1045 linear guide pillar column bar rod tie rod bar bearing for hydraulic cylinders

1.Brief Introduction To 1045 Linear Guide Bar

Guide rods are slender structural units used to provide free motion in one direction. Commonly, the product surface is processed by hard chromium plating technology, and then it is mirror polished, with characteristics of friction resistance and corrosion resistance. 

Tie rods are often used in steel structures, such as bridges, industrial buildings, tanks, towers, and cranes. In automobiles, the tie rods are part of the steering mechanism. They differ from the archetypal tie rod by both pushing and pulling (operating in both tension and compression). In ships, tie rods are bolts which keep the whole engine structure under compression. They provide for fatigue strength. They also provide for proper running gear alignment which prevents fretting. They help to reduce the bending stress being transmitted to the transverse girder.

3.Heat treatment methods of 1045 guide bar

Induction hardening: it is a form of heat treatment in which a metal part is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly without affecting the properties of the part as a whole. The hardening depth is 1.5-5mm; medium/low-frequency quenching may lead to excessive depth and negative effect on strength; high-frequency quenching generally result in a shallow depth, and may ensure the balance of hardness and strength.

Quenching and high-temperature tempering: Generally, the heat treatment method combined of quenching and high-temperature tempering is called thermal refining, which is widely applied to various important structural parts, especially the connecting rods, bolts, gears and shafts working under alternating load. The tempered sorbite has better mechanical property than normalized sorbite of the same hardness. Its hardness depends on tempering temperature and relates to stability of tempering and sectional dimension of workpiece, and is generally HB200-350.

Induction hardened with Q&T: After induction hardening with Q&T, the piston rods could not only obtain greater mechanical properties, but also achieve a greater resistance to damage from external impact.

5.Characteristics of 1045 guide post

[Easy mounting]

With cross roller guide installed between the high-precision machined worktable and base, this product can be easily bolted to obtain a high-accuracy linear guide mechanism.

[High allowable load]

Rollers of high rated load are assembled in short pitch to form a high-loading capacity and high-rigidity linear guide mechanism with long service life.

[Various methods of use]

As rollers are arranged perpendicularly to each other, the system is able to evenly bear loads of 4 directions applied to the worktable.

[High corrosion resistance]

VRT-M and VRT-AM bases and worktable are made of stainless steel. In addition, the track, roller and roller holder and screws are also made of stainless steel. Therefore, it is high resistant to corrosion. It should be noted that VRU-M base and worktable are made of aluminum.
