Adjustable lever GN 300-30-M4-20-SR Z044473

Universal locking lever for precise locking

The GN 300-30-M4-20-SR locking lever is a robust component for quick and reliable locking of positions, ideal for both precision machines and devices requiring frequent adjustment. The zinc die-cast construction guarantees durability, and the choice of finishes ensures that the lever will match the aesthetics of any device.

Construction and materials

The lever is made of zinc die-cast, which provides good resistance to corrosion and mechanical damage. Various surface finish options are available:

• Epoxy resin coating – available in black (RAL 9005), orange (RAL 2004), red (RAL 3000), silver (RAL 9006) and graphite (RAL 9011). The matte finish provides comfortable use and an aesthetic appearance.
• Chrome finish – for applications requiring high corrosion resistance and an elegant appearance.
• Uncoated variant – polished, for specific industrial applications.
• Black oxidized steel – used on the threaded pin and connecting screw, providing a durable connection and abrasion resistance.

The lever mechanism is based on a multi-lobe design, which allows for precise setting and locking in the desired position. A return spring automatically engages the teeth when the lever is released, ensuring setting stability. The connecting screw made of black oxidized steel further strengthens the construction.

Application and benefits

GN 300 levers are widely used in:

• Production machines and equipment – for locking elements in specific positions during processing or assembly.
• Laboratory equipment – for precise positioning and locking of optical or mechanical elements.
• Medical equipment – where quick and reliable position adjustment is required.
• Metalworking - as an element locking moving parts of the machine.

Advantages:

• Precise locking: The multi-lobe mechanism ensures accurate setting and stable locking of the position.
• Wide selection of finishes: Possibility to match the color and material to the requirements of the application.
• Durability: Zinc die-cast and steel components guarantee a long service life even in harsh working conditions.
• Easy installation: The threaded pin allows for quick and easy installation of the lever in a hole of the appropriate diameter.
• Versatility: Suitable for many different industrial and laboratory applications.
