Product Description

Single Row Taper Roller Bearings manufactured by KOMEL consist of an inner ring, a plain bearing and a housing. The road in the house was cleared, and cars drove on the road. The rod is used to define the distance and gap between the wheels, allowing for an even distribution of the inner spool. Typically, metal is used. If the outer diameter of the beam is too large, solid steel columns are used.

A raceway for the outer ring was also installed, in combination with the inner drive ring to provide support for the connected wheels. The outer and inner rings of the ring assembly can be separated, making assembly and disassembly easier.

Our company's high-quality Single Row Taper Roller Bearings are widely used in the automotive industry, machinery manufacturing, mining machinery and wind power generation, among others.

Suffixes

Related to Dimensions and Structures

· E: Reinforced design, which generally means that the dimensions of the bearing's rollers and raceways are increased to improve the bearing's load - carrying capacity. For example, in some heavy - load application scenarios, using reinforced tapered roller bearings can better withstand large radial and axial loads.

· J: The inner ring is equipped with oil holes and oil grooves for lubrication. This design facilitates the injection of lubricating oil into the bearing, ensuring good lubrication during high - speed or heavy - load operation and reducing wear and heat generation.

· JR: The outer ring is equipped with oil holes and oil grooves, also aiming to improve the bearing's lubrication conditions.

· N: The outer ring has a snap - groove for installing a snap - ring, which can achieve axial positioning of the bearing and prevent the bearing from moving axially on the shaft.

· NR: The outer ring has a snap - groove and comes with a snap - ring. Compared with bearings with only a snap - groove, this configuration is more user - friendly. The axial positioning can be completed directly after installing the snap - ring.

Related to Tolerance Classes

· P2: The highest level of dimensional accuracy and rotational accuracy, suitable for application scenarios with extremely high precision requirements, such as the spindles of precision machine tools.

· P4: A high - precision class, with accuracy second only to the P2 class. It is commonly used in some high - speed and high - precision mechanical equipment, such as aero - engines and high - speed grinding machines.

· P5: A common high - precision class, which can meet the requirements of most industrial equipment with certain precision requirements, such as CNC machine tools and textile machinery.

· P6: The accuracy is lower than the P5 class but higher than the normal class (the normal class is indicated without a suffix). It can be used in machinery with general precision requirements, such as agricultural machinery and general machine tools.

Related to Internal Clearance

· C1: The clearance is smaller than the normal clearance, suitable for occasions requiring high precision and low vibration, such as precision instruments and optical equipment.

· C2: The clearance is smaller than the normal clearance but larger than that of the C1 class. It is commonly used in some precision machinery with certain requirements for clearance.

· C0: Normal clearance, which is the most commonly used clearance class and is suitable for most mechanical equipment under general working conditions.

· C3: The clearance is larger than the normal clearance, commonly used in working conditions such as high temperature, high speed, and heavy load. In these cases, the bearing's clearance will decrease due to factors such as thermal expansion. A larger initial clearance can ensure that the bearing still has a proper clearance during operation.

· C4: The clearance is larger than that of the C3 class, suitable for special working conditions with higher temperature, higher speed, and heavier load.

Related to Cages

· M: Solid copper alloy cage, which has good strength, wear resistance, and lubrication performance. It is suitable for high - speed, heavy - load, and high - temperature working environments.

· T: Synthetic resin cage, which is lightweight, has low noise, and good self - lubrication performance. It is commonly used in high - speed and low - noise application scenarios, such as power tools and household appliances.

· TN: Glass - fiber - reinforced nylon 66 cage, which has good strength and toughness and also has certain self - lubrication performance. It is widely used in many common industrial applications.

Related to Materials and Heat Treatment

· W: Special materials, usually indicating that the bearing is made of special steel or other materials to meet specific working conditions, such as corrosion resistance and high - temperature resistance.

· G: Subjected to special heat treatment, which improves the bearing's hardness, wear resistance, and anti - fatigue performance. It is suitable for applications under harsh working conditions and heavy loads.

Application

Automotive Industry

Single-row tapered roller bearings are commonly used in the front and rear wheel hubs, differentials, transmissions and other parts of automobiles. In these applications, they can withstand the radial and axial loads generated during vehicle operation, ensuring the stable rotation of the wheels and the normal operation of the transmission system.

Machinery Manufacturing

They are widely used in the spindles, feed shafts and other parts of various machine tools. They can bear loads such as cutting forces, guaranteeing the machining accuracy and stability of the machine tools. In addition, in other machinery manufacturing fields such as textile machinery, printing machinery and packaging machinery, they are also commonly used to support rotating components, transmit power and bear loads.

Mining Machinery

In equipment such as crushers, ball mills and conveyors, single-row tapered roller bearings can withstand huge impact loads and vibrations, ensuring the reliable operation of the equipment in harsh working environments.

Wind Power Generation

Single-row tapered roller bearings are used in the main shafts, yaw systems and pitch systems of wind turbines. They can bear loads such as the gravity, axial forces and torques of the wind wheels, meeting the requirements for high reliability and long service life of wind power equipment.
