Product Description

Komel's high quality Full Complement Cylindrical Roller Bearings have no support structure but are filled with cylindrical bearings between the inner and outer rings. This design increases the number of rollers in the bearing, thus increasing the contact area between the bearing and the raceway. There is no support frame to fill the space, the wheels are arranged closer to each other, and the radial weight on the carrier is smaller. This can provide greater weight-carrying capacity in a smaller space. These bearings have the characteristics of high weight, high strength, compact structure, and low rotational speed. Our company's full-service cylindrical wheelchairs are widely used in heavy machinery, lifting and transport equipment, industrial vehicles and fast-moving heavy machinery.

Suffixes

Related to internal design

· E: Enhanced design. This design usually means an increase in the number of rolling elements, optimization of their sizes, or improvement in the cage structure, thereby enhancing the bearing's load - carrying capacity. For example, some single - row cylindrical roller bearings of SKF with the suffix "E" feature an optimized internal geometry and cage design, resulting in higher rated loads.

· EM: Enhanced design with a machined brass cage. Compared with ordinary cages, the machined brass cage has better strength and wear resistance, making it suitable for more demanding working conditions.

· MA: It uses a machined brass cage guided by the outer ring. This type of cage can provide good lubrication and heat dissipation performance. Meanwhile, the outer - ring guidance ensures the stability of the cage during high - speed rotation.

Related to tolerance class

· P0: Normal tolerance class. This is the most common tolerance class, suitable for most general industrial applications.

· P6: A tolerance class stricter than P0. It is applicable to situations where a certain level of rotational accuracy is required, such as the feed axes of machine tools.

· P5: Higher precision than P6. It is commonly used in the main shafts of high - precision machine tools, aerospace equipment, and other fields with extremely high precision requirements.

Related to clearance

· C1: Smaller than the normal clearance. It is suitable for situations where strict control of axial and radial displacements is required, such as the main shafts of precision machine tools.

· C2: The clearance is smaller than the normal clearance but larger than C1. It is used when a certain level of clearance control is needed but not as strict.

· CN: Normal clearance. It is the most commonly used clearance class, suitable for most general industrial applications.

· C3: The clearance is larger than the normal clearance. It is often used in high - temperature environments or when the interference fit between the shaft and the bearing housing is relatively large, to compensate for the decrease in clearance caused by temperature changes or the fit.

· C4: The clearance is larger than C3. It is suitable for higher - temperature environments or larger interference fits.

· C5: The largest clearance. It is generally used in special working conditions with high temperature, high speed, or large interference fits.

Application

Machine tool industry: It is commonly used in the main shafts of machine tools. It can withstand the radial cutting forces during the machining process of machine tools, ensuring the rotational accuracy and stability of the main shaft, thus improving the machining accuracy and surface quality.

Motor industry: In electric motors, single-row cylindrical roller bearings are used to support the rotor, bearing the weight of the rotor and the radial forces generated during operation to ensure the normal operation of the motor.

Metallurgical equipment: For example, the working roll and backup roll bearings of rolling mills can withstand the huge radial loads during the rolling process, ensuring the stable operation of the rolls and the rolling accuracy.

Mining machinery: In equipment such as crushers and ball mills, single-row cylindrical roller bearings are used to support heavy-duty components, bearing the impacts and loads generated during the crushing and grinding of ores.
