Custom Cylinder Guide Sleeve For Hydraulic Systems
Product Introduction
Custom Size Cylinder Guide Sleeve is a high-performance hydraulic component tailored specifically for the rugged demands of construction machinery and heavy-duty equipment. Engineered for precision and durability, this guide sleeve ensures accurate piston rod alignment and protects critical internal parts of hydraulic cylinders from side-load stress, excessive friction, and premature wear.
Unlike standard off-the-shelf components, this guide sleeve is fully customizable in diameter, length, material, and surface finish, making it ideal for original equipment manufacturers (OEMs), hydraulic service companies, and maintenance teams working with non-standard or oversized construction equipment cylinders.
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.
