If you want to make the service life of the one-way Roller pin Bearing longer, then we must learn how to maintain the one-way Roller pin Bearing. What are the maintenance methods for one-way Roller pin Bearing?
1. Prevent the intrusion of pollutants and dust, reduce the relative movement of the rolling element and the raceway, and reduce wear.
2. Regularly add lubricating grease to ensure its good lubrication effect.
3. Oil and gas, oil mist or spray lubrication can be used to improve cooling conditions.
4. Further strengthening and improving the cleanliness of the lubricating oil can better extend the full load life of the one-way Roller pin Bearing.
5. Maintain the cleanliness of the full-load one-way Roller pin Bearing. The Bearing with high cleanliness has low vibration speed and low wear, which can increase the service life of the Bearing.
Since you want to maintain the one-way Roller pin Bearing, what are its lubrication methods?
1. One-way Roller pin Bearing grease lubrication
The one-way Roller pin Bearing uses grease as the lubricating medium. The advantage is that the grease has low fluidity, is not easy to leak, and the formed oil film has good strength, which is more conducive to the sealing use of the one-way Roller pin Bearing. At the same time, one-way Roller pin Bearing grease lubrication can also extend the maintenance time of lubrication, making Bearing maintenance easier. Lubrication of the unidirectional Roller pin Bearing with grease also has disadvantages. Compared with lubricating oil, the friction torque of lubricating grease is larger, so it is not suitable for one-way Roller pin Bearing that need high-speed operation. In addition, the cooling performance of grease lubrication is poor. If too much grease is added to the one-way Roller pin Bearing, the one-way Roller pin Bearing can overheat by stirring the lubricant.
2. One-way Roller pin Bearing oil lubrication
The one-way Roller pin Bearing adopts oil lubrication, which can achieve good cooling effect, especially for the one-way Roller pin Bearing with higher working temperature. The viscosity of lubricating oil used in one-way Roller pin Bearing is about 0.12~0.2 cm/s. If the load of one-way Roller pin Bearing is large and the working temperature is high, high viscosity lubricating oil should be selected, while the one-way Roller pin Bearing with faster speed is suitable for low viscosity lubricating oil. The disadvantage of one-way Roller pin Bearing oil lubrication is that oil lubrication requires the Bearing to maintain a good sealing state to avoid lubricating oil leakage. In addition, oil lubrication requires a complex oil supply device, which is not as convenient as grease in operation and use, which increases the maintenance workload of the one-way Roller pin Bearing.
