Hydraulic pumps

Hydraulic pumps for bearing mounting and dismounting

Hydraulic pumps are high-pressure tools used in oil injection technology during the mounting and dismounting of large interference-fitted components. They enable the precise delivery of pressurized oil into the fit zone, facilitating safe work with bearings, couplings, and other drivetrain subassemblies.

Application and characteristics of hydraulic pumps

In maintenance operations, a hydraulic pump is critical wherever force control and minimizing the risk of shaft or housing surface damage are required. In practice, pumps are used for:

• mounting and dismounting bearings using oil injection, which reduces friction and facilitates the movement of elements within the fit,
• powering hydraulic nuts to achieve a high, controlled axial force during bearing seating,
• operating in conjunction with hydraulic pullers during the dismounting of bearings, gears, or couplings.

The most important factor here is precise pressure control – it allows operations to be conducted smoothly, repeatably, and without sudden overloads. This is particularly crucial for large diameters and tight fits, where mechanical dismounting methods can be dangerous and inefficient.

Key advantages

• Safer mounting and dismounting – reduced risk of damage to fits and mating components.
• High working pressure – effective performance with large bearings and interference joints.
• Controlled process – smooth pressure regulation facilitates precise handling.
