psl® tapered roller bearings

In our psl® tapered roller bearings, the tapered rollers run in designated cages on the raceways. They are ideal for simultaneously absorbing radial and axial loads. The point on the bearing’s axis where contact occurs ensures a low-friction operation and correct rolling.

By means of their large bearing distance, the tapered roller bearings’ forces are well absorbed, thus guaranteeing rigid shaft guidance. The fact that they can be separated makes them easy to assemble and to adjust.

Our products

Single-row tapered roller bearings

The single-row tapered roller bearings can transmit both radial and axial forces. The axial capacity depends on the size and the contact angle. The single-row tapered roller bearings can only transmit axial loads in one direction, thus, they are used in pairs. The axial clearance or the pre-loading must be set accordingly during assembly. The size of the axial clearance or the pre-loading is selected based on the operating conditions, the size and type of bearing, and bearing rigidity requirements.

Current manufactured size: Ø d = 200 to 3000 mm; max. Ø D = 3400 mm

Typical applications: Cranes and lifting devices, Wind energy, Gear manufacturing

Double-row tapered roller bearings

The double-row psl® tapered roller bearings are rigid bearing which high loading capacity which are perfect for the absorption of radial and axial loads. By adjusting the axial clearance and the preload, the shaft can be guided in both directions.

The main application areas for double-row tapered roller bearings include heavy engineering and the automotive industry.

Current manufactured size: Ø d = 200 to 1440 mm; max. Ø D = 1918 mm

Typical applications: Cranes and lifting devices, Wind energy, Smelting works engineering, Gear manufacturing, Raw material extraction and processing

Multi-row tapered roller bearings

The multi-row tapered roller bearings are best suited for absorbing large radial forces. They are used worldwide as bearings for mills in metallurgical facilities. The type of bearing is designed for low to medium rolling speeds. Thanks to the design of four-row psl® tapered roller bearings, the high axial loads typically found on radial loads can also be absorbed. Thus, in general, there is no longer a need for a separate axial bearing.

Advantages:

  • Fewer bearing parts ensure an easier assembling process

  • Lower wear and higher service life thanks to a more favourable distribution of the load across the four roller rows

Current manufactured size: Ø d = 200 to 660 mm; max. Ø D = 1070 mm

Typical applications: Smelting works engineering

High precision crossed tapered roller bearings

High precision psl® crossed tapered roller bearings allow accommodation both radial loads and axial loads as well as tilting moments. Due to excellent machining and tapered shape of rolling elements the bearings fulfil requirements for high running accuracy and smooth operation without slipping even at high speeds.

The bearings are delivered as unassembled units with strictly defined order of individual rollers in raceways when assembling. An operational preload in raceways is adjustable during final installation into the machine.

The psl® crossed tapered roller bearings are especially suitable for highly demanding rotary table installation in machine tools.

Current delivery range starts from ø d = 330,2 up to 2100 mm; ø D = from 457,2 up to 2430 mm.

Typical applications: Turntables in machine tools
