HySecurity MX4168, Bearing, Scissor Joint 2
The HySecurity MX4168 bearing is used at the scissor joint 2 position in HydraWedge SM50 hardware. In a wedge barrier, pivot bearings are exposed to repeated heavy loading as the plate raises and lowers. Correct bearing fitment helps maintain alignment, reduce friction, and prevent damage to adjoining scissor arms, pins, and bushings. If this bearing is being replaced due to wear, the related joint hardware should be inspected at the same time, including MX4166 bushings, MX4167 scissor joint 1 bearing, spring strut hardware, and lift-assist spring components. The exact location should be confirmed with the HySecurity exploded view before ordering.

- Check surrounding parts for wear or damage before replacing only one component.
- For hydraulic, high-load mechanical, or electrical repairs, use a qualified gate technician.
Professional Advisory
Gate and barrier equipment can move with significant force and may contain stored mechanical energy, hydraulic pressure, or live electrical circuits. Do not bypass safety devices, guards, sensors, or interlocks. If the system has uncontrolled movement, missing guards, damaged wiring, hydraulic leakage, or uncertain compatibility, stop operation and have the equipment inspected by a qualified technician.
Product Questions and Answers
What is MX4168 used for?
MX4168 is used as the scissor joint 2 bearing in select HydraWedge SM50 linkage assemblies.
Is MX4168 interchangeable with MX4167?
Do not assume interchangeability. MX4167 and MX4168 identify different scissor-joint bearing positions.
What should be checked when replacing this bearing?
Inspect the mating pin, bushings, scissor arms, spring strut hardware, and nearby bearing locations.
Can this bearing fix all wedge lifting issues?
No. Lifting issues can also involve hydraulic pressure, cylinders, valves, springs, linkage alignment, or controller faults.
Is this for SlideSmart HD?
