1: What is the difference between bearing steel chrome-plated rod and 45# steel?
The most commonly used bearing steel is GCr15. Comparison between
GCr15 and 45# steel: GCr15 is alloy steel, wear-resistant, while
45# is only medium carbon steel, which is generally used to make
more mold bases. Compared with bearing steel, No. 45 steel has poor
wear resistance. Bearing steel has high and uniform hardness and
wear resistance, as well as a high elastic limit.
2: Standards for the diameter of chrome-plated rods
Chrome-plated rods with a diameter of 12 mm, 45 steel after
quenching and before tempering, are qualified if the hardness is
greater than HRC55 (up to HRC62). The actual application hardness
is HRC55 (high frequency quenching HRC58). 2. Do not use the heat
treatment process of carburizing and quenching for 45 steel. After
quenching and tempering, the parts have good comprehensive
mechanical properties and are widely used in various important
structural parts, especially those connecting rods, bolts, gears
and shafts that work under alternating loads. But the surface
hardness is low, not wear-resistant. Tempering + surface quenching
can be used to improve the surface hardness of parts. 12 mm
diameter chrome-plated rod, high-frequency chrome-plated rod is
made of 45# steel with chrome-plated surface, widely used in
mechanical equipment, etc., ordinary optical axis (piston rod)
hardness is about 20 degrees, high-frequency hardened optical axis
(quenching/tempering) Optical axis) has a hardness of about 55
degrees. It can be used in conjunction with linear bearings, shaft
bearings or aluminum brackets. The wear resistance and corrosion
resistance of the product promote the high precision, high speed,
high competitiveness, durability, and large The performance of the
equipment is greatly improved; at the same time, it has a
considerable price advantage. The 12 mm diameter chrome-plated rod
and the high-frequency precision linear optical axis are a new type
of standard parts that are gradually adopted by advanced machinery
industries around the world in recent years. It is widely used in
electronics, packaging, textiles, printing, engineering,
transportation, steel, mining, hydraulic cylinders, cylinders,
operating rods, adjusting rods, linear motion. The conventional
specifications of chrome-plated rods are mainly Φ3, Φ4, Φ6, Φ8,
Φ10, Φ12, Φ13, Φ14, Φ15, Φ16, Φ17, Φ18, Φ20, Φ22, Φ25, Φ28, Φ30,
Φ32, Φ35, Φ38, Φ40, Φ45, Φ50, Φ55, Φ60, Φ63, Φ65, Φ70, Φ75, Φ80,
Φ85, Φ90, Φ100, Φ120 and other high frequency. Chrome-plated rods
are divided into two series, namely LM and LME series. Its
code-named LM series is used in Asia, Southeast Asian countries,
Japan, Korea, China, etc. Taking the metric size as the standard,
the outer diameter tolerance of the used linear shaft is generally
h7. LME series are mostly used in Europe, the United States,
Germany, Italy and other regions. The inch size is used as the
standard, and there are also metric sizes. The outer diameter
tolerance of the used linear shaft is generally g6. The structural
characteristics of the two series are roughly the same except for
the different dimensions and aperture tolerances.
