Anonymous users2024-02-15Bearings with an outer diameter of 90mm and an inner diameter of 38mm are non-standard, and there is no standard model for non-standard bearings. Customized is required.
The calculation of the bore diameter of a standard bearing is as follows:
1.How to display an inner diameter of 10 mm or less.
For 62 9 slash bar behind the bearing inner diameter size 9mm
2.The inner diameter is between 10mm and 20mm (excluding 20mm), and the basic code is 00
Each represents an inner diameter of 10mm
12mm15mm
17mm such as.
The last two digits of 01 represent an inner diameter of 12mm
3.The inner diameter between 20mm and 490mm is multiplied by 5 for example in the last two digits of the bearing designation. The last two digits of 6020 are 20 times 5, and the inner diameter size is 100mm4The inner diameter is greater than 490mm
It is also represented by a slash.
The inner diameter size is 1000mm

Anonymous users2024-02-12The bearing model with an outer diameter of 80 mm and an inner diameter of 40 mm is 208, with an inner 40 outer 80 and a thickness of 18.
Support the rotating shaft and the parts on the shaft, and maintain the normal working position and rotation accuracy of the shaft, the rolling bearing is easy to use and maintain, reliable to work, good starting performance, and has a high bearing capacity at moderate speed. Compared with plain bearings, rolling bearings have larger radial dimensions, poor vibration damping ability, lower life at high speeds, and larger sound.

Anonymous users2024-02-11It is necessary to determine the width, inner diameter, outer diameter and CR and COR values of the bearing in order to determine exactly what type of bearing it is.
According to the following table, the bearing type with an inner diameter of 40 mm and an outer diameter of 90 mm can be spherical roller bearings, deep groove ball bearings, self-aligning ball bearings, cylindrical roller bearings, angular contact ball bearings, etc., and the domestic new and old models of different bearings are different, and the weight, speed, and performance will also be different.
The main function of the bearing is to support the mechanical rotating body, reduce the frictioncoefficient during its movement, and ensure its rotation accuracy.
