Description
What is the difference between ball bearing, sleeve bearing, and hydraulic bearing?
|
|
|
|
|---|---|---|
Dual BaII Bearingln the form of rolling friction, two ball bearings are used. Several microwave steel beads in the bearing rotate around the shaft core, so the friction is small and there is no leakage. The advantage of the double ball is that it has a long life and is suitable for fans with high rotation speeds. |
SIeeve BearingUse sliding friction sleeve bearings, and lubricants and drag reducers are used in sleeves. The advantage is Iow noise but the lubricant will volatilize due to the oil seal for a long time. You need to open the seal and add lubricant, otherwise, it is easy to wear and causes abnormal noise. |
Hydraulic BearingHydrauIic bearings are an upgraded version of sleeve bearings, which improves the non-sealed design of the bottom of traditional bearings, seals the bottom of the bearings, forming a closed oiI preservation design, adopts special Iow wear, high temperature grease resistance and runs more stable. |
