stripsguide Tapes The function of a hydraulic wear ring is to guide the shaft and hole sealing of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system. DST has a rectangular cross-section with rounded or chamfered edges, thus preventing impermissible edge force in the corner radius of the grooves. The chamfers also serve to facilitate installation, e. g. When inserted into the cylindrical tube or guide bush. Embossing structure -The thickness of PTFE guidance tape is greater than or equal to 2mm can be supplied with embossing. -Embossing structure is the sliding surface which with small lubrication micro cavity, which can promote the formation of a lubricant film, improve the micro-lubricating, embedded micro foreign matter, and help to protect the seal system. -In consideration of the guidance tape can be used for piston and rod. -Wear strips are generally made into a double-sided embossing. -Our embossing have 4 types of pattern, including teardrop structure, round point pattern, diamond pattern and coin pattern. -Please feel free to contact us if you need more details about our factory and/or products.
