The PMK 81100 / 81200 series are cylindrical roller thrust bearings designed for very high axial load capacity in one direction. These bearings are optimized for applications demanding high stiffness, high axial load support and minimal axial displacement, such as presses, heavy machinery and large-scale spindles.

Key benefits

• Very high axial load capacity: engineered to carry substantial axial loads with cylindrical rollers distributing load over a large contact area.
• High stiffness: minimal axial displacement under load, suitable for heavy-duty machines and axial preload applications.
• Simple assembly: one-direction thrust format with robust design simplifies mounting in large axial-load environments.
• Long life: precision raceways and appropriate lubrication paths support heavy duty continuous operation.

Applications

• Presses and heavy-duty manufacturing equipment.
• Large spindle support where axial thrust dominates (e.g., grinding spindles, machine tool axes).
• Wind turbine yaw or blade bearing support (in appropriate sizes).
• Any axial-only heavy load application requiring a robust bearing solution.

Typical technical highlights

• Cylindrical roller set optimized for thrust loads (one direction).
• Robust raceway design for high load capacity and long service life.
• Suitable for axial preloading and high precision alignment.
• Can be combined with other bearings (externally) for radial load support where required.
