The SAKAGAMI S-LEEVE (WRB Type) Rod Packings are high-performance plastic bearings designed to function as both bearings and back-up rings for hydraulic sealing systems. Manufactured from durable polyamide (PN104), WRB-type S-Leeves are engineered to support rod packings while preventing metal-to-metal contact, seizure, and eccentric rod movement. Their one-piece groove installation simplifies assembly and enhances system reliability, making them ideal for hydraulic cylinders used in industrial machinery, construction equipment, and fluid power applications.
Designed for demanding operating conditions, WRB S-Leeves significantly improve pressure resistance and extend seal life by maintaining proper alignment of rods and pistons. Their precision-molded structure ensures stable performance under high loads, while compatibility with SKY-Packings and interchangeable sealing products adds flexibility for system designers. With excellent wear resistance and dimensional stability, these rod packings contribute to smoother operation, reduced maintenance, and longer service intervals.
