When EDA bearings, inner ring and outer ring raceway surface of spherical roller bearings due to contact with the rolling scrolling, and running track to the dark side, the running track of the raceway surface does not belong to abnormal, this variable can tell the load conditions, so when disassembling bearing, please pay strict attention and observation. The running track.
If you look closely at the track, it will learn that only bear radial load, axial load, bearing the load torque, or extreme rigidity is not equal in the bearing box. You can check whether the self-aligning roller bearing with the load and the installation error accident is big enough, and be held bearing loss for clues to the cause of.
The sealing contact seal is the sealing parts and the relative movement of the parts without gaps. This seal as the seal and a direct contact with, and therefore generally applies only to the low speed working condition, in. In the work of the big friction, heat is also high, so that the contact surface wear easily, leading to the sealing effect and performance degradation. Contact seals used a felt sealing, leather cup sealing structure.

According to the requirements of EDA bearing working conditions and the working environment of the sealing degree in the design of spherical roller bearing is often seal the form of comprehensive use of various, in order to achieve a better seal effect.
1 bearing assembly method because the bearings are precision products, such as assembling improper channels, it is easy to damage Koyo bearings, bearing damage. There should be a special mould in the bearing assembly, not axis pressure can only be a small circle, circle, only the stress cycle. General requirements of pneumatic or hydraulic, pressure for use on the lower mould, installed in a horizontal state, if you prefer bearing channels will cause damage to a power, and make the bearing noise.
2 bearing when removing and installing the same careful. Careful not to damage the Koyo bearings and other parts, especially the interference fit bearing disassembly, difficult operation. Therefore, in the design stage to think ahead to the ease of disassembly, removal tool based on design is also very important. In the demolition, according to the order of disassembly method, drawing, with the condition of spherical roller bearings survey, to obtain the disassembly operation no danger of anything going wrong.
Allow 3 EDA bearing material foreign hard particles clamping and lubricants to prevent scratching or (and) ability to abrasive wear. On metallic materials, low hardness and elastic modulus of low, clamping is good, is not necessarily non-metallic materials, such as carbon graphite, lower elastic modulus, but clamping is not good. Spherical roller bearing friction pieces generally relatively soft material and hard material, usually with a soft material bearing.
4 check the vibration of the bearing in the work from the peeling, indentation, rust, crack, wear will be reflected in the EDA bearing vibration measurement, bearing vibration on the spherical roller bearing damage is very sensitive, therefore, through the use of special bearing vibration measuring device (frequency analyzer etc) can measure the size of the vibration, through frequency cannot be inferred from abnormal situation.
