The slim body saves installation space while keeping uniform radial pressure on shafts, featuring easy assembly and good concentricity for compact machinery.To maximize performance in narrow groove configurations, the MKC R-series includes specialized micro-precision engineering forms, such as:

Standard Thin-Profile Series: RB (Engineered with an outer metal case and a single spring-assisted lip, offering ultimate axial space savings and superior press-fit alignment for precision hardware).

Applications
