FCQ Type Gas Spring Plate - Upper Groove Fixed

This FCQ type gas spring plate is used as a fixed mounting interface in injection molded end-product assemblies that rely on repeatable gas spring positioning. By locking into the upper groove of the gas spring body, it helps maintain consistent stroke alignment and reduces variation during assembly.

• Cabinet and appliance lift systems: Ideal for upper-groove fixed layouts where the mounting must stay stable across repeated open/close cycles.
• Automotive interior/trim panels: Supports clean alignment in modular spring stacks so trim components mount without twist or preload inconsistency.
• Industrial access covers: Suitable where fixed square mounting improves positional consistency and helps ensure predictable closure feel.

The variant is suited for these applications because the groove-fixed design provides stable location in the gas spring interface, supporting reliable downstream alignment in the molded housing and trim parts.

The provided specifications include the outer diameter range (D = 45 or 50 mm), but no steel grade, heat treatment, hardness, or coating details are stated for this particular plate variant. Therefore, material performance claims such as HRC hardness, nitriding, or quenched-and-tempered microstructure cannot be verified from the given data.

In gas-spring mounting plates, engineers typically select steels or surface treatments that balance wear resistance (against groove friction and assembly handling) with toughness (to avoid chipping under shock loads). If your project requires specific durability, request the exact material datasheet and heat treatment condition for the FCQ model tied to series code 110110589139.

To select the correct plate, match the required interface geometry to the specified outer diameter (D). This series is specified with two options: D = 45 mm and D = 50 mm. Choose the diameter that corresponds to the groove and clearance requirements of your gas spring body and the mating mounting layout in the assembly.

• Upper groove fixed alignment: Confirm that your gas spring’s upper groove dimensions and tolerances accept the groove-locking square plate form factor without interference.
• Fit and clearance: If your design uses molded features around the mounting, verify stack-up tolerance so the plate seats fully while avoiding binding.
• Configurable vs fixed: The mounting concept is fixed as “upper groove fixed” (FCQ), while the selectable dimension you have from the provided data is the outer diameter (45 or 50 mm).

After diameter selection, validate assembly fit using your system’s groove-to-housing clearance and any required positional tolerances for repeated alignment.
