First, the basic concept of stainless steel linear ball bearings:
Linear bearing is a linear motion system with high precision, low cost and low frictional resistance. The linear bearing is a direct acting system that uses the rolling motion of the ball to achieve infinite linear motion in combination with the guide shaft.
Since the carrier ball is in point contact with the shaft, the load used is small. The steel ball rotates with a very small frictional resistance, so that smooth motion with high precision can be obtained.
Second, the work process of stainless steel linear ball bearings
The stainless steel linear ball bearings is equipped with a steel ball cage inside the outer ring. The cage is equipped with a plurality of balls, and the balls are infinitely circulating. The two ends of the cage are fixed by a gasket retaining ring, and a notched window is arranged in the direction of the linear track in which the steel balls are subjected to the force work. This part is to make the loaded steel ball roll contact with the shaft with a very low friction coefficient. Relative movement.
Therefore, linear ball bearings are the most suitable bearings for mechanical equipment, automation equipment, energy-saving equipment, etc.
Third, classification of stainless steel linear ball bearings:
1, By material
Housing: stainless steel, bearing steel, aluminum alloy (straight bearing with seat);
Cage: resin, stainless steel, bearing steel;
Surface treatment: chrome plating, nickel plating, surface anodizing (linear bearing outer mount), etc.;
2, By shape
Open type, closed type;
Straight column type, single lining type (common type), double lining type (lengthened type);
Single-lined with flange, double-lined with flange;
Two-sided cutting flange type, intermediate cutting flange type, four-sided cutting flange type;
With fixed seat height square (fixed seat material aluminum alloy, surface anodized), with fixed seat wide square and so on.
3, By series
stainless steel linear ball bearings are divided into two series, namely LM and LME series.
The LM series is used in Asia, Southeast Asian countries, Japan, Korea, China, etc.
The LME series is mostly used in Europe, the United States, Germany, Italy and other regions. Two series of structural features, in addition to different sizes, different aperture tolerances, the structure is roughly the same.
