Handwheel GN 322.4-140-K12-D-DR Z009125

Handwheels – Precision and Functionality in One Element

The GN 322.4 handwheel is a reliable control element, widely used in machines and equipment requiring precise adjustment. Made of aluminum, it is characterized by high durability and resistance to loads. The wheel's construction, based on plain bearing, ensures smooth and comfortable operation. This model, designated GN 322.4-140-K12-D-DR, combines solid workmanship and thoughtful design.

Construction and Principle of Operation

The GN 322.4 handwheel is distinguished by the possibility of coupling by pushing (DR version), which ensures quick and reliable activation of the mechanism. The wheel body is made of aluminum, and the hub has been precisely machined, guaranteeing high accuracy and stability during operation. The wheel rim is turned with high precision – radial and axial runout does not exceed 0.4 mm – and then polished to a high gloss. The remaining surfaces are sandblasted to a matte finish, providing an aesthetic appearance and comfortable use. The GN 000.4 coupling set with plain bearing is made of nitrided steel, which increases its strength and wear resistance.

Applications in Practice

The GN 322.4 handwheel is ideal for applications requiring manual adjustment of the position of machine elements, such as:

• Machine tools: Precise positioning of cutting tools.
• Measuring devices: Smooth adjustment of the position of measuring heads.
• Industrial automation: Control of valves and dampers in automation systems.
• Specialized machinery: Adjustment of operating parameters in machines dedicated to specific production tasks.
• Furniture structures: Adjustment of the height of countertops or other equipment elements (e.g., desks).

Thanks to its versatility, the GN 322.4 wheel finds application both in heavy industry and in more precise laboratory or research applications. Installation is simple thanks to the P9 DIN 6885-2 keyway facilitating correct seating on the shaft. Additionally, the use of GN 184 locking washers allows securing the axial displacement of the wheel during operation.
