Rear Seal Retainer Bushing

Engineered as a durable aftermarket solution for drilling equipment, the Rear Seal Retainer Bushing (OEM N78109) is intended for maintenance of compatible Soosan drill rigs, drifters and support systems. Its primary role is to contain hydraulic oil, air or flushing media while keeping dirt and abrasive contamination away from critical interfaces. The compatibility data covers applications such as TD-51.

For long-term reliability, the part is designed around repeated pressure cycles, reciprocating or rotary movement, temperature changes and contamination typical of drilling service. With application-matched sealing materials and accurately controlled profiles, the component is intended to install accurately and work predictably with adjoining parts. This supports stable sealing performance, cleaner operation and longer service intervals for the surrounding assembly.

Offered within Delkom’s aftermarket portfolio for drill rigs and drifter systems, the part provides a practical option for repair planning and stock management. Use reference 160 100 135 for availability, bulk pricing and application support.
