Product Description

Linear bearings are a linear motion system for the combination
of linear travel and cylindrical shafts. Because the bearing balls are
in contact with the outer point of the bearing, the steel ball rolls with
the minimum frictional resistance, so the friction of the linear bearing
is small and stable, and does not change with the bearing speed, so
the linear motion can obtain high sensitivity and high precision. The
consumption of linear bearings also has its limitations. The most
important is that the impact load capacity of the bearings is poor
and the bearing capacity is poor. Secondly, the linear bearings
have large vibration and noise at high speeds.

Linear bearings are made of cages in which the balls are
guided together with raceway segments and seals or shields.
Linear bearings are capable of carrying heavy loads and can be
used with closed or adjustable housings. We manufacture high
quality linear bearings in chrome steel or stainless steel with
hardened outer sleeves. There are also adjustable diameter
series chrome steel linear ball bearings with hardened jackets.
Our factory produces open linear ball bearings, with jacket
hardened balls and hardened steel ball cages. All FOCUS products
are of the highest quality and are designed to fully meet your
precision parts needs. Our technicians and engineers will also
work on customizing linear bearings to meet your individual needs.

Features :

Carbon steel bearings are characterized by low price, the use of bearing requirements are not too high. Hardness, wear resistance, life and so on are worse than conventional bearing steel bearings.

Carbon steel bearing performance description:

First, carbon steel bearings in terms of service life. Their service life is very different, the service life of bearing steel is long, many garbage bearings are carbon steel bearings, mainly hardness and wear resistance are not as good as bearing steel bearings.

Second, in wear resistance. Low carbon steel only in the surface carburizing surface quenching, and not all quenched. Many low-grade carbon steel bearings on the market are not hardened at all, and their wear resistance is very poor.

Third, in the process and use effect. Bearing use effect is related to the use of the environment, not to say that carbon steel bearings are not good, it depends on which machinery to use, because some do not need high-grade, with carbon steel bearings is appropriate. Of course, Luo Steel is better but the cost is much higher. The standard bearing steel is Gcr15.

Fourth, in bearing materials and performance. For example, the bearing ring and the rolling body should repeatedly withstand high contact pressure, and carry out rolling contact with sliding, while maintaining high precision rotation. Therefore, whether the material and performance of bearing ring, rolling body and cage meet the following requirements: high elastic limit; High rolling fatigue strength; To have a high hardness; Good wear resistance; Good toughness against impact load; Good dimensional stability. In addition, but also good processing. It has been proved that bearing steel has the properties required above, but carbon steel bearings cannot be guaranteed.

Fifth, it is not that the advantages of carbon steel bearings are not good enough for bearing steel to be available, it depends on where to use. Carbon steel bearing noise, life is very short, the pressure is very small, but can be used in hardness, limit speed is relatively small.

Surface strengthening technology can be classified into 5 categories: surface deformation strengthening, surface heat treatment strengthening, chemical heat treatment strengthening, surface metallurgy strengthening and surface film strengthening according to the physical and chemical process of surface strengthening technology.
