Models SSR-XW and SSR-XWM W B Outer dimensions Model No. Height Width Length Grease nipple Note) The M in the model number symbol indicates that the LM block, LM rail and balls are made of stainless steel. The stainless steel provides excellent corrosion and environmental resistance.

(*2) See A1-71. (*3) See A1-77. (*4) See A1-13. Note) This model number indicates that a single-rail unit constitutes one set. (i.e., required number of sets when 2 rails are used in parallel is 2 at a minimum.) Those models equipped with QZ Lubricator cannot have a grease nipple. When desiring a grease nipple for a model attached with QZ, contact THK. Download data by searching for the corresponding model number on the Technical Support site.
