When using TIMKEN bearings must be valid between internal and external seals; to take into account the following factors, including environmental conditions, lubrication and sealing around speed, friction seal and seal friction caused by temperature rise. TIMKEN bearings, the last two factors are more important. Because a sealed heat of friction is very likely to produce TIMKEN bearings cannot accept. High-speed precision rolling bearings are often with non-rubber seal. Non-sealing characteristics of rubber seal formed by its cover structure, can be used for radial or axial, axial and radial combination. This sealing without friction and wear. Contact rubber seal to a sealed surface, due to the friction of contact will increase the temperature, rubber seals use is subject to certain restrictions. This form is rarely used for TIMKEN bearing seal; this form is suitable for low speed only.
Rubber seals used in conjunction with non-rubber seal, you can enhance the sealing effect. In practice, when the critical speed is less than 12 m/s,, can be v-shaped rubber seal, friction arising from this application is small, easy to install, using the economy.
