, balance, sprocket configuration, mounting clearance, duty cycle, and entrapment protection.

Rated Duty Cycle

The LJ8950W is a light-duty commercial operator.

LiftMaster rates it for:

• Maximum 10 cycles per hour

• Fewer than 25 cycles per day

It is not intended as a continuous-duty industrial operator.

For doors with heavy traffic or substantially higher daily cycle requirements, select a commercial operator designed for the required duty cycle.

Typical LJ8950W Applications

The LJ8950W is particularly well suited for compatible:

• Self-storage rolling doors

• Small warehouse rolling doors

• Counter shutters

• Rolling service doors

• Smaller commercial rolling grilles

• Light-duty dock-area rolling doors

• Commercial outbuildings

• Low-cycle rolling-door installations

LJ8950W vs LJ8900W

These models look similar, but the intended door type is different.

LJ8950W

Designed primarily for:

• Rolling commercial doors

• Rolling grilles

LJ8900W

Designed primarily for:

• Sectional commercial doors

If the door travels upward in hinged sections on sectional track, investigate the LJ8900W.

If the curtain rolls around a barrel or shaft, the LJ8950W is the model generally associated with that application.

LJ8950W vs LiftMaster 98022

The LJ8950W should not be treated as a lower-cost substitute for a LiftMaster 98022.

LiftMaster 98022

• Residential application

• Sectional garage doors

• Battery backup included

• Automatic garage door lock included

• Residential myQ platform

• Up to 850-lb compatible doors

LiftMaster LJ8950W

• Light-duty commercial application

• Rolling doors and grilles

• Battery backup optional

• Commercial myQ Smart Facility Access

• Maximum 10 cycles/hour

• Fewer than 25 cycles/day

For a residential torsion-spring sectional garage door, start with the 98022:

Motor & Power

• Motor: 12V DC

• Input Power: 120V AC

• Frequency: 60 Hz

• Current Rating: approximately 1.5A

• Automatic thermal protection

• Permanent lubrication

• 3-prong power connection

The DC motor provides smooth start and stop operation, reducing abrupt mechanical movement and helping reduce wear on compatible door hardware.

Commercial Drive System

The LJ8950W uses a commercial internal chain-and-sprocket drive mechanism with approximately 63:1 gear reduction.

The operator supports compatible live-shaft and dead-shaft rolling-door configurations using the proper LiftMaster hardware and sprocket arrangement.

Always verify the actual shaft configuration before ordering.

Built-In Wi-Fi & myQ Smart Facility Access

Built-in Wi-Fi allows the LJ8950W to connect with LiftMaster's compatible commercial myQ platform.

Depending on the facility setup and services being used, myQ Smart Facility Access can provide features such as:

• Door status monitoring

• Remote access management

• Activity visibility

• Facility access information

• Real-time alerts

• Multi-door management

Available functionality may depend on current LiftMaster services, subscriptions, compatible devices, and network configuration.

Security+ 2.0

The LJ8950W supports LiftMaster Security+ 2.0 radio technology.

Compatible commercial remote controls use encrypted rolling-code communication to help protect against unauthorized copied radio commands.

Compatible accessories may include the LiftMaster 811LM commercial single-button remote.

Optional Battery Backup

Battery backup is not included as standard equipment with the LJ8950W.

The operator is compatible with the LiftMaster 485LM battery backup when properly installed.

Adding the compatible battery backup provides emergency powered operation during electrical outages and is also required to reach the higher applicable 850-lb door-weight rating.

Safety & UL 325

The LJ8950W is designed to comply with applicable UL 325 commercial operator safety requirements when properly installed with the required monitored entrapment-protection equipment.

Commercial operators require appropriate safety devices.

Depending on the installation, this may include:

• Monitored photoelectric sensors

• Monitored sensing edges

• Light curtains

• Other LiftMaster-approved entrapment-protection devices

Never bypass required safety equipment.

Chain Guard Requirement

A compatible chain guard is required in installations where the LJ8950W and exposed drive components are mounted below the height specified by LiftMaster.

LiftMaster identifies the 3950CGJ chain guard for applicable installations where the operator is mounted less than approximately 8 ft. above the floor.

Verify local codes and the current LiftMaster installation manual before installation.

Specifications

Compatibility

Use the LJ8950W only on a door that meets LiftMaster's application requirements.

Verify:

• Rolling door or grille construction

• Door width

• Door height

• Total door area

• Actual door weight

• Live-shaft or dead-shaft configuration

• Shaft diameter

• Door balance

• Available mounting space

• Sprocket arrangement

• Chain alignment

• Electrical supply

• Entrapment-protection requirements

• Daily cycle requirements

Do not order based only on door weight.

Not Intended For

The LJ8950W is generally not the correct choice for:

• Residential sectional garage doors

• Standard commercial sectional doors

• High-cycle industrial doors

• Continuous-duty applications

• Doors exceeding LiftMaster dimensional limits

• Improperly balanced rolling doors

• Damaged or binding doors

For residential sectional applications, see the LiftMaster 98022 or 98032.

For commercial sectional applications, see the LJ8900W.

Installation & Safety

Commercial rolling-door systems contain heavy components and can place substantial forces on shafts, chains, sprockets, brackets, and counterbalance assemblies.

Installation should be performed by a trained commercial-door technician familiar with:

• Rolling-door systems

• Shaft alignment

• Operator mounting

• Chain and sprocket setup

• Entrapment protection

• UL 325 requirements

• Limit programming

• Commercial door balance

Never attempt to use the operator to compensate for a door that is damaged, excessively heavy, binding, or improperly balanced.

Bottom Line

The LiftMaster LJ8950W is a compact light-duty commercial jackshaft operator designed specifically for smaller rolling doors and rolling grilles.

Choose the LJ8950W when you need:

• Rolling-door compatibility

• Wall-mount operation

• Built-in Wi-Fi

• myQ commercial connectivity

• Security+ 2.0

• Smooth DC operation

• Optional battery backup

• A light-duty commercial solution for fewer than 25 daily cycles

For a commercial sectional door, choose the LJ8900W instead.

For a residential sectional garage door, compare the LiftMaster 98022 and 98032.
