H718-2RZC Double-sided Sealed Bearing

The H718-2RZC Double-sided Sealed Bearing is equipped with tightly fitting sealing devices on both sides, which are like a solid defense line. They can keep out impurities such as dust, water vapor, and oil stains, and at the same time firmly lock in the internal lubricating grease, ensuring that the inside of the bearing is always in a clean and well-lubricated state.

Performance Advantages

Superb Environmental Adaptability: Thanks to its excellent double-sided sealing, the bearing can operate normally in harsh environments such as dusty factory workshops, wet outdoor equipment, and machinery with oil fumes. This greatly reduces the probability of failures.
Long-lasting Durability: The combination of high-quality materials and precision manufacturing processes endows the bearing with excellent fatigue resistance and outstanding wear resistance. It reduces the downtime caused by frequent replacements and lowers the maintenance costs of the equipment.
High-precision Operation Assurance: The precise cooperation between various components makes the radial runout and axial play of the bearing almost negligible during rotation, perfectly meeting the strict requirements of precision instruments and high-end equipment for high-precision rotation.
Low Friction and High Efficiency: The optimized design of the rolling elements and the cage effectively reduces internal friction, generating less heat during operation. This not only saves energy and reduces consumption but also prevents performance degradation caused by overheating, ensuring the efficient operation of the equipment.

Application

The bearings can be used in the following industries

Industrial Automation Production Lines: For example, in the joints of robotic arms and the roller bearings of conveying devices, it ensures the precise and stable operation of the equipment in complex and harsh industrial environments.
Automobile Manufacturing and Maintenance: It is used in key parts of automobiles such as engines, transmissions, and wheel hubs, coping with complex road conditions and variable working conditions, and helping automobiles to drive safely and reliably.
Agricultural Machinery and Equipment: In agricultural machinery such as tractors and harvesters, it adapts to the dusty, wet, and highly vibrating working conditions in the fields, ensuring the long-term stable operation of the equipment and improving agricultural production efficiency.
Precision Instruments and Meters: For the rotating shafts of optical microscopes and electronic measuring instruments, relying on its characteristics of high precision and low friction, it enables precise measurement and observation, promoting the smooth progress of scientific research, quality inspection, and other work.
