　　General, the axis is called the bearing based on the fixed end of nsk bearing side radial and axial support of the two bearings, the burden of the second radial and axial loads, from a fixed position relative to the box axis and the role Thrust Bearing of axial displacement. On the other side is called the free end, only the burden of radial load and axial relative movement can be.

　　Fixed end of the needle bearings and shaft must be, and with a fixed bearing housing, is more appropriate to withstand complex ball bearing radial load pin, for example, deep groove ball bearings, spherical roller bearings and double row or pair angular contact ball bearings or tapered roller bearings needle. Radial nsk bearing the burden of a simple combination, such as inside and outside the ring, cylindrical roller bearings without Special Bearing ribs and a deep groove ball bearing or the four-point contact ball bearing or a combination of two-way thrust bearing radial load, and can be used as a fixed side bearing. At this point, the second two-way bearings must be installed to provide axial location, but with the Pressed Bearing housing to maintain some of the radial interval. The free end of the bearing in the shaft due to thermal diffusion, the length change, within the needle bearings in the extrusion does not occur. Axial displacement within the bearing, the bearing may occur with the support ring may also occur.

　　"Cross fixed" mentioned the bearing arrangement, nsk bearing one-way placement in the shaft and the opposite direction. The main short portfolio. All at least able to withstand the radial direction of an axial bearing load is applied, including deep groove and angular contact ball bearings, tapered roller bearings and cylindrical roller Needle Roller Bearing NJ type, angular contact ball bearings use conical needles roller bearings, or, when the need to impose some cases, pre-press.
