Thomson currently has two account systems - one for the website and CAD model downloads, and one for e-commerce. 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 uma porca de plástico simplesmente não serve, a Thomson BSA oferece porcas de bronze padrão. As porcas de bronze podem suportar cargas significativamente maiores do que as porcas de plástico, o que as torna perfeitas para aplicações para carga pesada. A Thomson BSA usa lubrificação SAE 660 para bronze de mancal que oferece excelente capacidade de carga, boa resistência ao desgaste e menos suscetível a danos de impactos e cargas de choque. Se necessário, podem ser selecionados lubrificantes para bronze personalizados. Para obter o máximo de desempenho, use sempre nosso lubrificante TriGEL-600SM, para reduzir o atrito e fazer com que seu sistema funcione no máximo.
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.
Direção da rosca
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.
