Hook and impact spanners for bearing nuts

Spanners for bearing handling are service tools that enable precise mounting, dismounting, and adjustment of bearing nuts on shafts, housings, and sleeves. In practice, a hook spanner and an impact spanner allow for the safe transmission of tightening torque without the risk of damaging the nut, thread, or fitted surfaces.

Application and characteristics

A hook spanner is designed for working with bearing nuts (e.g., KM, KMT types) used when seating bearings on adapter sleeves and withdrawal sleeves, as well as during clearance adjustment and assembly locking. It ensures a secure grip and force control, particularly in the servicing of gearboxes, motors, pumps, and bearing assemblies in maintenance operations.

Depending on your needs, you will find fixed-size spanners (e.g., HN series) as well as adjustable hook spanners with a wider regulation range (e.g., HNA), which facilitate handling various nut diameters within a plant. For larger nuts and heavier applications, an impact spanner (e.g., industrial types) is utilized, adapted for controlled hammer blows on its striking surface – without slippage and without destroying the nut edges.

Key advantages

• Secure grip on the bearing nut – reduced risk of damage to the nut and mating components.
• Precise adjustment and locking – facilitates the correct seating of bearings on sleeves and in housings.
• Tailored to the application – fixed spanners (HN) for specific sizes and adjustable spanners (HNA) for working across different ranges.
• Safe operation in harsh conditions – an impact spanner for large nuts and connections requiring higher force.
• Ergonomics in servicing – more convenient work during machinery inspections and overhauls, leading to shorter downtime.
