Powder metallurgy spline bushing is used in: packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, various types of machine tools and interchangeable mechanical transmission connections. Features: large torque, high precision, convenient and quick assembly and disassembly, simple operation, good positioning, reducing the scrap rate of the mated shaft and hub, reusable, and no damage to the mating surface, it is currently the most ideal and economical choice.

1. Installation: Powder metallurgy spline bushing has been lubricated at the factory and can be installed and used directly. When installing, firstly screw three bolts into the screw holes of the flange of the other part, evenly distributed along the circumference, and push the inner sleeve and outer sleeve apart. Then put the expansion sleeve into the hub hole of the design position, and use a force measuring wrench to tighten the bolts. The tightening method is that each bolt is only tightened to 1/4 of the rated torque at a time. The tightening sequence is bounded by the opening. Left and right cross symmetrically and tighten in sequence to ensure that the rated torque value is reached.
2. Disassembly: When disassembling, loosen all the bolts for a few turns. Then screw the bolt top expansion sleeves crosswise into the disassembled screw holes.
3. Protection: Prevent Powder metallurgy spline bushing pollution during installation. In open-air operations or machines with poor working environment, anti-rust grease should be regularly applied to the exposed end faces and bolts of the expansion sleeve, and the type of expansion sleeve with better rust resistance should be selected. The expansion joint sleeve is a modern new type of advanced mechanical basic parts. It is a new type of keyless coupling device that is widely used in today's world to realize the connection between mechanical parts and shafts.
