TIK linear ball bearing is consisted of an outer race, retainer, balls and end rings. The retainer is incorporated inside the outer race, and has three or more rows of elliptical ball tracks that allow unlimited ball circulation and the balls circulate very smoothly in those ball tracks. The retainer is held by two end rings at both ends of the outer race. One side of the paralleled straight portions of the elliptical ball track is cut off open, and the balls there are in contact with the shaft surface to circulate to and fro unlimitedly in the ball track according to the rectilinear reciprocation of the shaft. Thus the retainer forms rolling tracks, and at the same time keeps the balls from falling out when the bearing is removed from the shaft.
The TIK linear ball bearings are high precision bearings manufactured with its own technology and have the following features. Features The TIK linear ball bearing has the outer race that is processed by cold press forming to shape the ball tracks. This gives features to its appearance, too. The cold press forming has enabled lightweight structure of the bearing. This eventually provides compact and lightweight machine design. The balls circulate endlessly. This structure provides unlimited stroke with minimal frictional resistance that ensures long service life and energy saving. The frictional resistance remains almost unchanged, even when the load increases. Therefore, heavy load is acceptable depending on application conditions. Because of the cold press forming for the outer race, an early failure caused by moment load and excessive pre-load can be prevented. The TIK linear ball bearing is heat treated in such a method as to suit to the outer race that is cold pressed formed. The TIK linear ball bearing with steel retainer is resistant against high temperature and applicable up to 150 C when it is without seals. Please consult TIK on use outside the recommended temperature range. The TIK linear ball bearing is interchangeable. The eccentricity is small and centering is easy. It can operate with simple lubrication or without any lubrication, depending on applications. Thus maintenance is almost free.
