Characteristics of YITONG track rollers

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.
