Guide rollers with a circular groove - LFR Series

SG Series Gothic Groove Guide Pulley Embroidery Machine Bearing

The function of series SG rollers are same as the series LFR rollers. But they are mainly used in the flat track and in the condition required compact structure. After rollers are installed to the slider, the shaft will be not or seldom over the roller's side planes.

Features

• double row angular contact ball and thicker outer rings with gothic arch groove profile

• there are   two points contact ( 60 degree) between Gothic Arch Groove profile and shaft

• high quality carbon-chrome steel AISI 52100 steel or stainless steel AISI 440 C

• The cage is made from nylon with fiberglass fill 25% ( PA66 GF25)

LV (RV) series guide rail roller bearings: LV20/7 ZZ, LV20/8 ZZ, LV202-38 ZZ, LV202-40 ZZ, LV201 ZZ, LV201-14 ZZ, LV 201 ZZ, LV 201-14.2RS, LV 202- 41 ZZ, LV 203 ZZ, LV 204-57 ZZ, LV 204-58 ZZ, etc.

LV series bearings can be widely used in cylindrical guideways or 120°V-shaped guideways. Different from the LFR series rollers, the LV series bearings have strong adaptability to the size of the guide rail. Each specification can be adapted to a larger range of guide rail diameters and can be widely used in heavy-duty guides, mobile equipment, straightening machinery, etc.
JPG bearing adopts the internal structure design of double row angular contact ball bearing and the thickened outer ring, so that the bearing has a higher load carrying capacity.
JPG bearings are made of high-quality bearing steel (AISI52100 or stainless steel AISI440C), processed by heat treatment and precision grinding, and filled with long-life, high-quality, multi-purpose grease. Metal dust cover is adopted for bearing dust prevention.
The V-shaped groove bottom of the outer ring of JPG bearing has undercut grooves. If undercut grooves are not allowed in the use requirements, bearings without undercut grooves can be ordered from JPG bearings, and bearings with other V-shaped angles can also be customized. (Inventory)

The guiding system using the LV series guide bearing has the following characteristics:
1. Low resistance, long life, wide application: The V-shaped surface of LV series guideway bearings is finely ground, and the surface roughness reaches Ra0.32. The V-groove of the bearing has good parallelism with the installation plane of the inner ring. When working, the force between the bearing and the cylindrical guide rail is stable and the friction resistance is small.
2. Simple and convenient installation: After the bearing is equipped with an eccentric shaft and a concentric shaft, the installation is very convenient, and the eccentricity of the eccentric bearing can be adjusted to obtain a suitable preload.

Guide Wire Straightening Wheel Track Roller Bearing

The scope of application of the straightening wheel : cables, steel bars and steel wires undergo gradual and continuous straightening and shaping to obtain the final product. Reasonable operations in different steps for coils or coils and unnatural shapes.
Therefore, for each step of production, the turning process must be completed by its material support part. At this time, the straightening and shaping operation starts. Specifically, it can be divided into three steps:

1. Straightening, returning the material to its original shape, this step is completed by the first few guiding straightening wheels.

2. Remove the residual form of the material body due to the reel. This step is completed by the guided straightening wheel located in the middle of the straightening machine.

3. The last few guiding straightening wheels of the straightening machine complete the forming of the steel wire. Generally, the placement angle of these guiding straightening wheels   is the same as the first few guiding straightening wheels. 90 degree angle.

Usually these three steps should be combined. The reason is that the straightening machine uses 5, 7, 9, 11 or 13 guide straightening wheels on the two planes.
The manufacturing accuracy of the guide straightening wheel has a major influence on the quality of the final product (wire) and the service life of the guide straightening wheel. Therefore, the V-shaped correction groove on the outer ring should be in line with the guide The other parts of the straightening wheel have the same geometric characteristics and accuracy, which is very important. For this reason, the V groove of the Yitong guide straightening wheel is guided to the straightening wheel. It has been precision processed before assembly. It is dangerous to grind this groove on an assembled guide straightening wheel, because the roller may be damaged, so uniformity and geometric accuracy cannot be guaranteed. The service life of the straightening wheel will be shorter, and the quality of the wire drawing will also be impaired.

W (RM, VW) guide roller series guide roller: guide roller bearing is W type roller: W (RM) 0, W (RM) 1, W (RM) 2, W (RM) 3, W (RM) 4 , W(RM)0X, W(RM)1X, W(RM)2X, W(RM)3X, W(RM)4X, W(RM)4XL, W4XXL, W(RM)1SSX, W(RM)2SSX , W(RM)3SSX, W(RM)4SSX.

The application of guide rollers-the main components in the W (RM) type roller guide system are widely used in industrial robots, cutting equipment, moving guides, production lines, etc.

• The outer ring of the guide roller bearing is a W-shaped outer surface composed of two 90-degree V-shaped. The inner or outer side can be used alone to adapt to a 90-degree inner V-shaped or outer V-shaped guide rail, or the inner side can be used to adapt to a cylindrical guide rail.
• The guide roller adopts the internal structure design of double row angular contact ball bearings and the thickened outer ring, which makes the rollers have a higher load-bearing capacity.
•The guide roller is made of high-quality bearing steel, processed by heat treatment and precision grinding, and filled with long-life, high-quality, multi-purpose grease. The roller dust-proof adopts metal dust-proof cover or rubber sealing ring (suffix X). Our company can also provide rollers with concentric sleeves and eccentric sleeves, and can also provide rollers made of corrosion-resistant stainless steel.

The guiding system of W(RM) series guide rail rollers has the following characteristics:

1. Low resistance, long life, wide application
The working surface of the W(RM) series guide rollers has been finely ground, with good roughness and an accurate 90-degree angle. The W-shaped groove of the roller is parallel to the installation plane of the inner ring. When working, the force between the roller and the guide rail is stable, and the friction resistance is small.
2. Simple and convenient installation
After the eccentric sleeve and concentric sleeve are configured on the guide rail roller, the installation is very convenient. Adjust the eccentricity of the eccentric roller to obtain a proper preload.
