Industrial UCC 18221-1 Gland Ring

Description:

The UCC 18221-1 Gland Ring is an industrial mechanical retaining component designed to provide secure sealing, alignment, and retention within heavy-duty hydraulic cylinders, mechanical assemblies, and industrial equipment. Commonly installed in hydraulic actuators, construction equipment, mining machinery, material handling systems, and OEM industrial machines requiring a precision-machined gland ring. Maintenance technicians, equipment rebuilders, and system integrators use this gland ring for equipment repair, preventive maintenance, and replacement of worn OEM sealing components to ensure reliable operation and extend equipment service life. The component is manufactured from heat-treated 4140 alloy steel for high strength and wear resistance.

Applications:

The UCC 18221-1 Gland Ring is commonly used in hydraulic cylinder assemblies, heavy equipment, mining and construction machinery, industrial presses, lifting equipment, and power transmission systems where accurate shaft guidance, seal retention, and structural support are required. Its hardened alloy steel construction provides durability for high-load and continuous-duty industrial applications.
