Linear 2500-2252-UPS 1/3 HP 115V Motor with Harness for BGU-12-311 Operators
The Linear 2500-2252-UPS is a replacement 1/3 horsepower 115V motor assembly supplied with a harness for select Linear / OSCO barrier gate operators. This style of motor is part of the drive system that lifts and lowers the barrier arm through the operator mechanism. The harness is a key part of the assembly because it helps the motor connect to the correct control and power circuit without field-splicing the wrong leads. It is commonly used when a motor has failed electrically, has worn bearings, has heat damage, or no longer provides enough torque for the barrier gate system. Because barrier gate operators can look similar but vary by arm length, cabinet, voltage, control box, and production generation, the original motor label and the BGU parts diagram should be checked before ordering.

Use this section as a fitment guide, not a substitute for the operator parts diagram. Linear and OSCO service parts can vary by production date, voltage, phase, horsepower, enclosure, control package, and connector layout.
- Confirmed in supplier references for Linear BGU-12-311 barrier gate operators.
- Select Linear / OSCO BGU series barrier gate operator configurations using a 1/3 HP 115V motor with matching harness.
- May be associated with BGU barrier arm operators where the parts diagram calls for 2500-2252-UPS.
- Not automatically compatible with all BGUS, SG, or other Linear barrier operators.
- Verify model number, motor tag, voltage, harness connector, and mechanical mounting before ordering.

Technician Note
Do not select this motor only because the horsepower and voltage sound close. On barrier operators, the harness, mounting, and control package matter just as much as the motor rating.
Before Ordering
- Confirm the barrier operator model is BGU-12-311 or another supported model calling for this part.
- Match the original motor label to 2500-2252-UPS or a confirmed equivalent.
- Compare harness connector, wire count, and mounting pattern.
- Inspect arm balance, springs, gearbox, and linkage so a mechanical fault does not damage the new motor.
- Confirm all covers, safety devices, and barrier arm hardware are secure after service.
Important Ordering Warnings
- Not a universal BGU/BGUS/SG barrier motor.
- Do not modify harness wiring unless the manufacturer wiring diagram supports the change.
- Motor replacement on powered barrier equipment should be performed by a qualified technician.
Professional Advisory
For any high-voltage motor, drive, timer, or hardwired intercom service, use a qualified gate or access-control technician. After replacement, the complete system should be tested for normal operation, safe stopping, proper limits, and active safety devices.
Product Questions and Answers
Which operator is the Linear 2500-2252-UPS commonly linked to?
It is commonly referenced for the Linear BGU-12-311 barrier gate operator when the original parts diagram calls for this 1/3 HP 115V motor with harness.
Does the harness come with this motor?
Yes, this listing is for the motor with harness. The harness should still be compared to the original motor assembly before ordering.
Can this replace any 1/3 HP 115V barrier motor?
No. Horsepower and voltage are not enough to confirm fitment. The exact part number, harness, mounting, and operator model must match.
What can cause a new barrier motor to fail early?
A binding arm, incorrect spring balance, damaged gearbox, worn linkage, wrong voltage, or wiring fault can overload the motor and cause repeat failure.
Should I replace this part myself?
Electrical and mechanical barrier gate repairs should be handled by a qualified gate technician, especially when motor wiring or arm balance is involved.
