To provide the products with high quality, the source of material and the treatment before shipping is important. Thus, the LFR series Linear Motion Bearings are made of high-quality bearing steel, processed by heat treatment and precision grind, and are filled with a long service life, high-grade and multi-purposes grease, mount the metal shield (KDD) or rubble seal (NPP) to prevent the dust.

For series LFR rollers, the surface profile of the outer ring is designed as the GOTHIC ARCH. When rollers run, there are two contact points with an angle of 60 degrees between the roller and track. Hence the friction resistance appears low and the load is in equality, thus avoiding the stress 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. As linear motion bearings assembled the concentric or eccentric pivot, installation can be made convenient. To adjust one’s eccentricity, these rollers can get the fitting preload. 

■ Characteristics of the guide system that series LFR rollers are applied :

1. High allowable speed, low resistance, long service life
For 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 installation
As 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.

3. Smooth running, minimum error and lower noise level
YITONG special manufacture equipments of machine and inspection facilities make accuracy in the profile of roller. Mature manufacture techniques and critical inspection procedure make all rollers good in the Kea (radial runout) of outer ring and roundness of working surface, so the guide system in motion is smooth running, minimum error and lower running noise level.

Most of the double row cam rollers can be relubricated through the filling hole on the inner ring to adapt the adverse working conditions.
2. Easy installation
After rollers assembled the concentric or eccentric pivot, installation can be made convenient. To adjust the eccentric one's eccentricity, the rollers can get the fitting preload.
3. Smooth running, minimum error
Besides we produce the series LR cam rollers according to the standard of rolling bearings, we also make the strict control on the rotary accuracy of outer ring in order to meet special working mode that inner ring is fixed while outer ring running.

1. Low resistance, long service life, widely-use
Being cam rollers with crowned runner surface R500, make its stresses in well-distributed between rollers and track when working, thus the stresses centralization are avoided, the friction resistance are reduced and the service life of rollers have been improved a lot. Most of the double row cam rollers can be relubricated through the filling hole on the inner ring to adapt the adverse working conditions.
2. Easy installation
After rollers assembled the concentric or eccentric pivot, installation can be made convenient. To adjust the eccentric one's eccentricity, the rollers can get the fitting preload.

• YTGW 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 track is in equality and the friction resistance is low.

2. Easy installation
After wheels assembled the concentric or eccentric bushing, installation can be made convenient. To adjust the eccentric one's eccentricity, the wheels can get the fitting preload.

Friction
The roller guides have a very low coefficient of friction. This value is slightly increased by the fitting of wipers to the rails.

Corrosion resistance 
Elements of the series with the suffix ..R are available in stainless steel.

Adopting carefully chosen materials and components :
YITONG track rollers are made of the high-quality bearing steel (SAE52100) or stainless steel (440C) from the Shanghai No.5 Steel Company, so they possess of a favorable mechanical function after heat treatment. We select the precision steel ball of TSUBAKI from Japan to better the function of products. Meanwhile, the cage made of the engineering plastic from DUPONT or high-quality steel sheet (SPCC-SD) makes the bearings run in the reliable condition. The standard rollers are filled with the high-grade and multi-purpose grease from the SHELL Company and mantled by the Buna-N rubber seal or metal shield made of the high-quality steel sheet (SPCC-SD), so that to ensure that products can be lubricated well with the excellent function of seal and dustproof. It is available to fill with the specified grease and to mantle the high-quality rubber seal for custom products in order to meet different applications, such as KLUBER Grease from Germany, heat-resisting fluorin rubber seal and so on.

Optimal design :
Various series of all YITONG Track Rollers have a section that suit for running on the track. For example, the Gothic arch groove profile suit to cylindrical track. So the force distribution can be shared out equally and the load carrying capacity is increased in the rollers.

For the system or equipment that the track needs a low wear requirement, YITONG adopted a special design of two different hardness grades, i.e. the hardness of internal structure is the standard one to ensure the roller’s service life to be longer, while the hardness of external is lower than the track’s. So the track abrasion is reduced, which makes the maintenance convenient and its cost lower.

Advanced technique :
YITONG special equipments of machine and facilities as well as inspection methods make the special profile design of bearing precisely on the products. For example, the accurate “V” and “W” profiles can make roller well contact with the track to improve the stability and prolong the service life of the system. Thus, the actual loads of roller can be met to the designed requirements.
