Suffixes

Related to internal design

· The bearing suffix "VL2071" indicates that this bearing is an inner ring insulated bearing. The outer surfaces of both its inner and outer rings are provided with an aluminum oxide insulating coating, which belongs to the standard coating.

· The bearing suffix "VL0241" indicates that this bearing is an outer ring insulated bearing. The outer surface of its outer ring is coated with an aluminum oxide coating, which belongs to the standard coating, and the insulation capacity is as high as 1000V DC

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

· Motor field: In all kinds of motors, especially large - scale high - voltage motors, shaft current may be generated during motor operation. Electrically insulated cylindrical roller bearings can effectively protect the bearings from electrical corrosion damage, improving the reliability and service life of the motors.

· Variable - frequency drive equipment: With the wide application of variable - frequency technology, high - frequency harmonic currents are more likely to occur in motors and equipment driven by variable - frequency drives, exacerbating the shaft current problem. Electrically insulated cylindrical roller bearings are widely used in these devices to ensure their stable operation.

· Wind power generation: In the gearboxes and generators of wind turbines, electrically insulated cylindrical roller bearings can prevent damage to the bearings caused by currents generated due to reasons such as lightning strikes or electrical system imbalances, ensuring the normal operation of wind power generation equipment.
