Thrust roller bearing
Most of Thrust roller bearings are separable, which make it very convenient to mount and dismount. This type of bearings has high rigidity and takes up little space, so it could carry heavier axial load and a certain amount of impact loads. They are mainly used in applications where the load carrying capacity of thrust ball bearing is inadequate. Thrust roller bearings are divided into cylindrical roller thrust bearings, taper roller thrust bearings, spherical roller thrust bearings, and needle roller thrust bearings by different structures.

Product Description of Thrust roller bearing
- There are several types of thrust bearings, each with its own strength.
- The unique bearings offer different performance and load capacity.
- Thrust ball bearings are used in industries such as aerospace, chemical industry and utilities.
- Thrust roller bearings are used in agriculture and other areas where high load capacity is required.
- Thrust bearings are also commonly used in automotive and marine applications.
- They are used in automobiles because the forward gears in modern automobile transmissions use helical gears, which, while helping to smooth and reduce noise, generate axial forces that need to be handled.
- Thrust bearings provide high reliability
- Provide high load capacity in harsh environments
- Easy to install – shaft and housing washers can be mounted separately
- Wide variety available
Availability - Roller thrust bearings
- have a higher load
- carrying capacity than
- ball thrust bearings.
- Higher speed
- applications require oil lubrication.
- Axial cylindrical roller bearings
These are thrust bearings that contain cylindrical rollers. They can only carry axial loads, but they are suitable for heavy loads and have a high axial stiffness.
The cage is machined brass. - Thrust tapered roller bearings
These thrust bearings containing tapered rollers are available in two types. - TT bearings with a retaining edge on the seat ring can guide the shaft precisely in the radial direction, while TTF bearings without a retaining edge on the seat ring can tolerate some eccentricity during operation.
- Axial spherical roller bearings
These are thrust bearings that contain convex rollers. They are self-aligning and are unaffected by mounting errors or shaft deflection. - In addition to the original type, an E type with pressed cage for high load capacity is also available. Their bearing numbers are suffixed with E.
- For horizontal shafts or high-speed applications, machined brass cages are recommended.
- Consult NSK for details. oil lubrication should be used even at low speeds because of several difficult lubrication areas, such as the area between the roller head and the inner ring retainer, and the sliding surface between the cage and the guide bush. The original type of cage is machined brass.
- Needle roller bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. This type of roller is called a needle roller.
- Needle roller bearings are equipped with thin and long rollers (roller diameter D≤5mm, L/D≥2.5, L is the length of the roller), so the radial structure is compact, especially suitable for the support structure with limited radial installation size .
- Thrust roller bearings are available with cylindrical rollers or spherical rollers and carry only axial loads, but they are suitable for heavy loads and have high axial stiffness.
- Spherical thrust roller bearings contain convex rollers and are self-aligning and are not subject to any effects of mounting errors or shaft deflection.
- Standard cages are machined brass, with Type E available with pressed cages to achieve high load capacity.
Application of Thrust roller bearing

FAQ
Due to their internal design, ball bearings cannot usually be disassembled down to the component level; therefore, they cannot usually be refurbished.
Solid base shells are manufactured without cavities and fillers; they are stronger than hollow bases, and there are no traps for bacteria and fungi to grow. In the thermoplastic shell, the sturdy base will not break under steam or high-pressure washing. The hollow base saves material and weight to reduce costs. Some people use epoxy resin to backfill the hollow base to eliminate the trap of bacteria breeding, but this will not increase the strength, will cause the installation surface to be uneven, and water will seep between the shell and the filling material, causing cracking.
Use particularly thermally stable bearing rings, larger internal clearance (C4), specially selected lubricants that will not decompose at high temperatures, and zinc anodized flinger. There are two basic versions of our high temperature bearings. The suffix “C4HR5” represents the bearing that can withstand 400°F, and the suffix “C4HR23” represents the bearing that can withstand 450°F.
For critical applications such as pulp and paper processing, printing and packaging, material tearing can cause expensive downtime due to excessive torque and vibration.
The two biggest factors affecting the starting and running torque of the bearing are the seal design and lubricant selection. The shaft and bearing seat fit, component accuracy and surface finish, and retainer design also have some influence.
In higher speed applications, non-contact sealing devices are usually required to minimize operating torque and heat generation, so oil baffle rings and secondary sealing devices are usually required. Flowing oil lubrication systems are usually the best solution.
After proper installation, most seated bearings only need to be relubricated regularly with a small amount of grease and checked to ensure that they operate at low temperatures, quietness, and sufficient accuracy.
This depends on many factors, such as the application’s load conditions, operating speed, duty cycle, temperature, and operating environment. The technical information section of this website provides some basic information. Our engineers can help you determine more specific theoretical life calculations.
When noise and/or operating temperature increase or operating accuracy decreases, bearings should be replaced.
Lubricant of choice
Lubrication joint type or location
Sealing materials and design options
Dimensions, suitable for housing or insert
Fixing screw options
Paint the shell in any color
Too little or too much lubricant
Incorrect lubricant type
Poor bearing installation
Improper internal clearance
Excessive load and/or speed
Extreme temperature
Pollution
Movement between mounting surfaces
The noise emitted by the bearing may be caused by a combination of one or more factors, such as insufficient working clearance, excessive working clearance, changes in working clearance due to temperature, damage to the contact area, contamination, inappropriate lubricants or The raceway is damaged.
Lubricants have five basic functions for bearings:
Reduce friction
Reduce wear
Reduce temperature rise
Minimize corrosion
Seal contaminants
We do not recommend mixing grease. Mixing incompatible greases will cause the mixture to harden, preventing it from releasing any oil. Mixing incompatible greases can also soften the mixture, which releases all the oil. In either case, the mixture will not be able to properly lubricate the bearing. We strongly recommend using the same type of grease originally provided with the bearing.
