There are various sizes of LM Guideways and Ballscrews available in the standard series. Numerous applications require numerous sizes and shapes of LM Guides and Ballscrews depending on space, loading capacity, working, and well as mounting. Miniature LM Guideway (MSC / MSD): The miniature guide series starts from size 5 up to 15 with 4 types of variants. MSC and MSD have a Gothic-arch groove and designed to contact angle…

The full roller type linear guideway, MSR series, equipped with rollers instead of the ball, and therefore the MSR series can provide higher rigidity and loading than the normal type with the same size. Especially suit for the requests of high accuracy, heavy load, and high rigidity. Characteristics Ultra Heavy Load: MSR linear guideway through rollers has a line contact with carriage and rail. Relative to the general type linear…

One of the important features of the LM Guideway is its capacity to carry heavy loads. The optimum design of geometric mechanics makes the linear guideway to bear the load in all four directions, radial, reversed radial, and two lateral directions. There are 2 major considerations to be accounted for while selecting the suitable LM Guide, those are as below: Static Load Rating A localized permanent deformation will develop between…
Read MorePreloading in Ballscrew & LM Guideways
What is Preloading and why it is done? Preload is the elimination of internal clearance between the rail and carriage or between the ball screw and ball nut. This makes the system more rigid by creating a load on the linear guide or ball screw, which reduces deflection when an external force is applied. Preloading is used to increase the accuracy and rigidity of a ball screw system. It makes the…
Read MoreBallscrews
A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. They are made to close tolerances and are therefore suitable for use in situations in which high precision is necessary. The ball assembly…
