Standard Hydraulic Dustproof Wiper 55×69×8/11 DKBZ Oil Seal Overview

For hydraulic cylinders operating in gritty, high-duty environments, rod contamination is a top cause of premature seal failure. The Standard Hydraulic Dustproof Wiper 55×69×8/11 DKBZ Oil Seal is engineered to keep dust, mud, moisture, and metal fines out of the system while helping retain a thin lubricating film on the rod. The 55×69×8/11 specification indicates a 55 mm rod interface, 69 mm housing outer diameter, and a stepped axial height for stable press-fit and lip geometry. The “DKBZ” design typically combines a reinforced outer case with a precision double-lip profile for dependable scraping and secondary sealing performance.

Depending on operating conditions, Hebei Hankai Machinery Equipment Co., Ltd. can supply the wiper in proven materials such as NBR or FKM elastomers and polyurethane (PU) for abrasion resistance, often paired with a metal-reinforced outer case for dimensional stability. Typical operating ranges cover low to moderately high temperatures and mineral oil–based hydraulics. Grooves are compatible with common metric cylinder housings, allowing straightforward drop-in replacement during overhauls. As a reliable manufacturer in the seal manufacturing segment, Hebei Hankai combines rigorous incoming material control, precision molding, and 100% visual inspection to deliver consistent performance across batches.

Benefits & Use Cases of Standard Hydraulic Dustproof Wiper 55×69×8/11 DKBZ Oil Seal in Seal manufacturing

In seal manufacturing and cylinder assembly lines, the Standard Hydraulic Dustproof Wiper 55×69×8/11 DKBZ Oil Seal is specified for rod ends of cylinders serving excavators, loaders, presses, injection molding machines, forklifts, and material handling systems. Its robust dust-exclusion performance protects rod seals and bearings from abrasive ingress, improving uptime and extending maintenance intervals. The double-lip DKBZ profile offers a positive wipe on rod extension and retraction, while the reinforced OD ensures a secure, concentric fit that resists popping during pressure spikes or rod side-loads.

Key advantages include high abrasion resistance (with PU options), chemical compatibility (NBR/FKM options), stable retention via metal casing, and low stick-slip behavior for smooth rod travel. For OEMs and rebuilders, the standardized 55×69×8/11 dimension helps simplify inventory and speeds assembly. Hebei Hankai Machinery Equipment Co., Ltd. supports engineering teams with prompt sampling, flexible MOQs for pilot runs, and technical guidance on groove geometry and surface finish to ensure the wiper’s full performance in demanding hydraulic and pneumatic power machinery applications.
