Needle roller bearing RNAO5*10*8TN are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross-section, needle roller bearings have a high load-carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.
Needle roller bearing RNAO5*10*8TN has a high load-carrying capacity in addition to their low cross-section and stiffness. They are especially suitable for bearing arrangements where radial space is limited. Because needle roller bearing RNAO5*10*8TN only carries pure radial load and can not limit the axial displacement of the shaft relative to the housing. It is important to ensure that the inner ring axis and outer ring axis must be aligned during mounting the bearings.
Radial clearance adjustment method of cylindrical roller bearing:
Commonly used methods to adjust radial clearance of cylindrical roller bearing are as follows:
1. For the side clearance of cylindrical and oval bearing bush, it can be adjusted by manual grinding and scraping or repairing and scraping after turning and adding pad on the face of the bearing.
2. For the top clearance of cylindrical and elliptic bearing, manual grinding and scraping can be adopted, or when the situation permits, the bearing can be adjusted by adding mat on the face of the bearing.
3. For the multi-oil wedge fixed bearing bush, it is not allowed to repair and scrape and adjust the bearing bush gap in principle. If the gap is not suitable, the new bearing bush should be replaced.
4, for the multi-oil wedge tilting type bearing, not allowed to repair the scraping tile, the gap is not appropriate should be replaced due to the tile. For the tile with adjustable thickness, the amount of tile can be adjusted by adding a stainless steel pad under the adjustment block behind the tile, or by thinning the thickness of the adjustment block. Note that for the tilting type bearing bush with the multi-oil wedge, the thickness error between the same group of tiles should be less than 0.01mm.
