SSA series guideways can be classified into rectangular and flange types. The sizes are various(15mm,20mm,25mm,30mm,35mm,45mm). And their accuracy can reach up to UP(Ultra precision) class.
Self-aligning capability
By design, the circular-arc groove has contact points at 45 degrees. SSA series can absorb most installation errors dueto surface irregularities and provide smooth linear motion through the elastic deformation of rolling elements andthe shift of contact points. Self-aligning capability, high accuracy and smooth operation can be obtained with an easyinstallation.
Interchangeability
Because of precision dimensional control, the dimensional tolerance of SSA series can be kept in a reasonable range,which means that any blocks and any rails in a specific series can be used together while maintaining dimensionaltolerance. And a retainer is added to prevent the balls from falling out when the blocks are removed from the rail.
High rigidity in all four directions
Because of the four-row design, the SSA series Linear Guideway has equal load ratings in the radial, reverse radialand lateral directions. Furthermore, the circular-arc groove provides a wide-contact width between the balls and thegroove raceway allowing large permissible loads and high rigidity.
