Tips: Precautions for spherical roller bearings

• The self-aligning roller bearing preload is carried out at room temperature, but in the working state, the driving shaft caused by the system micro-stretching temperature rise, the bearing preload will change, therefore, the preload setting should be considered to this factor.
• It needs the size of capacity, speed, and other conditions to set the reasonable use of spherical roller bearing preload to ensure the life of the transmission. If the pre-tightening force is too large, it will consume power and even cause overheating. If the preload is too small, under the action of body load, shaft rolling, and the gap between the outer rings, jumping, running, and transmission accuracy will increase to reduce noise, affecting the gear meshing, and seriously damaging the teeth and bearings.
• According to the assembly of different spherical roller bearings, such as: the bearing preload nut is directly rotated by axially compressing the inner ring of the inner bearing, and the inner and outer rings are rotated to eliminate the gap and achieve the purpose of bearing preload. To achieve common use: first, far beyond the pre-installed bearing, last of the nut, then back 1/4 turn. Assembly method, the advantage of this method is less investment, simple, practical, and it can be used under the premise of consistent good quality tapered roller bearings.
