Customization Services
Material Combinations: Flexible selection of body, ball, and spring materials；
Dimensions & Parameters: Adjustable body diameter, ball size, and spring force to meet non-standard requirements
Automated production line indexing, precision mold clamping, heavy machinery buffering, etc.
The Advantage of GN611 Long Stroke Spring Plunger:
Long range adaptability:
Supports 1.5-40mm expansion and contraction, used for positioning with large fluctuations in workpiece thickness.
Dual level load design:
Ultra light loading type: Min. Load (0.1N-1.7N)&Max. Load (0.3N-13N)
Light loading type: Min. Load (0.5N-28N)&Max. Load (1N-118N)
Environmental resistance:
Stainless steel version is resistant to acidic and alkaline environments.
Ball Plunger Spring Loaded Key points for installation and maintenance
Pre installation inspection
Confirm that the plunger model matches the installation hole size, and check that the spring is not deformed or stuck.
Clean the installation holes and surrounding areas, remove oil stains and debris, and ensure that the contact surface is dry and flat.
Snap on installation
Align the plunger vertically with the mounting hole (with the groove facing outward), and apply pressure evenly with your thumb until the buckle locks with a "click" sound.
Do not use hammers or hard objects to strike, to avoid plastic buckles breaking.
Notes:
Fault handling
Stuck without resetting: Remove the plunger and check for foreign objects embedded; If the spring is corroded, replace it as a whole.
Unexpected detachment: Confirm that the installation hole is worn;
