Tapered roller bearings are rolling bearings that can withstand combined loads (radial + axial), and are mainly suitable for high load and high rigidity applications. The rolling element of the bearing is a tapered roller, the raceway is a conical surface, the inner and outer rings can be installed separately, and the clearance can be adjusted. It has extremely high load adaptability and flexibility. According to the number of rows, tapered roller bearings can be divided into single-row, double-row, four-row and other structures, which are suitable for various needs from medium-sized machinery to heavy equipment. They are key components of automobiles, machine tool spindles, reducers, rolling mills and other equipment.Tapered roller bearings are rolling bearings that can withstand both radial and axial loads. The rolling elements are tapered rollers, which are in linear contact with the inner and outer ring raceways, thereby increasing the load-bearing capacity. According to the structural form, tapered roller bearings can be divided into single-row, double-row and four-row. In industrial machinery, tapered roller bearings are widely used in rolling mills, reducers, heavy equipment and other fields due to their excellent load-bearing capacity and durability, and have become an indispensable key component in many mechanical systems.
Tapered roller bearings are composed of an inner ring (including rollers and cages) and an outer ring, and are separable structures. All raceways and roller cones converge at one point on the same axis to achieve ideal rolling line contact. This structure enables it to not only withstand large radial loads, but also effectively withstand unidirectional or bidirectional axial loads according to the size of the cone angle. Especially when installed in pairs, it has a strong axial force balancing ability and high overall rigidity, and is suitable for high-speed, heavy-load and impact load occasions.Tapered roller bearings are roller bearings that use tapered rollers as rolling elements. Their special design enables them to withstand radial and axial loads at the same time. Tapered roller bearings are usually composed of an inner ring, an outer ring, rollers and a cage. The raceways of the inner and outer rings are both tapered, and the rollers roll along the taper. This geometric design allows the rolling element to form a specific contact angle with the inner and outer rings (usually 15°-30°), which can withstand radial loads and unidirectional axial loads at the same time. The load-bearing efficiency is more than 3 times higher than that of ordinary roller bearings.
Strong combined load capacity:
suitable for bearing simultaneous radial load and axial load
Variable cone angle:
the larger the cone angle, the stronger the axial load capacity (such as 27°-30° for 313 series)
Separable structure:
the inner ring and outer ring can be installed separately, which is convenient for assembly, maintenance and preload
Adjustable clearance:
radial and axial clearance can be adjusted by spacers or installation methods to achieve precise control
High stability when used in pairs:
single rows need to be used in pairs to balance axial forces and improve system stability and life
Strong rigidity:
rollers and raceways are in line contact, load distribution is uniform, rigidity is high, and deformation is not easy
Suitable for high impact load occasions:
especially double-row and four-row structures, which can meet the needs of heavy-duty equipment such as rolling mills
Tapered roller bearings are widely used in many industries and mechanical equipment due to their high load-bearing capacity and ability to withstand both radial and axial loads. They are particularly suitable for heavy loads, impact loads, and precise axial positioning conditions.
(1) Automotive industry: Tapered roller bearings are used in automotive wheel hubs, gearboxes, differentials, and other parts. When driving, cars need to withstand combined loads such as radial impact and axial force. Tapered roller bearings can provide stable support to ensure the safety and durability of vehicle driving.
(2) Industrial machinery: Tapered roller bearings are widely used in machine tool spindles, reducers, gear transmission systems, and heavy mechanical equipment. Industrial equipment usually operates under high loads, high speeds, or complex load conditions. Tapered roller bearings can provide sufficient rigidity, reduce mechanical vibration, and improve processing accuracy and operating stability.
(3) Railways and rail transit: Tapered roller bearings are used in key components such as axle boxes and gearboxes of locomotives. Railway locomotives are subjected to huge loads and long-term impacts during operation. Therefore, the wear resistance and high load-bearing capacity of the bearings are crucial to the stability and service life of the trains.
(4) Mining, construction and wind power equipment: Tapered roller bearings also play an important role. For example, mining crushers, excavators, cranes and conveying equipment usually need to work under harsh conditions, and tapered roller bearings have good impact resistance and anti-pollution performance.
