How to install NSK thrust roller bearing NSK? What's the right way?
2. Inspection of shafts and housingsClean bearings and housings to ensure no scratches or burrs machined. No sanding, dosage forms, sand, chips, etc must be allowed in the case. Secondly, the size, shape and processing quality of the shaft and casing are checked to see if the drawing conforms to the drawing.The method of installing NSK bearings depends on the bearings, conditions and structures. Generally, the inner ring needs interference fit because of the rotation of the shaft. Cylindrical bore bearings, press by multiple presses, or by hot charging.
1, NSK bearing preparationBecause of the bearing after antirust processing and packaging, so don't come not to open the packing before installation. In addition, the antirust oil coated on the bearing has good lubrication performance. For general purpose bearings or filling grease bearings, they do not have to be cleaned and used directly. But for instrument bearings or for high speed rotating bearings, the use of clean oil to rust proof oil wash away, when the bearings are easy to rust, can not be placed for a long time.
Tapered bore, directly installed in the taper shaft, or sleeve installation.When the shell is installed, the general clearance is more coordinated, and the outer ring has an interference amount, which is usually pressed by a press, or a cold contraction matching method is installed after the cooling. With dry ice as coolant and cold contraction fit the installation, moisture in the air condenses on the surface of the bearing. Therefore, appropriate rust prevention measures are needed.Installation of NSK bearings is correct, affecting the life, accuracy, performance. Therefore, the design and assembly department for the installation of bearings should be fully studied. Hope to install according to operation standard.
