Bearing determines the quality of your bearings heater is good or bad, in order to extend the service life of skf bearing ad here outstanding smooth and normal operating environment, and give full play to the bearing operating functions. Rolling necessary with appropriate seal, in order to avoid the leak of slickener and dust, water vapor or other contaminants invasive.

1, a non-touch-seal
For non-touch sealing understanding is that the seals and their relative motion of parts do not touch, and the right gap sealing. A seal in this manner, in the job almost no conflict heat, no wear and is particularly applicable to high speed and high temperature applications. Used non-touch seal gap style labyrinth and gasketed not the same layout parting applied to is not the same occasion. A non-touch-seal the gap as small as possible is preferred.

2, touch seal
Touch sealing the seal is sealed to their relative movement of parts relative touch and no voids. Straight touch because seals and cooperation pieces, this seal touch, a greater conflict in the job, ...
... the heat, easy to form a smooth non-performing, the touch surface easy to wear, and resulting in sealing the role and function was reduced. Thus, it applies only in low-speed operating conditions. Common touch seal Felt seal, cup seal layout applied to different occasions. According to the bearing operating conditions and operating environment of the sealing degree in engineering often summarized the use of various sealing way to reach a very good seal.
Sealing and plus sealed ball bearings two categories. Bearing comes seal is produced bearing itself as having a sealing function devices. Such as bearings with dust cover, seals. This small sealed space, equipment apart convenience, cost is relatively low. Called bearing plus sealing function equipment, is produced in the device cap internal to the sealing apparatus having various functions. Sealed bearings plus selection should consider the following several major factors:

1), the bearing operating environment, the space occupied by big and small;
2) shaft bearing layout strengths, promised the viewpoint error;
3), the sealing of the peripheral speed of the outer;
4), the bearing operating temperature;
