The AEROQUIP Oil Seal 2.625x3.375x0.375 LGS NBR is designed for industrial rotary shaft applications requiring dependable lubricant retention around a 2.625-inch shaft.

Installed between the rotating shaft and stationary housing, the sealing element creates controlled radial contact with the shaft surface. This helps reduce leakage of oil or compatible grease while limiting the entry of dust, dirt, moisture, and abrasive particles into the bearing, gearbox, pump, transmission, or drive assembly.

The product is identified by the manufacturer-specific LGS Profile. Because industrial seal-profile codes may vary between manufacturers and production series, the exact sealing-lip geometry, number of lips, outside-case construction, internal reinforcement, spring arrangement, dust-exclusion feature, and installation direction should be compared with the original seal or technical drawing before replacement.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing element is generally compatible with:

• Mineral oils
• Gear oils
• Hydraulic oils
• Bearing grease
• Petroleum-based lubricants
• General industrial lubricating fluids

NBR provides good resistance to petroleum-based oils, grease, abrasion, and mechanical wear under standard industrial operating conditions. Compatibility should be confirmed before use with aggressive chemicals, high continuous temperatures, ozone-rich environments, or specialized synthetic lubricants.

The inch dimensions correspond approximately to:

Shaft diameter: 2.625 inches or 66.68 mm

Housing diameter: 3.375 inches or 85.73 mm

Seal width: 0.375 inch or 9.53 mm

The relatively narrow 0.375-inch axial width makes this seal suitable for compact bearing housings, gearboxes, pumps, transmissions, and OEM machinery using an inch-size rotary shaft-sealing arrangement. Accurate dimensional measurement and LGS-profile verification are essential before installation.
