Characteristics The trains of balls are designed to a contact angle of 45 which enables it to bear an equal load in radial, reversed radial and lateral directions. Therefore, it can be applied in any installation direction. Furthermore, MSA series can achieve a well balanced preload for increasing rigidity in four directions while keeping a low frictional resistance. This is especially suit to high precision and high rigidity required motion. The patent design of lubrication route makes the lubricant evenly distribute in each circulation loop. Therefore, the optimum lubrication can be achieved in any installation direction, and this promotes the performance in running accuracy, service life, and reliability. igh Rigidity, Four-way qual oad The four trains of balls are allocated to a circular contact angle at 45, thus each train of balls can take up an equal rated load in all four directions. Moreover, a sufficient preload can be achieved to increase rigidity, and this makes it suitable for any kind of installation. Smooth Movement with ow Noise The simplified design of circulating system with strengthened synthetic resin accessories makes the movement smooth and quiet. Self Alignment Capability The self adjustment is performed spontaneously as the design of face-to-face (DF) circular arc groove. Therefore, the installation error could be compensated even under a preload, and which results in precise and smooth linear motion. Interchangeability For interchangeable type of linear guideway, the dimensional tolerances are strictly maintained within a reasonable range, and this has made the random matching of the same size of rails and carriages possible. Therefore, the similar preload and accuracy can be obtained even under the random matching condition. As a result of this advantage, the linear guideway can be stocked as standard parts, the installation and maintenance become more convenient. Moreover, this is also beneficial for shortening the delivery time. B28 eavy oad Type, MSA Series

4 C. Carriage Type eavy oad MSA-A Type MSA- Type MSA-S Type Installed from top side of carriage with the thread length longer than MSA- type. This type offers the installation either from top or bottom side of carriage. Square type with smaller width and can be installed from top side of carriage. Ultra eavy oad MSA-A Type MSA- Type MSA-S Type All dimensions are same as MSA-A except the length is longer, which makes it more rigid. All dimensions are same as MSA- except the length is longer, which makes it more rigid. All dimensions are same as MSA-S except the length is longer, which makes it more rigid. inear Guideway General Catalog B29
