Types of Tapered Roller Bearing

32056 X Tapered Roller Bearing

32056 X single row tapered roller bearings are designed to accommodate combined radial and axial loads and provide low friction during operation.

KT921 Axial Tapered Roller Bearing

KT921 is an axial tapered roller bearing, mainly used to bear radial and axial combined loads, with high load capacity and good rigidity.

KT921 Axial Tapered Roller Bearing
331081 A Bearing | TQO Type

331081 A Bearing | TQO Type

331081 A is a four-row tapered roller bearing. The main size of per one is 501.65*711.2*520.7 mm/662 kg. It can accommodate combined heavy radial and axial loads at low to moderate speeds.

351988 Bearing

351988 double row tapered roller bearing is separable bearings that cannot be self-maintaining. In addition to radial forces, high axial forces can also be tolerated in both directions due to the symmetrical arrangement of the bearings.

Common Materials of Tapered Roller Bearing

GCr15: Good overall performance. After quenching and tempering, the hardness is high and uniform, and the wear resistance and contact fatigue resistance are high. Good performance on machining.

 

GCr15SiMn: GCr15SiMn steel is a modified steel that appropriately increases the content of silicon and manganese on the basis of GCr15. It has good harden ability, wear resistance, and elastic limit, with better wear resistance than GCr15.

GCr18Mo

It is a new type of high hardenability bearing steel, belonging to the high carbon chromium bearing steel series. Compared with GCr15 and GCr15SiMn, the chromium content is increased, appropriate molybdenum is added, and the lower bainite isothermal quenching heat treatment process is used to obtain the lower bainite structure and higher residual austenite content, with higher impact toughness and fracture toughness.

G20CrNiMo

It is an alloy carburized steel. After carburization treatment, the surface has a relatively high hardness, wear resistance, and contact fatigue strength, while retaining good toughness at the core, which can withstand high impact loads. Good hardenability and high strength.

G20Cr2Ni4A

It is a high-quality alloy carburized steel with high surface hardness, wear resistance, and contact fatigue strength after carburization treatment. At the same time, it retains good toughness at the core and can withstand high impact loads.

 

Functions of Tapered Roller Bearing
 

Increased load capacity: These bearings are capable carry higher loads than other types of bearings, due to their unique design and geometrical structure.

 

Improved durability: These bearings are designed to withstand heavy-duty use, and as such, they are often found in industrial and automotive applications.

 

Reduced friction: The design of these bearings helps to reduce friction, making them more efficient than other types of bearings.

Low maintenance

These bearings require little maintenance, and can often last for many years without needing to be replaced.

 

Operational Reliability

The roller bearings are designed in such a way as to operate with smoothness on the contact surfaces without any hassles of wear and tear in any kind of machinery. This ensures improved operation and performance.

 

Low Noise and Vibration

These are efficiently designed in a way to work within mechanical systems without creating noise and vibration.

 

Longer Service Life

The efficiency and reliability of tapered roller bearings make them apt for high-performing applications and offer them longer service life without the scope of functional damage or wear and tear

Storage of Tapered Roller Bearing

If roller bearings need to be stored for a period of time before use, proper storage conditions should be maintained.
They should be stored in a clean, dry, and cool environment.
Avoid storing them in areas with high humidity or extreme temperatures.
The bearings should be kept in their original packaging or in a protective covering to prevent exposure to contaminants.
Additionally, bearings should be stored in a way that avoids any static loads or deformations. For example, they can be placed on racks or supports in a horizontal position.

FAQ

 

Q: What features does a tapered roller bearing have?

A: Tapered roller bearings are separable into a cone assembly and a cup. The non-separable cone assembly consists of the inner ring, the rollers, and a cage that retains and evenly spaces the rollers. The cup is simply the outer ring.

Q: Do tapered roller bearings need preload?

A: Preloading your bearings is important, especially if you are using a wheel with a tapered bearing. The majority of applications will either use a tapered bearing, roller bearing, or ball bearing.

Q: When to replace tapered roller bearings?

A: There is a break in any of the ferrules and rolling elements.
There are obvious jams on the rolling surface, ribs and rolling elements.
The cage is significantly worn or the rivets are significantly loose.

Q: Why does a tapered roller bearing have true rolling motion?

A: That's because rollers and races are precisely tapered so that all lines coincident with their tapered surfaces always meet at a common point on the axis of the bearing. This means friction-free operation, minimum wear, greater precision.

Q: How to check tapered roller bearings?

A: Separable bearings such as tapered roller bearings may be checked by individually examining their rolling elements and the outer ring raceway. Large bearings cannot be rotated manually; however, the rolling elements, raceway surfaces, cages, and contact surface of the ribs should be carefully examined visually.
