1. The basis for distinguishing between high-speed bearings and low-speed bearings:

Because of the different ways of use, bearings can be divided into high-speed bearings and low-speed bearings, but although this is said, their distinction is not simply based on how many revolutions can be turned to count, and some low-speed bearings per minute The rotation speed can reach nearly tens of thousands of revolutions, but some are called high-speed bearings, and their rotation speed is only a few hundred revolutions per minute. Their distinction is based on the linear speed of the bearing. The high-speed bearings are high-speed bearings. The low-speed bearings are low-speed bearings.

2. Different types of high-speed bearings and low-speed bearings:

Low-speed bearings generally use rolling bearings, high-speed general sliding bearings, that is, the places responsible for rotation in the bearings are different, this type of low-speed bearings uses round, cylindrical, or even conical rotors ; And high-speed bearings use bearing bushes, please pay attention: Rongji igniter.

3. The difference between high-speed bearings and low-speed bearings can be seen in appearance:

From the appearance, you will find that the surface of the high-speed bearing will look smoother, there will be no roughness or some potholes on the surface like the low-speed bearing, the distance between the outer ring and the inner ring is very small, the bearing The accuracy is relatively high; at low speeds the surface is relatively rough and the accuracy is lower.

MKL BEARINGS can produce high speed bearing such as 608 ceramic bearing ,MR-126 ceramic bearings ,for more informations pls contact with us .
