Track Roller with Gothic arch Groove

Track Roller with Gothic arch Groove

Series LFR rollers are the most widely-use and economy product among the linear motion track rollers, and they can suit to the cylindrical track.There are two contact points between the roller and track, so the contact function is favorable.• Rollers feature double row angular contact ball bearing in its internal structure design and a thick-walled outer ring, so rollers can accommodate higher loads.• Rollers are made of high-quality chrome steel, processed by heat treatment and precision grind, and are filled with a long service life, high-grade and multi-purposes grease. Rollers mount the metal shield (KDD) or rubble seal (NPP) to prevent the dust.  “Motion Bearings” also can provide the rollers with concentric or eccentric pivot. Some types of the rollers can be made from the corrosion resistance stainless steel.Characteristics of the guide system that series LFR rollers are applied:1. High allowable speed, low resistance, long service lifeFor series LFR rollers, the surface profile of the outer ring is designed as the GOTHIC ARCH. When rollers running, there are two contact points with an angle 60 degrees between the roller and track. So the friction resistance is low and the load is in equality, thus avoiding the stresses concentration and edge effect caused by the error from installation and manufacture, making the track system has the characteristics of high speed, low energy consumption, long service life and minimum noise level.2. Easy installationAs rollers assembled the concentric or eccentric pivot, installation can be made convenient. To adjust the eccentric one's eccentricity, these rollers can get the fitting preload.

Track roller with “V” groove profile

Track roller with “V” groove profile

Series LV bearings can be widely used in the cylindrical track or " V " profile track with an angle of 120 degrees. Different from the series LFR bearings, series LV bearings are more adaptable to the different track sizes. Each type can be applied with a larger range of track diameters. They are widely used for the heavy-duty track, mobile equipment, wire straightening machine and so on.• Bearings take the internal structure design of double row angular contact ball bearings and have a thick-walled outer ring, so the bearings can accommodate higher loads.• Bearings are made of the high-quality chrome steel, processed by heat treatment and precision grind, and are filled with a long service life, high-grade and multi-purposes grease. Bearings take the metal shield to prevent the dust. Characteristics of the guide system that series LV bearings are applied:1. Low resistance, long service life, widely-uses The roughness of the " V " profile surface can be reached to Ra0.32 processed by precision grind. The bearings have well parallelism between the "V" profile groove and the mount planes of inner ring relatively. When bearings working, the stresses between the bearing and cylindrical track is in equality and the friction resistance is low.2. Easy installationAfter bearing assembled the concentric or eccentric pivot, installation will be convenient. To adjust the eccentric one's eccentricity, the bearing can get the fitting preload.

W series line track roller bearing

W series line track roller bearing

•Guide Wheels are the main components of the Linear Motion system, they can be widely used in the industrial robot, cutting machine, motion track, production flow and so on.• The surface of outer ring is the "W" profile formed by the two "V" with an angle of 90 degrees. The internal or external side face can be matched separately with the concave or protrudable track that both have a "V' profile with the angle of 90 degrees, and also the internal side face can be matched well with the cylindrical track.• Wheels feature the internal design of double row angular contact ball bearing and a thick-walled outer ring, so the wheels can accommodate higher loads.Characteristics of the guide system that series W wheels are applied:1. Low resistance, long service life, widely-use After precision ground, the roughness of working surface of the series W wheels is fine and the angle of 90 degrees is accurate. The wheels have well parallelism between the "W" profile groove and the mount planes of inner ring relatively. When the wheels running, the stresses between the wheel and the track is in equality and the friction resistance is low.2.

Wire guides and  straightening roller

Wire guides and straightening roller

The straightening, consisting of putting the material back into its original shape. The operation is carried out by the first straightening rollers to remove the residual constraint in the material, due to the winding on the bobbin. This operation is performed by the rollers located in the central part of the straightener.The forming of the wire carried out by the last rollers on the straightener, generally placed at an angle of 90°compared to the angle of the first rollers.Often it is necessary to combine these three steps. That is the reason why the straightener uses 5, 7, 9, 11 or even 13 rollers placed in two planes. The manufacturing precision of the roller has a major influence on the quality of the final product (wires) as well as on the service life of the rollers. It is therefore essential that the rectified "V" notch on the outer ring has the same geometric characteristics and precision as the rest of the bearing. Grinding this notch on an assembled standard bearing is risky, as the bearing may be damaged. An acceptable uniformity and geometrical precision can thus not be guaranteed. The service life of the roller is much shorter and the quality of wire drawing suffers accordingly. Among numerous applications using thread guides and straightening rollers.Field of Application: The straightening of cables, strips and wires is performed in steps with successive stages until the final product is obtained. To rationalize the handling between the different steps the material is stocked on reels or on bobbins and takes forms which are not natural. For every production step, it is therefore necessary to carry out the inverse process by taking the material off its support. At that moment, the straightening operation takes place. It may be divided into three steps: ■The following machines use the same type of special rollers:• Machine tools for fiberglass cables (lawn mowers)• Machines for spring manufacturing• Machines for metal wires• Machines for spooling, un-spooling and rewinding• Fine and high precision wire drawing
