Closed Guide Bush with Stop Rings N 552

Product Information

Suitability

Design as for N 550, with stop rings fixed on both sides.
• When used in combination with shaft diameter d_w ISO-h3, preloading of the rotary stroke bearings is guaranteed.
• The stop rings ensure the cage is effectively restricted for linear and rotary movements.
• Smooth running of the rotary stroke bearing is not impaired by the stop rings.

Features

• Stop rings fixed on both sides.
• The closed guide bush and integrated ball cage form a separate component.
• Guide bore diameter d₁ is finely honed to ISO tolerance IT 3, R_z 0.5 – 1.5 μm 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.
• Outside diameter d_B n4 with radial run-out error within IT 4, ground to guide bore diameter d₁, lead-in taper on one side.
• The maximum stroke path H_max is determined from the length of guide bush l₃ and the length of the ball cage l₂: H_max = 2 (l₃-l₂).
• 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
• Steel stop rings

Special designs

Other dimensions or designs based on workpiece drawings are available.
These can also be produced using stainless steel (1.4112).
