Back-up rings have been used in conjunction with O-rings in high pressure applications. A back-up ring is a rigid ring that holds an elastomeric seal to its designed shape and in its correct place. Back-up rings are most commonly used with O-rings to prevent extrusion at high pressures. When sealing the piston inside a pneumatic cylinder, a soft and flexible material is required to prevent leakage, but those same properties may leave the seal material vulnerable to being pulled out of its seat and then pinched or torn in the narrow space between piston and cylinder wall. If the joint cannot be redesigned, or a more resistant elastomer used, then the solution may be direct reinforcement with a stiffer material - in the form of a hard inner ring in this case. In general terms, for dynamic applications over 100 bar, and static applications around 900 bar, back-up rings should be used. Seal Materials: PTFE (Virgin Teflon). Temperature Range: -50C + 200C Pressure: up to 800 bar (80Mpa) O Ring material: Nitrile, Viton. Size Range : We manufacture PTFE Back up Rings for upto 700mm cylinder bore & Rod diameter as per International Standard Size Chart. Fields of Application : The use of backup ring is must when any of the following operating conditions are present in a hydraulic cylinder. when pressure is above 100 bars (10Mpa). Extreme and frequent pressure variation. Large tolerances between the components to be sealed or large radial sealing gap. High temperatures above 120C.

Cone crusher spare parts Cone crusher is widely used in application industry, such as metallurgy, construction, mining, etc. It can be used as two or three broken, four broken. Hydraulic cone crusher, compound cone crusher and spring cone crusher various consumable parts are collectively referred to as the cone crusher. Cone crusher parts include mantle bowl liner socket liner and other bushing. Metso spare parts include: Upper head bushing,lower head bushing,thrust bearing,eccentric bushing,socket liner ,piston plate.etc. All these bronze parts are imported wear parts of metso spare parts. The role of this bronze bushing is slide bearings,which have an irreplaceable role in the cone crusher. Model : Metso C series jaw crusher: C80 C100 C110 C125 C140 C160 C200 Metso (goldberg) GP series crusher : GP100,GP110,GP300,GP500 Metso (goldberg) HP series crusher :HP100,HP200,HP300,HP400,HP500,HP700,HP800 etc Assembly show: Processing and Machining¡ê» Our metso spare parts (bronze) adopt centrifugal casting process. By centrifugal casting, density, high strength, no stomata trachoma, the service life of two to three times that of ordinary sand mold casting, can be customized according to user requirements of various national standard and non-standard material Package How to replace the cone crusher spare parts :bronze bushing 1.Eccentric bushing After locking filler hole drilling broken, then the eccentric bushing upside down, you can remove the bushing. Before installing the new one , you must check whether the eccentric sleeve hole size cracks. When installing copper eccentric bushing , available in dry ice cooling. When pouring locking filler, eccentric and copper bushing must be at a temperature of about 70 degrees, eccentric and copper sleeve hole must be positive. 2. Upper head bushing and ower head bushing Lower head bushing can be cut out, but make sure not to damage the moving cone bore. upper head bushing can pull, and can be cooled with dry ice to speed up the pull-out speed. Dry ice can be used when installing copper cooling head bushing, at least 2 hours each, when fully cooled after, with its rings lift copper bushing, from under the rings to use flat gaskets to ensure dynamic cone copper sleeve edges and bottom edge parallel. 3. Countershaft bushing Outer copper bushing sheath pulled by homemade devices removed within the copper sleeve can be removed using a center rod means hammering out the copper sleeve split out, you need to check the size of the hole in the creel is reasonable. When installing the countershaft bushing, use dry ice shrink at least 2 hours
