Bronze Cylinder Guide Sleeve for Hydraulic Piston Rods
Product Introduction
Cylinder Guide Sleeve is a guide and sealing component used in hydraulic or pneumatic systems.
The High Precision Bronze Cylinder Guide Sleeve is a vital component in hydraulic systems, designed to ensure smooth and accurate movement of the piston rod within a hydraulic cylinder. Made from high-quality bronze materials such as CuSn8 or CuAl10Ni, this guide sleeve provides excellent wear resistance, low friction, and long service life.
It functions as a guiding element to reduce side loads, protect the sealing system, and maintain piston alignment, making it an essential part of any heavy-duty or precision hydraulic cylinder assembly. Its high dimensional accuracy and thermal stability allow it to operate reliably even in extreme environments.
Product Description
The cylinder guide sleeve plays a guiding and supporting role on the piston rod, which requires high matching precision, small friction resistance, good wear resistance, and can withstand the pressure, bending force and impact vibration of the piston rod. The inside is equipped with a sealing device to ensure that the cylinder is sealed by the rod cavity, and the outside is equipped with a dust ring to prevent impurities, dust and moisture from being brought to the sealing device and damaging the seal.
Metal guide sets are generally made of bronze, gray cast iron, nodular cast iron and oxidized cast iron with small friction coefficient and good wear resistance; Non-metal guide sleeve can be made of polytetrafluoroethylene and polytrifluorochloroethylene, etc.
