Product Description

Thin-walled bearings
The ultra-thin bearing section is realized, and the product is also reduced in size and weight. The variety of products expands its scope of use. It is generally divided into plastic seal-RS, iron seal-ZZ, flat surface, iron card-K, copper card-M.
Product Features
In order to obtain the bearing's low friction torque, high rigidity, and good rotation accuracy, steel balls with a small outer diameter are used. The use of hollow shafts ensures light weight and space for wiring. The thin-walled bearing realizes the extremely thin bearing section, and also realizes the miniaturization and light weight of the product.
The variety of products expands its scope of use.
The thin-walled 6700 and 6800 series have various types of dust-proof cover, flanged, stainless steel, and wide-format, etc., with a complete range. Classification Generally divided into plastic seal-RS, iron seal-ZZ, flat surface, iron card-K, copper card-M. For example: 608RS,6914ZZ,61926K,61844M. Quote Thin-walled crossed roller bearings CRA series thin-walled cross roller bearings (outer ring split type) are small, lightweight cross roller bearings made of thin outer ring and inner ring. Both are small and can withstand heavier loads. Therefore, the equipment is The mounting part of the bearing can be lightened.
The size of the inner and outer rings of CRB series thin-walled cross roller bearings (outer ring split type) is miniaturized to the utmost extent. Its structure is that the outer ring is divided into two parts, and the inner ring is an integral structure, which is most suitable for the inner ring. Where the rotation accuracy is high.. CRE series thin-walled crossed roller bearings (split inner ring) are structured in that the inner ring is divided into two parts, and the outer ring is an integral structure, which is most suitable for places where high rotation accuracy of the outer ring is required. Thin-walled ring bearings have high precision, are very quiet and have strong load-bearing capacity.
These ball bearings have three designs and are extremely small and mostly square in cross section. In these series, even with larger shaft diameters and bearing holes, the cross-section remains the same. These bearings are therefore called equal sections. It is this feature that makes the standard ISO series Thin-walled ring bearings are different from traditional bearings. Therefore, it is possible to choose a larger cross-section and use a bearing with a higher load-bearing capacity without having to change the shaft diameter. Thin-walled ring bearings can be designed to be extremely light and require little space. Deep groove ball bearings, four-point contact bearings, angular contact ball bearings Thin-walled ring bearings can be deep groove ball bearings (C), four-point contact bearings (X), angular contact ball bearings (E). The above various designs are provided in different series. The series depends on the size of the cross section. The ball matches the series. Deep groove ball bearings can support bidirectional axial load and radial load. Four-point contact bearings can support bidirectional Axial load and radial load; therefore they operate in the same way as double row angular contact ball bearings. Angular contact ball bearings can match the optimal number of balls and their contact angle is 30°. They support higher radial loads than deep groove ball bearings or four-point contact bearings, and can support axial loads from the same direction. For special needs, Angular contact ball bearings can also be provided as matching bearings.
Therefore, the rigidity and load-carrying capacity of these combinations are much higher than single-bearing products. The sealing device has corresponding sealing devices installed on both ends of the bearing, but many people do not know what the sealing device does? Let's take a look at what effect the sealing device has on thin-walled bearings.
1. Keep the grease (oil) inside the bearing from being lost during use and ensure that the bearing is in a lubricated state; 2. Protect the outside of the bearing from dust or harmful gases from entering the inner cavity of the bearing to prevent damage to the bearing. The sealing structure of the sealing ring is various, so the sealing effect is also different. If there is a gap between the sealing ring and the rotating shaft, it is called non-contact sealing. The smaller the gap, the better the sealing effect, but the lower the rotation speed of the shaft is allowed; the opposite is true. There is no gap between the seal ring and the rotating shaft, which is called contact seal. The larger the contact area of the seal ring contact lip, the better the sealing effect, but the lower the rotation speed of the shaft is allowed, and vice versa. The main research content of sealing technology is the research and development of corresponding sealing devices used in different working conditions, as well as the compatibility of the sealing ring material and the corresponding grease.
