Description
Tapered roller bearings are a type of rolling bearing used primarily in automobiles, trucks, industrial machinery and other equipment that require high load capacity. Compared to deep groove ball bearings, tapered roller bearings are designed to withstand greater axial and radial loads, making them particularly suitable for hubs, axles and high-load applications. Their structure consists of inner and outer rings, tapered rollers and cages, providing higher precision and longer service life.
Specification
| Material | High carbon steel, stainless steel, alloy steel, etc. |
| Size | The inner diameter, outer diameter, width, etc. can be customized according to different application needs. Common specifications include 35mm, 75mm, 120mm, etc. |
| Sealing | Sealed or open type is available. The sealed type has stronger dust and water resistance and can adapt to more complex environments. |
Production
Process
Material selection
High-strength steel or alloy steel is selected as raw material to ensure the wear resistance, load-bearing capacity and corrosion resistance of the bearing.
Raw material processing
The inner and outer rings and rollers are produced through forging, rolling and other processes. The rollers are tapered and the contact angle with the inner and outer rings ensures that they can withstand large loads.
Heat Treatment
High-temperature heat treatment is performed to enhance the hardness and wear resistance of the steel, ensuring long-term stable operation of the bearing under high load and high temperature environment.
Precision Machining
The inner and outer rings and rollers are precision machined, including turning, grinding, polishing, etc., to ensure the dimensional accuracy and surface quality of the products.
Assembly
The inner and outer rings, rollers and cages are assembled precisely to ensure the clearance between the rollers, lubrication effect and overall matching accuracy.
Sealing
Install sealing rings on sealed tapered roller bearings to prevent dust, moisture and other pollutants from entering and extend their service life.
Quality Inspection
Strict quality inspections are carried out, including noise testing, load capacity testing, accuracy testing, fatigue life testing, etc., to ensure that product performance meets high standards.
Packaging and Shipping
After passing the inspection, the tapered roller bearings will be cleaned, lubricated, packaged and ready for shipment.
Single row tapered roller bearings
The most common type, suitable for situations where radial loads and unidirectional axial loads are applied.
Double row tapered roller bearings
It has strong load-bearing capacity and is suitable for equipment that bears large loads. It can bear radial loads and bidirectional axial loads at the same time.
Sealed tapered roller bearings
Suitable for dustproof and waterproof working environment, increasing the durability and reliability of the bearing.
type
Application
Scenario
Used for sealing of automobile drive shafts, wheels, differentials and other parts to prevent oil leakage and protect internal systems
Such as the sealing of gear boxes, hydraulic pumps, compressors and other equipment to ensure that lubricating oil does not leak
Such as drive shaft seals for excavators, bulldozers and other equipment to protect transmission systems and bearings
Used for ship gearbox and transmission shaft seals to retain oil and prevent external pollutants from entering
Sealing systems for equipment such as tractors and harvesters
Such as the sealing of mining vehicles and mining equipment to ensure the normal operation of the equipment
Features
The contact angle design between the tapered roller and the inner and outer rings enables the bearing to bear large radial loads and axial loads at the same time, making it suitable for heavy load applications.
Due to the precise structural design, it can provide stable operating performance in high load and high temperature environment.
Through heat treatment and precision machining, the hardness and wear resistance of the bearing are improved, and the service life is extended.
Suitable for a variety of harsh working environments, including high temperature, high speed, high load and harsh climate conditions.
Good sealing design effectively prevents contaminants from entering, reduces maintenance frequency, and ensures long-term reliable operation
