The HySecurity MX4167 bearing is identified as the scissor joint 1 bearing for the HydraWedge SM50. The scissor linkage in a wedge barrier is a high-load mechanical area that must stay aligned for reliable raising and lowering. A worn bearing can create play in the linkage, side loading, metal dust, uneven movement, and accelerated wear on the mating pin or bushing. This part should be selected by the HySecurity parts diagram position, not just by size, because HydraWedge SM50 uses more than one scissor-joint bearing reference. During repair, technicians should support the wedge and linkage properly and inspect MX4166 bushing, MX4168 bearing, pins, and the lift spring for related wear.
Replacement bearing for scissor joint 1 in select HydraWedge SM50 linkage assemblies.
Compatibility is based on currently available HySecurity and distributor part references. Always verify the exact operator model, serial range, configuration, and parts diagram before ordering.

This is an OEM-style HySecurity replacement part. Similar-looking HySecurity parts may differ by operator family, generation, voltage, harness length, handedness, or mechanical position. Use the original part number and the operator parts diagram as the final fitment check.
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.
MX4167 is listed as scissor joint 1 bearing, while MX4168 is listed as scissor joint 2 bearing. Do not swap them unless the parts diagram confirms the location.
MX4167 is commonly associated with HySecurity HydraWedge SM50 scissor-linkage service.
Replace it for excessive play, noise, binding, visible bearing damage, or during a scissor linkage rebuild.
Yes. A new bearing should not be installed onto a worn pin or into damaged surrounding linkage.
No. Some listings use confusing category labels, but the supported product description identifies MX4167 as a scissor joint 1 bearing.
