2. Instructions for use:
-Installation: Before installing the NU321ECP bearing, ensure that the dimensions and accuracy of the bearing seat and bearing seat holes meet the requirements. Use appropriate tools and methods to correctly install the bearing into the bearing seat.
-Lubrication: Use appropriate lubricating grease or oil and lubricate according to operating conditions and requirements. Ensure that the bearings maintain good lubrication during operation.
-Maintenance: Regularly check the operation status of bearings, such as noise, vibration, and temperature. Regularly replace lubricants and clean bearings and related components.
-Temperature control: Ensure that the bearing operates within an appropriate temperature range to avoid the impact of excessive temperature on bearing performance. Take appropriate measures to control bearing temperature based on operating conditions and requirements, such as using cooling systems or insulation measures.
-Load: Select an appropriate load based on design requirements and bearing load capacity, and avoid exceeding the rated load capacity of the bearing. If there is impact load or uneven load, appropriate compensation measures or other types of bearings should be considered.
-Attention: Avoid excessive lateral force and vibration on the shaft. Follow the installation, maintenance, and operation guidelines provided by the manufacturer to ensure the correct use and long service life of the bearings.
Please note that the above are only general instructions for use, and the specific usage and installation steps may vary depending on specific applications and devices. It is recommended to refer to the relevant manuals and technical information provided by the manufacturer before using bearings.
