ALTA finishing

From our earliest days in 1968, ALTA has been the epitome of excellence, the choice of the finest materials and the unique manufacturing of their surface finish.

Through our inside finishing production process we achieve an RA profile characterized by exclusively negative micro picks, these are generating small oil pockets in the surface, improving the system lubrication allowing an optimal bearing surface to improve seal life for a longer period.

Furthermore our production process gives a better performance on inside straightness against the maximum tolerances allowed by the norms and the profile bearing goes over 50% at 1 my depth.

Finally ALTA has an automated patented system scanning the tube surface after machining, able to detect any possible micro surface defects
