HySecurity MX3960, Bushing, Hinge, HydraWedge
HySecurity MX3960 is a hinge bushing for select HySecurity HydraWedge SM50 wedge operator applications. Nice HySecurity HydraWedge SM50 parts documentation lists MX3960 as "Bushing, Hinge, HydraWedge" for HydraWedge SM50 models.
Current listings describe MX3960 as a primary hinge bushing for HydraWedge SM50 and as "BUSHING, HINGE, WEDGE, HW." This bushing is part of the wedge hinge and pivot hardware, where it helps support the hinge movement of the HydraWedge assembly. Because wedge hinge hardware is exposed to heavy loads, impact forces, weather, road debris, and repeated movement, MX3960 should be selected only after confirming the installed operator, hinge location, and HySecurity parts diagram.
What This Hinge Bushing Does
The hinge bushing supports movement at the HydraWedge hinge point. In the approved HydraWedge SM50 assembly, it works with the hinge hardware, wedge structure, spring piston components, hydraulic cylinder, and related pivot points to help the wedge move smoothly and stay properly supported during operation.
A worn, cracked, loose, seized, contaminated, or missing hinge bushing can contribute to rough wedge movement, side play, hinge noise, binding, uneven wedge travel, pin wear, hinge wear, or repeated hardware damage. Similar symptoms can also be caused by worn hinge pins, spring piston bushing wear, a damaged spring piston slide block, a weak or broken lift spring, bent wedge structure, hydraulic cylinder issues, debris in the wedge area, or impact damage.
Compatible With
Use HySecurity MX3960 only where the operator parts diagram, original bushing, or HySecurity documentation confirms this part number.
- Select HySecurity HydraWedge SM50 applications where MX3960 is listed as the hinge bushing.
- HydraWedge SM50 models where the parts diagram lists MX3960 as "Bushing, Hinge, HydraWedge."
- Repairs where the original hinge bushing is marked, listed, or cross-referenced as HySecurity MX3960.
- Applications where the hinge bushing location, hinge hardware, wedge pivot geometry, spring piston hardware, and wedge movement path match the HydraWedge SM50 parts diagram.
- Service repairs where diagnosis confirms the hinge bushing is worn, damaged, seized, loose, missing, or no longer supporting the hinge correctly.
Important Compatibility Warning
Do not order MX3960 based only on the words "hinge bushing." This part is listed for HydraWedge SM50 applications and should not be assumed to fit WedgeSmart DC, StrongArmPark DC, StrongArm, SwingRiser, HydraSwing, SlideDriver, SlideSmart, SwingSmart, or other HySecurity operators unless the parts diagram specifically lists MX3960.
HydraWedge SM50 includes several nearby hinge, spring piston, and wedge movement parts that are not interchangeable. MX3960 is the hinge bushing. The spring piston bushing, slide block, piston pin, lift spring, hydraulic cylinder, proximity switch, and LED wedge light are separate parts.

Technician Note
Before replacing MX3960, inspect the hinge area, hinge pin or pivot hardware, wedge plate movement, spring piston bushing, spring piston slide block, piston pin, lift spring, hydraulic cylinder mounting points, and any debris or impact damage inside the wedge assembly. A worn hinge bushing may be part of a larger hinge or wedge alignment problem.
If the hinge bushing is worn because of binding, impact, corrosion, debris, lack of service, bent hinge hardware, or a misaligned wedge plate, replacing only the bushing may not correct the problem. Check the surrounding hardware so the replacement bushing is not damaged prematurely.
Before Ordering, Confirm
- The required part number is MX3960.
- The operator is a HySecurity HydraWedge SM50 application where the parts diagram lists MX3960.
- The repair requires the hinge bushing, not the spring piston bushing, slide block, lift spring, piston pin, hydraulic cylinder, proximity switch, or LED wedge light.
- The hinge bushing location, hinge pin or pivot hardware, wedge movement path, and mounting geometry match the HydraWedge SM50 parts diagram.
- The related MX3956 spring piston bushing, MX3958 slide block, MX3959 piston pin, MX3957 lift spring, and hydraulic cylinder hardware have been inspected for wear.
- The wedge hinge area and wedge frame are not bent, binding, cracked, or damaged from impact.
- The package includes the expected hinge bushing, or any required hinge pins, clips, washers, grease fittings, or hardware are ordered separately if needed.
- The operator has not been modified with non-standard hinge, spring piston, or wedge components.
Installation and Service Notes
- Disconnect and secure operator power before servicing HydraWedge SM50 hinge or wedge hardware.
- Secure the wedge assembly before removing hinge, spring piston, or hydraulic components.
- Do not work under or around an unsupported wedge plate, hinge assembly, or spring-loaded hardware.
- Use caution around hydraulic cylinder hardware, hinge points, spring-loaded components, and pinch points.
- Keep hinge bushing surfaces, pins, washers, clips, and mounting hardware clean during service.
- Do not substitute similar-looking hinge bushings unless the parts diagram confirms fitment.
- After installation, verify smooth wedge movement, proper hinge support, correct spring piston travel, hydraulic operation, proximity switch response, and all required safety devices.
Professional Advisory
HydraWedge SM50 hinge bushing and wedge hardware service should be handled by a qualified gate technician when the repair involves heavy wedge plates, hinge points, hydraulic cylinder movement, spring-loaded hardware, impact damage, proximity switch alignment, or unknown prior modifications. Do not bypass controller protections, proximity switches, limit controls, stop circuits, access control safety inputs, photo eyes, safety edges, or any required safety devices to keep the operator running.
