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, MSB 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. B62

2 Compact, Fourway Equal Load Compact design of the carriage with 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 Low Noise The simplified design of circulating system with strengthened synthetic resin accessories makes the movement smooth and quiet. LINEAR GUIDEWAY Compact Type, MSB Series Self Alignment Capability The self adjustment is performed spontaneously as the design of facetoface (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. B63

3 C. Carriage Type Medium Load MSBTE Type MSBTS 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. Heavy Load MSBE Type MSBS Type All dimensions are same as MSBTE except the length is longer, which makes it more rigid. All dimensions are same as MSBTS except the length is longer, which makes it more rigid. B64

4 Ultra Heavy Load MSBLE Type MSBLS Type LINEAR GUIDEWAY Compact Type, MSB Series All dimensions are same as MSBE except the length is longer, which makes it more rigid. All dimensions are same as MSBS except the length is longer, which makes it more rigid. D. Rail type Counter bore (R, U type) Tapped Hole (T type) B65
