name      Said:RType lock nut/cap

product      Card:Sweet/SWIFT

type      Number:SWT/Rseries

Product features: RType locking copper and thread showing30°The angle design does not bear the axial load on the thread. When the nut is locked, the screw thread will not release the axial load, and the nut will not deform. Three equal spacing locking copper can be used to adjust the deviation of the other parts that will be installed on the shaft. Because of locking, copper will not deform,FThe nut can still maintain density after many times of disassembly and assembly.

material       Quality:42CrMo42CrMoSteel belongs to ultra high strength steel, high strength and toughness, hardenability is also good, no obvious temper brittleness, after quenching and tempering treatment have high fatigue limit and anti shocksand low temperature impact toughness. The steel is suitable for manufacturing large and medium-sized plastic mould with certain strength and toughness

R Type andF Type lock nuts are very easy to install. There are grooves on the circumference, and different types of spanners can be chosen according to the size of the application and the nut, including hook spanner and impact wrench( chart3). The corresponding dimensions of the wrench and key (for flat headed screws) are given in the product table.

Lock it upR Type andF Type screw nut should be gently fastened to the end screw until the thread of the locking pin engages the shaft thread. Then tighten the flat head screws alternately and evenly until the tightening torque listed in the product list is reached.

Misalignment must be corrected thread bearing surface and adjacent elements, should first flat screw loose in the maximum deviation position and the other two screws to the same degree. Then loosen the loosened screws. If this correction is not enough, the program should be repeated until the required accuracy is achieved.

Disassemble

In disassemblyR Type andF Remember that the locking pin is still engaged with the shaft thread even after the flat head screws have been loosened. The pan head screws with a rubber hammer tap near the nut and the locking pin can be loose, then you can easily unscrew nuts from the shaft thread.
