Thomson의 SNAB 나사산 장착형 디자인은 설계 유연성이 우수하여 1인치 직경을 통해 안티 백래시 어셈블리가 가능합니다. 매우 단순한 디자인으로 자주 모방됩니다. XC 시리즈 리드 스크루 너트보다는 약간 덜 뻣뻣하지만, 카탈로그 사양에 있는 프리로드 무게까지 제로 백래시를 제공합니다. 모든 SNAB는 아세탈을 내부적으로 매끄럽게 만들어 탁월한 매끄러움과 매우 낮은 마모도를 제공합니다.

Dynamic Load (Ball Screws)
Dynamic load rating is the maximum load which a ball bearing screw assembly can maintain for 1.0 million inches of travel (Inch Series) or 1.0 million revolutions (Metric Series).
Design Load (Lead Screws and Glide Screws™)
Maximum load at which a lead screw assembly should be operated. Not applicable for life calculations.
The nominal outside diameter of the screw shaft for a screw only. For a nut it is the nominal outside diameter of the mating screw.
The axial distance a nut travels from one revolution.
The direction of threads on a shaft or in a nut. Left hand means that the nut will move away if rotated counterclockwise. Right hand means the nut will move away if rotated clockwise.
The axial free motion between the nut and screw is called backlash. An Ant-backlash nut is designed to reduce or eliminate this movement.
Lead Screw
The lead screw assembly converts rotary motion to linear motion. The lead nut slides over the thread of the screw. Thomson lead screws excel in applications which require the “just right” solution.
Ball Screw
The ball screw assembly converts rotary motion to linear motion with recirculating ball bearings. Ball screws have a very low friction coefficient and is typically greater than 90% efficient.
Glide Screw™
Part linear bearing, part lead screw, the Glide Screw™ from Thomson combines the best features of these products into an easy to install, one-part solution.
