Open Guide Bush
N 550

                 Suitability

                 Open guide bush with tapered inside edges on both sides.
                 • Allows universal use.
                 • When used in combination with shaft diameter dw ISO-h3, preloading of the rotary

                  stroke bearing is guaranteed.
                 • The ball cage can project out of the guide bush on both sides. This permits long stroke

                  paths even with short guide bushes used in combination with long ball cages (note
                  minimum contact length).

                 Features

                 • Guide bore diameter d1 is finely honed to ISO tolerance IT 3, Rz 0.5 – 1.5 m
                  depending on diameter.

                 • Roundness within 1/3 ISO-IT 3.
                 • Cylindricity within IT 1.
                 • Radial run-out of a shaft inserted under preloading is within 0.0005 mm.
                 • Tapered inside edges on both sides ensure smooth running.
                 • Outside diameter dB n4 with radial run-out error within IT 4, ground to guide bore

                  diameter d1 lead-in taper on one side.
                 • See page 37-41 for instructions on installation and servicing.

                 Material

                 • Special roller bearing steel 100 Cr 6 (1.2067 or 1.3505)
                 • Carefully heat-treated, hardness rating HRC 60–64/HV 720–815
