The Gamma Seal 9RB 110x132x5.5/7.5 is designed primarily as an external contamination exclusion seal rather than a conventional oil-retaining rotary shaft seal.

The seal consists of a metal outer ring combined with a flexible elastomer sealing element that creates axial contact against a stationary counter face. This design forms an effective barrier against dust, moisture, mud, sand, and airborne contaminants that may damage bearings and internal sealing systems.

Gamma Seals are commonly installed in front of primary oil seals to significantly increase bearing protection and overall sealing system reliability. They are widely used in harsh operating environments where contamination is a major cause of equipment failure.

The compact design allows easy installation while providing reliable protection under shaft misalignment, vibration, and continuous-duty operation.

With dimensions of 110 x 132 x 5.5/7.5 mm, this seal is suitable for industrial equipment, agricultural machinery, mining equipment, conveyors, electric motors, gearboxes, and OEM rotating machinery.
