Miniaturized and lightweight, why you should choose thin section bearings?

thin section bearings
Thin-walled bearings have achieved extremely thin bearing cross-sections and have also achieved product miniaturization and lightweight. The diversity of products expands their use. It is generally divided into plastic seal-RS, iron seal-ZZ, plane, iron card-K, copper Card-m.
Product Features of thin section bearings
In order to obtain low friction torque, high rigidity, and good rotation accuracy of the bearing, a small outer diameter steel ball was used. The use of hollow shafts ensures space for lightweight and wiring. Thin-walled bearings have achieved extremely thin bearing cross-sections and have also achieved product miniaturization and lightweight. The diversity of products expands their use.
The thin-walled 6700 and 6800 series are available in a variety of dust caps, flanges, stainless steel, and wide formats.
Lubrication purpose of thin section bearings
The purpose of the lubrication of the rolling bearing is to reduce the internal friction and wear of the bearing, prevent sticking and its lubricating effect is as follows.
Reduce the friction and wear in the contact parts of the bearing rings, rolling elements, and retainers to prevent metal contact and reduce friction and wear.
The rolling fatigue life of the fatigue life is prolonged when the rolling contact surface is well lubricated during rotation. On the contrary, the viscosity of the oil is low, and the thickness of the lubricating oil film is not good, so it is shortened The frictional heat discharge, cooling cycle oiling method, etc. can be used to discharge the heat generated by the friction or the heat transferred from the outside and cool. Prevent the bearing from overheating and prevent the lubricating oil from aging. Others also have the effect of preventing foreign objects from entering the inside of the bearing or preventing rust and corrosion.

Sealing means
There are corresponding sealing devices installed on both ends of the bearing, but many people do not know what effect the sealing device has. Let’s take a look at the effect of the sealing device on thin-walled bearings.
1. The grease (oil) inside the bearing will not be lost during use, ensuring that the bearing is in a lubricating state;
2. Protect the external dust or harmful gas of the bearing from entering the bearing cavity to prevent damage to the bearing.
The sealing structure of the sealing ring is various, so the sealing effect is also different. The gap between the seal ring and the shaft is called non-contact seal. The smaller the gap is, the better the sealing effect is, but the smaller the rotation speed of the shaft is allowed, and vice versa. There is no gap between the seal ring and the shaft, which is called contact seal. The greater the contact area of the seal lip, the better the sealing effect, but the smaller the allowable shaft rotation speed, and vice versa. The main research content of the sealing technology is the research and development of the corresponding sealing device applied to different working conditions, as well as the commixture of the sealing ring material and the corresponding grease.
