THK bearings

THK bearings
A. Guide Ball Bushing / Linear Bearing Structure and Features:
1.LG type with 4 arc-shaped deep channel (rolling channel), do not need to prevent the bearing sleeve rotation mechanism. Compared with the linear bearing LM type of the same size products, its rated load increased significantly. Replacing the linear bearing with the guide ball guide allows compact, low-cost and long-life guide structure.
1). Compared with the linear bearing load rating UP: LG ball contact structure with circular arc R groove deep groove contact, and the contact with the same size linear bearings compared to its rated load increased more than 2 times.
2) There is no need to prevent the rotation of the rolling channel: LG-type deep groove with circular arc, no longer need linear bearings LM-type anti-rotation mechanism, can make the device more compact.
3) Dimensional interchange with linear bearings LM type: LG type and linear bearings The LM type bearings have the same diameter and length, so the LM type can be replaced with the LG type.
4). Nuts and Shafts Non-package products (freely combined): The LG version is the same as the linear bearings with the freedom to combine the LG nut with the LG shaft.
2. Linear bearing LM type and cylindrical LM optical axis with the use of, to be able to complete the infinite linear motion of the linear motion system. The point-to-point contact between the load-bearing steel ball and the LM optical axis allows for less load but allows for high-precision and light linear motion with frictional resistance.
Bearing sleeve made of high-carbon chromium bearing steel, after heat treatment on its internal and external surface grinding.
Linear bearings are used in a wide range of applications, including precision instruments for office equipment and their peripherals, various gauges, automatic recording devices and digital three-dimensional gauges, as well as multi-axis drilling machines, punching machines and tool grinding machines, Printing machinery, card machines and food packaging machines and other industrial machinery sliding parts.
1). Interchangeability: As the linear bearings of various parts of the size tolerance is standard, so interchangeable. The LM optical axis utilizes a cylindrical grinder to make it easy to grind and to achieve high-precision mating clearances.
2) High-precision retainer: Guide the ball retainer 3 to 8 columns for the overall casting structure, it can be in the direction of movement of the ball correctly guide the ball, and can achieve stable walking accuracy.
Small diameter products use a cast-in-one synthetic resin retainer to reduce noise during operation and provide excellent lubrication.
3) Rich Type: THK offers a wide variety of types such as standard type, adjustable gap type, open type, long type, flanged flange type, and flange type LM ball bushings. Users can select the appropriate type .
B. Needle Cam Guide Features:
Needle roller cam guide is a compact, high rigidity with shaft bearings. Its interior with needle roller bearings, cam mechanism or linear motion can be used as a guide roller. Due to its outer ring in direct contact with the mating surface at the same time for rotational movement, this product is thick-walled structure, designed to withstand the impact load. In addition, the inside of the outer ring, equipped with precision retainer needle roller, which can prevent the product side down, to achieve excellent rotation performance, and can withstand high-speed rotation. The shape of the outer surface of the outer ring is divided into spherical and cylindrical. Spherical outer ring easy to absorb the deformation of the shaft center, helps to reduce the bias load. Needle roller cam guides are used in a wide range of applications such as cam machines for automatic machines, special machine tools and carrying systems, conveyors, bookbinding machines, tool changers for machining centers, rotary tables, automatic sprayer and automatic warehouse sliding Forklift and so on.
C. Roller Guide Features:
Roller guide is a compact, highly rigid bearing system. Its internal needle roller bearings can be used as a cam plate and linear guide roller guide, because of its outer ring in direct contact with the mating surface for rotational movement, this product is thick-walled structure, designed to withstand the impact load. In addition, the inside of the outer ring, equipped with precision retainer needle roller, which can prevent the product side down, to achieve excellent rotation performance, and can withstand high-speed rotation.
Roller guide is divided into two types: separate type, the inner and outer rings can be separated; non-separate type, the inner and outer rings can not be separated. The shape of the outer surface of the outer ring is divided into spherical and cylindrical. Spherical outer ring easy to absorb the deformation of the shaft center, helps to reduce the bias load. Roller guides are used in a wide range of applications, such as automatic machines, special machine tools and cam systems for delivery systems, conveyors, bookbinding machines, tool changers for machining centers, rotary tables, auto sprayers and automated warehouse slide trucks Wait.
D. Spherical Plain Bearings Features:
Spherical plain bearings SB type, SA1 type is designed for heavy duty self-aligning sliding bearings. The inner and outer rings of these models use hardened and ground high-carbon chromium bearing steel and are then phosphate treated to be highly resistant to corrosion and wear prior to MoS 2 sintering . Spherical spherical plain bearings can withstand large radial loads and thrust loads in both directions. And because of its high impact load resistance, it is most suitable for low-speed heavy-load rocking parts such as cylinder rotation support parts or hinges of various construction machinery and civil engineering machinery, and truck suspension buffers.
E. Rod End Spherical Features:
The rod end spherical joint is constructed by using a ball bearing for precision ball bearings on a spherical surface portion and wrapping a steel ball by die casting to form a retainer and then connecting the shank portion by special welding. Through this original manufacturing method, the mirror surface of the steel ball is copied to the spherical surface of the retainer to make full contact with each other. As a result, a smooth movement of clearance is achieved.
1). Miniaturization design: The BL type is designed to maintain its full strength and its compact shape due to its highly balanced design. Therefore, this model is best for steam
A vehicle height sensor connection or a transmission control.
2). Sphericity: 0.001 mm: Since the sphericity of the steel ball for bearings is directly replicated to the spherical surface of the neck with the shank, it can be realized with a clearance (sphericity of 0.001 mm)
Smooth movement, so that the movement of the link mechanism can produce good maneuverability and feel.
F. Face ball bearings Features:
Faced ball bearings are self-aligning plain bearings with a spherical inner ring that has the same precision and hardness as bearing steel balls. By combining a spherical inner ring, whose sliding surface is mirror-finished, and a properly designed holder, the faceted ball bearings enable a very smooth and swiveling movement with no play.
