We understand that two logins is an inconvenience and are working to consolidate our systems into one login process. Until we’re able to consolidate the two logins, please follow these guidelines:
Quando un dado in plastica semplicemente non ce la fa, Thomson BSA offre i dadi in bronzo standard . I dadi di bronzo possono sopportare carichi maggiori dei dadi in plastica, rendendoli perfetti per le applicazioni con carichi alti. Thomson BSA usa i cuscinetti in bronzo SAE 660 che fornisce un'eccellente capacità di carico, buona resistenza all'usura e minore sensibilità ai danni da impatto e da carichi impulsivi. Se richiesto, si può selezionare anche un bronzo particolare. Per prestazioni ottimale, usare sempre il nostro lubrificante TriGEL-600SM per ridurre l'attrito e permettere al nostro sistema di lavorare al meglio.
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.
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.
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.
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.
