1. Before assembly shall ensure that no foreign body, shaft sleeve, seat hole surface pore surface should be bright and clean as far as possible in order to avoid scratch during assembly.
2. When assembling outside the shaft sleeve surface coated with lubricating oil, appropriate help shaft sleeve is convenient to install, but not too much to avoid the overloading or when the reciprocating motion shaft sleeve will be out.
3. With core shaft assembly should be slowly pushed (recommend the use of hydraulic press), banned direct knock deformation of shaft sleeve.
4. When a hole design for easy deformation of materials or a hole wall thickness is thin, please make this clear, to make a hole deformation in order to avoid being connected.
5. In order to make the assembly easier and won't destroy wear-resisting layer, axial end face must have a chamfer, smooth shaft material Suggestions for bearing steel surface hardening treatment HRC45, surface roughness for Rz2-3, surface can also be hard chrome plating.
6. You have possible assembly, please in the shaft surface coated with grease to shorten the sleeves running-in period.
