Mechanical pullers

Mechanical pullers for dismounting bearings and interference-fitted components

Mechanical pullers are essential service tools for the safe dismounting of bearings, belt pulleys, gears, sleeves, and rings with an interference fit. They enable the controlled removal of a component from a shaft or housing, reducing the risk of damage to fitted surfaces and shortening maintenance operation times.

Application and characteristics

In industrial plants, a mechanical puller proves its worth during overhauls of drives, gearboxes, pumps, and motors, as well as during routine inspections of production machinery. It is critical to match the design to the geometry of the component being removed and the available working space.

In practice, the most commonly used types are:

• two-arm pullers – convenient for working in confined spaces and with smaller components,
• three-arm pullers – providing uniform force distribution and more stable guidance during removal,
• internal and external pullers – for working from inside a housing or from the outside of a component, respectively,
• sliding-arm pullers – allowing rapid adjustment of the reach and spread to the diameter of the part being removed.

A well-selected puller allows dismounting to be carried out axially, without impacts or using brute force on the component. This translates to reduced part losses, faster repairs, and safer working conditions for the operator.

Key advantages

• Controlled dismounting – precise removal of bearings and interference-fitted components.
• Damage reduction – minimized risk of ruining the shaft, housing, and the dismounted part itself.
• Two-arm and three-arm variants – matching the tool to the task and the available space.
• Internal and external versions – ability to work in various mounting configurations.
• Faster service handling – shorter downtime and more efficient replacement of subassemblies.
