Split Taper Roller Bearing

The remarkable feature of the Split Taper Roller Bearing produced by KOMEL is that their bearing rings (inner ring and outer ring) can be axially split into two halves. This unique structure breaks the integral form of traditional tapered roller bearings and greatly facilitates the installation and disassembly process. During installation, unlike traditional bearings, there is no need to axially move the shaft or other complex components. Instead, only the two halves of the bearing need to be installed on the shaft and the bearing housing respectively, and then they are combined into a complete bearing through a specific connection method (such as bolt connection, etc.).

Tapered Rollers: Tapered rollers are used as the rolling elements. The tapered rollers have a line contact with the raceways of the inner and outer rings. This contact method enables the bearing to more effectively distribute the pressure when bearing the load, thus having a high load-bearing capacity. The number and size of the rollers are rationally designed according to the specifications of the bearing and the application requirements to meet the load requirements under different working conditions.

Cage: A cage is usually equipped, and its function is to evenly separate the tapered rollers and guide them to roll correctly on the raceways. The materials of the cage generally include stamped steel, machined brass, or engineering plastics, etc. Different materials are suitable for different working environments and working condition requirements. For example, the machined brass cage has good wear resistance and strength and is suitable for occasions with heavy loads and high-speed operation; the stamped steel cage has a lower cost and is suitable for general working conditions. When the split tapered roller bearing is in operation, it mainly bears radial loads and axial loads in a certain direction. When bearing the radial load, the tapered rollers roll on the raceways of the inner and outer rings, transmitting the radial force to the bearing housing; when bearing the axial load, the contact angle between the rollers and the raceways enables the axial force to be effectively borne and transmitted by the bearing. Due to its split structure, even in the case of a certain degree of misalignment or installation error in the shafting system, the bearing can adapt to this change through slight adjustments at the split surface, compensating for the impact of misalignment to a certain extent and ensuring the normal operation of the bearing.

Parameter (Specification)

Suffixes

MA: It indicates a machined brass cage guided by the outer ring. This kind of cage has good strength and wear resistance, and is suitable for some occasions with high requirements for bearing performance. The guiding method of the outer ring can make the cage more stable during operation, which helps to improve the rotational accuracy and service life of the bearing.

TVPA: It represents a window-type solid cage made of glass fiber reinforced polyamide, guided by the outer ring. The glass fiber reinforced polyamide material has the advantages of light weight, good self-lubrication, and corrosion resistance. It can maintain good performance under harsh working conditions such as high speed and high temperature. The structural design of the window-type solid cage can effectively guide the rolling elements, reduce the friction and collision between the rolling elements, and improve the operation efficiency of the bearing.

Application

Mining Machinery: Equipment such as crushers and ball mills generate strong impacts and vibrations during operation, and the loads are relatively large. Split tapered roller bearings can withstand the loads under such harsh working conditions, ensuring the stable operation of the equipment.

Metallurgical Equipment: In metallurgical equipment such as blast furnaces and rolling mills, bearings need to operate in environments with high temperatures, heavy loads, and a large amount of dust. Relying on their excellent performance, split tapered roller bearings can meet these demanding requirements, providing a reliable guarantee for the continuous production of metallurgical equipment.

Heavy-duty Vehicles: For the axle parts of large trucks, construction vehicles, and other heavy-duty vehicles, there are high requirements for the load-bearing capacity and reliability of the bearings. Split tapered roller bearings can effectively withstand various loads during the driving process of the vehicles, improving the operational safety and reliability of the vehicles.

Industrial Transmission Equipment: In some large industrial transmission devices, such as reducers and gearboxes, split tapered roller bearings are also widely used to support the shafting system and transmit power.
