Product Description

The YZ-DD and YZ-DC series hydraulic swivel joints are engineered for high-pressure, low-frequency rotation and swinging applications. Constructed entirely from high-grade stainless steel, these compact and easy-to-install adapters ensure exceptional durability and corrosion resistance. Large specifications are equipped with oil-free composite bearings to guarantee smooth, maintenance-free operation. Designed to perform reliably in normal-temperature hydraulic oil circuits, they feature a maximum pressure rating of 20.5 MPa and serve as a direct, drop-in replacement for Frishton rotary joints.

Key Features

Stainless Steel Construction: Full stainless steel body provides superior rust and corrosion resistance, ideal for harsh industrial environments.
Oil-Free Bearings: Large sizes utilize oil-free composite bearings, reducing maintenance needs while ensuring smooth low-speed swinging.
Space-Saving Design: Compact structure allows for convenient installation even in tight machinery layouts.
Direct Replacement: Perfectly matched to replace Frishton rotary joints, minimizing downtime and retrofitting costs.
Extreme Condition Ready: Built to withstand ultra-low temperatures, high pressures, and aggressive media.
