Ultra Heavy Duty Ball Screws
To increase the load capacity of ball screws, the numbers of effective balls has to be increased. This also increases the friction between each contacting ball. Due to this situation the number of balls per each circuit has to be limited and the number of circuits applied to the ball nut must be increased. Tsubaki’s newly developed ultra heavy duty ball screw with retainer can eliminate friction and increase the number of effective balls by implementing a new re-circulation system. This will increase load capacity and is also suitable for oscillation movement. Features: - Heavy load can be applied. - Load capacity is max. 2 times that of standard high load capacity ball screws. - Stiffness is max 1.5 times the stiffness of a standard ball screws. - UHD series ball screws can be made suitable for any oscillation movement by using retainers. - Length of the nut can be reduced, if the required capacity is the same. - The shape of the ball nut is compact and uniform.

Precision Ball Ways with Retainers
There has been an increased improvement in the precision machine industry. The demand for high speed, high rigidity, low noise and maintenance free linear motion guides is now required. With Tsubaki's long history and state of the art technology, we have developed a retainer for Ball Ways. Features: - (Smooth Movement) The lack of friction by retainers reduces variation sliding resistance. - (Low Noise) Retainers stop ball to ball impact of rotating balls thereby offering low noise. - (Oscillation) Retainers provide even spacing of balls which allows for smoother operation especially under oscillation movement. - (Durability) The lack of friction between balls by retainers reduces heat and improves efficiency and the life of the ball way. - (Rigidity) Under the same preload (sliding resistance), new ball ways can achieve high rigidity of comparable linear motion guides. - (Effect of Holding Lubrication) Retainers assist in controlling lubrication lost by holding lubrication. Retainers achieve long term maintenance free life. - (Price) Only 10% higher than regular ball screws. - (Seals) High performance seals are available as an option.
