Product Description

honed tube SRB /honingtube

The hydraulic cylinder tube is the main part of the hydraulic cylinder.The inner hole of the hydraulic cylinder tube usually precision processed by boring,reaming,rolling or honing.By these process can ensure the piston,sealing elements and the support elements move smoothly,then ensure the sealing effect and reduce the abrasion.The hydraulic cylinder tube will bear big pressure,so need high strength and stiffness.

(honing tube) precision tube.
Main materials: 20#, Q235, 20G, 35#, 45#, 16Mn, Q345, 40Cr, 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo, 42CrMo.Widely used: engineering machinery, metallurgical machinery, plastic machinery, opening and closing machinery, mining machinery, road construction machinery, textile machinery and other industries.1. Cold rolling 2. Cold drawing 3. Honing.

SRB tube (skived rolled burnished)

1, the processing time is greatly shortened. The pipe that honed 30 minutes before is rolled out in a few minutes.
2, the surfurface hardness of the roller is harder than the surface of honing, and it also improves the service life.

3, the finish of the processing surface is improvedace h.
4, the processing cost is saved. After honing and grinding, the grinding is made of mud. The remaining materials are filamentous and can be recovered later.
