FAQS

QWhat's the application of thrust ball bearing?

AIt is only applicable to the parts with one side axial load and low speed, and only to the parts with one side axial load and low speed, such as crane hook, instant water pump, instant centrifuge, Jack, such as crane hook, instant water pump, instant centrifuge, Jack, low speed reducer, etc. The bearing's shaft ring, seat ring and rolling body are separated, and the speed reducer, etc. The shaft ring, seat ring and rolling element of the bearing are separated and can be installed and disassembled separately.

QWhat's the feature of Single row Cylindrical roller bearing?

ALow friction (roller face / flange contact area) Open flange design, together with roller end design and surface finish, promotes the formation of lubricating oil film, resulting in lower friction and higher axial basic load rating. Long service life The logarithmic profile of the roller reduces the edge stress at the roller / raceway contact and the sensitivity to the deflection of the misaligned shaft. Improve operation reliability The surface finish of the contact surface between roller and raceway is beneficial to the formation of hydrodynamic lubricating oil film. Separable and interchangeable The separation components of SKF cylindrical roller bearings are interchangeable. This is convenient for installation, disassembly and maintenance inspection. High speed capability The cage is designed for high speed, high acceleration and impact load.

QWhat's the Bearing construction type of Single row Cylindrical roller bearing?

A1. The outer ring has no flange N0000 and the inner ring has no flange nu0000. The cylindrical roller bearing can accept large radial load, high limit speed, no binding of axial displacement of shaft or shell, and no axial load. 2. Nj0000 and nf0000 cylindrical roller bearings with both inner and outer rings with ribs can restrain the axial displacement of the shaft or the shell in one direction, and can accept small unidirectional axial load. Nu0000 + hj0000, nj0000 + hj0000 and nup0000 bearings can restrain the axial displacement of shaft or shell in the field of axial clearance of imported bearing, and can accept small bidirectional axial load.

QWhat's the method of adjusting the radial clearance of cylindrical roller bearing?

A1. The side clearance of the cylindrical and elliptical bearing shells can be adjusted by manual grinding and scraping or the method of repairing and scraping after the bearing split surface is padded and turned. 2. For the top clearance of cylindrical and elliptical bearing shells, the method of manual grinding and scraping or adding pad to the bearing split when the situation allows can be used for adjustment. 3. In principle, it is not allowed to repair and adjust the clearance of multi oil wedge fixed bearing bush. If the clearance is not appropriate, replace it with a new one. 4. For multi oil wedge tilting bearing pads, it is not allowed to repair and scrape the pads. If the clearance is not appropriate, replace the tiles. For tile with adjustable thickness, the amount of tile can be adjusted by adjusting the stainless steel pad on the back of the tile or reducing the thickness of the adjustment block. Pay attention to the thickness error of the tilting bearing bush with multiple oil wedges between the blocks of the same group shall be less than 0.01mm.
