The HySecurity MX001718 is a replacement upper and lower bearing and shim kit for select HySecurity and Nice HySecurity SwingRiser gate operator systems. It is commonly listed as Bearing and Shim Kit, Upper & Lower and SwingRiser Bearing and Shim Kit, Upper & Lower.
This kit is used in the SwingRiser post bearing area where the operators vertical tube and post assembly require proper bearing support and shim alignment. In the correct SwingRiser application, the upper and lower bearings help support the moving post/tube assembly while the shims are used to set the correct bearing fit and spacing.
Current listings describe MX001718 as including upper and lower post bearings made from UHMW material, sized 6.625 inches square by 3 inches, with a 90-degree cut for 4140 style tube. The kit is commonly listed as including 16 shims. Because SwingRiser bearing fitment depends on the post style, tube size, shim spacing, bearing wear, and parts diagram, MX001718 should be selected by exact HySecurity part number before ordering.
The MX001718 bearing and shim kit helps restore proper support and alignment in compatible SwingRiser post bearing assemblies. The UHMW bearings provide a low-friction wear surface, while the shims help center and space the bearing surfaces around the tube/post assembly.
If the upper or lower bearings are worn, loose, misaligned, cracked, missing shims, or installed with damaged fasteners, the gate may lift unevenly, bind, lean, chatter, rub, or place extra load on the SwingRiser hydraulic and structural components. Similar symptoms can also be caused by a bent tube, damaged post, worn fasteners, incorrect shimming, hydraulic cylinder issues, hinge or gate frame problems, or impact damage.
The HySecurity MX001718 is intended for select HySecurity / Nice HySecurity SwingRiser applications where this upper and lower bearing and shim kit is specified. Compatibility depends on the operator model, tube/post style, bearing size, bearing cut, shim stack, fasteners, and current HySecurity parts documentation.
Do not assume MX001718 fits every HySecurity SwingRiser, HydraSwing, HydraLift, SlideDriver, SlideSmart, SwingSmart, StrongArm, HydraWedge, Smart DC, Smart Touch, or SmartCNX operator. Bearing and shim kits should be matched by parts diagram, dimensions, and post/tube configuration.
HySecurity operators use several different bearing, shim, bushing, pin, and mechanical support parts. MX001718 should not be substituted for another bearing unless the parts diagram confirms it.
The bearing, shims, fasteners, tube, post, and structural alignment should be inspected together. Replacing the bearings without correcting a bent tube, worn post, loose hardware, or incorrect shim stack can cause repeat wear.
Shims are used to help set the correct bearing fit around the SwingRiser post/tube assembly. HySecurity SwingRiser documentation notes that when replacing bearings, shim packs may be forced into the space between the bearing and square post, and the bearing gap should be checked so the bearings remain centered with consistent clearance.
Do not remove or guess shim placement without checking the current service procedure. Incorrect shimming can leave the post loose, off-center, or binding, and can cause uneven wear or poor gate movement.
SwingRiser bearing replacement should be diagnosed with the complete mechanical and hydraulic system in mind. If the post bearing area is worn, inspect related components before deciding whether MX001718 is the only part needed.
MX001718 should be selected by HySecurity part number, SwingRiser model, bearing dimensions, tube/post style, shim requirement, and parts diagram. A UHMW bearing that appears similar may not match the correct square size, thickness, cut profile, shim setup, or 4140 style tube application.
If the original bearings failed due to impact, improper shimming, post damage, worn fasteners, misalignment, or gate structure problems, replacing only the bearing kit may not correct the root issue. Inspect the full SwingRiser post and gate assembly before returning the operator to service.

Before replacing MX001718, inspect the SwingRiser post, tube, fasteners, bearing seats, and alignment. If the tube is bent, the post is worn, or the bearing fasteners are loose or damaged, a new bearing and shim kit may not correct the problem by itself.
Pay close attention to shim placement and bearing centering. Improper shimming can leave the post too loose, too tight, or off-center, causing binding, uneven lift, or early bearing wear.
Disable the operator and secure the gate before servicing the SwingRiser bearing area. SwingRiser systems involve heavy gate movement, lifting force, pinch points, hydraulic load, and close-tolerance mechanical alignment.
When replacing the bearings, keep the bearing surfaces clean and compare the new parts to the original before installation. Shim the bearings according to the current HySecurity service procedure, verify the post remains centered, and check for smooth full travel before returning the operator to service.
SwingRiser bearing and shim replacement requires careful alignment. A qualified HySecurity gate technician should handle this repair if the gate is heavy, the post is damaged, the tube is bent, the bearing gap is unclear, or the operator has repeated binding or wear.
Do not bypass covers, guards, limits, monitored entrapment protection, photo eyes, safety edges, hydraulic controls, disconnects, or controller protections to make the operator run. The mechanical assembly, hydraulic system, and safety devices should be repaired correctly and fully tested before the operator is returned to service.
