Thrust roller bearings Manufacturers online

Thrust roller bearings are roller bearings that have been specially developed to support axial forces, i.e. forces along the shaft axis.

In contrast to radial bearings, which mainly bear radial forces, thrust bearings are designed to support loads in the longitudinal direction.

Below you will find the mode of operation, the types of thrust roller bearing, as well as an overview of their use and their advantages:

How thrust roller bearings work:

Inside are rollers matched to the type of load, which are arranged between two bearing washers. When an axial load is applied, these rolling elements roll between the raceways of the bearing washers and distribute the force evenly. Due to the large contact surface of the rollers compared to balls, thrust roller bearings can bear particularly high loads.

Depending on the design, thrust roller bearings can:

1. Only support axial forces in one direction, e.g. axial cylindrical roller bearings.
2. Support axial forces in both directions. Design with two bearing units.
3. Or additionally withstand radial forces, e.g. axial tapered roller bearings.

Thanks to their design, they are mainly used where high compressive forces occur, while rotational speeds tend to be low to medium.

Types of thrust roller bearings:

Thrust roller bearings differ depending on the roller geometry and application requirements:

1. Thrust cylindrical roller bearings:
   They use straight cylindrical rollers and offer very high rigidity.
   They are particularly suitable for high axial loads at low speeds.
2. Thrust needle roller bearings:
   This variant uses particularly slim rollers (needles), which enables them to have a space-saving design.
   They are suitable for applications with limited installation space, but not for extreme loads.
3. Thrust tapered roller bearings:
   With tapered rollers, they can support both axial and conditional radial forces.
   They are therefore versatile and often found in applications with combined loads.
4. Spherical thrust roller bearings:
   They have curved rollers that can self-align.
   This makes them insensitive to misalignment and particularly suitable for inaccurate or elastic bearing arrangements.

Use of thrust roller bearings:

Thrust roller bearings can be found in many industrial sectors where high axial forces occur:

1. Mechanical engineering:
In presses, rolling mills or heavy-duty gearboxes where large compressive forces act.

2. Automotive industry:
In gearboxes, clutches and differentials.

3. Energy technology:
In turbines, generators or wind turbines where combined loads occur.

4. Construction and materials handling:
In crane systems or construction machinery that have to support heavy loads.

Advantages of thrust roller bearings:

• High load carrying capacity: Due to the large contact surface of the rollers, they can absorb very high axial forces.
• Versatility: Depending on the design, they are suitable for pure axial loads or combined axial and radial loads.
• Long service life: With correct lubrication and maintenance, they are very robust.
• Self-aligning (for barrel roller bearings): They can compensate for misalignment and shaft deflection without suffering damage.
• Compact design: Needle roller variants in particular offer a space-saving solution where installation space is limited.

Thrust roller bearings are indispensable machine elements when it comes to safely absorbing axial forces. With their different designs, they cover a wide range of applications - from space-saving needle roller bearings to heavy-duty barrel or tapered roller bearings. Their advantages lie in their high load capacity, versatility and reliability, which makes them a key component in many industrial and technical sectors.

Here are the most important criteria to consider when purchasing thrust roller bearings.

Thrust roller bearings are heavy-duty machine elements that are used in many branches of industry to reliably absorb large axial forces. Whether in presses, gearboxes, wind turbines or heavy machinery - their performance is often crucial for operational safety. When purchasing, it is therefore not enough to simply compare the price. Quality, accuracy of fit and reliability must be at the forefront, as incorrect bearing selection or inferior designs can lead to downtime, high follow-up costs and safety risks.

• Before obtaining quotations, the specific requirements of the application must be clearly described:
• What axial and, if applicable, radial forces will occur?
• What speeds are achieved?
• Are there special requirements in terms of rigidity, temperature resistance or service life?
• Does the bearing have to support one-sided or double-sided loads?
• The choice of suitable bearing type is crucial:
• Thrust cylindrical roller bearings for very high axial loads at low to medium speeds.
• Thrust needle roller bearings for small installation spaces and moderate forces.
• Thrust tapered roller bearings for combined axial and radial loads.
• Spherical thrust roller bearings for cases where misalignment or shaft deflection can occur.
• Professional purchasers should pay attention to the following points:
• High quality steels, e.g. bearing steel, for strength and wear protection.
• Heat treatment and precise manufacturing for a long service life.
• Corrosion protection if the bearing is operated in a damp or aggressive environment.
• Manufacturer certificates, e.g. ISO 9001, IATF 16949 for the automotive industry.
• Dimensional accuracy is crucial for function:
• Bearings and mating parts must be precisely matched.
• Excessive tolerances lead to vibrations or incorrect loads.
• Too tight a fit can make assembly and disassembly more difficult.
• The supplier should therefore provide precise dimensional data and tolerance classes.
• Axial roller bearings require reliable lubrication to minimize wear:
• Clarify whether the bearing is supplied greased, oiled or without lubrication.
• Check whether lubrication grooves, lubrication holes or seals are present.
• Consider relubrication requirements and maintenance intervals.
• A professional supplier should provide more than just standard products:
• Provide technical advice on selecting the right bearing.
• Availability of special designs for special applications.
• Documentation such as drawings, data sheets, test certificates.
• Delivery reliability and spare parts supply over long periods of time.
• When purchasing axial roller bearings, the purchase price should not be the only consideration:
• Longer service life and lower maintenance costs reduce overall costs.
• Cheap products without proof of quality often lead to a higher risk of failure.
• Framework agreements or bulk purchases can improve cost planning.
• Compliance with environmental and legal standards is also playing an increasingly important role:
• Materials should be REACH and RoHS compliant.
• Manufacturers with sustainable production processes offer additional security.
• Traceability of every batch is mandatory for safety-critical industries!

The purchase of thrust roller bearings requires more than just the procurement of a standard part. A clear requirements analysis, the selection of the right design, high-quality materials and a competent supplier with proof of quality assurance are crucial. Anyone who buys solely on the basis of the lowest price risks failures and high follow-up costs. Careful selection, on the other hand, guarantees operational reliability, durability and cost-effectiveness - and therefore a decisive competitive advantage.
