Handwheel GN 322.5-125-K12-D-ZI Z009158

GN 322.5 Handwheels – Precision and Safety in Machine Operation

GN 322.5 handwheels are components used for manual control of machines and devices. Made of aluminum, they are characterized by high durability and corrosion resistance. The design with needle bearing ensures smooth and precise operation, minimizing friction and wear. They are ideal components for applications requiring frequent and accurate adjustment of operating parameters.

Design and Functionality

GN 322.5 handwheels are available in various versions, including with a rotating handle (type D) for ergonomic transfer of fast adjustment movements and with a coupling mechanism by pulling (ZI) or pushing (DR). The ZI version, featured in the described model (GN 322.5-125-K12-D-ZI), allows for safe coupling and decoupling of the shaft by axially pulling the wheel. When released, the wheel automatically disconnects due to spring force, increasing safety. The wheel body is made of aluminum, and the hub is precision machined, guaranteeing high accuracy and stability. The wheel rim is turned and polished to a shine, while the remaining surfaces are sandblasted to a matte finish, providing an aesthetic appearance and user comfort.

Applications and Benefits

GN 322.5 handwheels find wide application in various industries, including:

• Machine Tools: Precise control of the movement of worktables and other machine elements.
• Industrial Automation: Adjustment of operating parameters of automated devices.
• Laboratory Equipment: Accurate positioning of optical and mechanical elements.
• Packaging Machines: Control of the speed of conveyor belts and other packaging processes.
• Industrial Installations: Regulation of media flow in valves and throttles.

Thanks to their design, GN 322.5 wheels provide:

• Safety: The coupling mechanism minimizes the risk of accidental machine or device activation during adjustment.
• Precision: High quality workmanship and precise bearing ensure accurate motion control.
• Ergonomics: The rotating handle (in version D) makes it easy to operate the wheel even during intensive work.
• Durability: High-quality materials guarantee a long service life even in harsh operating conditions.
• Versatility: A wide selection of diameters and coupling types allows you to adapt the wheel to specific application needs.

Mounting and Compatibility

GN 322.5 handwheels are compatible with standard GN 000.5 coupling sets with needle bearing and have a P9 DIN 6885-2 keyway for secure seating on the drive shaft. Installation is simple and intuitive, and thanks to the precise workmanship, it does not require additional adjustments or adaptations - simply mount the appropriate coupling set and secure the shaft with GN 184 retaining washers (available separately).
