Features of ball screw
■High Precision and High Reliability
The screw shaft and nut made of specially treated material are heat treated.
Grinding by excellent equipment is made at a specified temperature. The ball screws are manufactured through a consistent flow of processes from material and assembly to inspection to provide high precision and high reliability.
■Shorter Delivery Time and Lower Price
The standardization and quantity production of screw shafts and nuts allows delivery of lower priced products on shorter times.
■Shaft End Machining Finish and Expansion of Peripheral Parts
The shaft end machining finish is stand ardized along with an expansion of peripheral pafts including support units.
■Good durability and high transmission rate
The screw shaft and nut in contact through balls assures reduced abrasion and smoothness to provide higher transmission efficiency. Therefore the accuracy can be kept with smaller degradation even in prolonged use.
■Gothic arc groove
The Gothic arc groove is employed for the thread groove. For this groove,the axial clearance can be reduced. Even with one nut,the rigidity can be increased by making the clearance zero and preloading.
