The AEROQUIP Oil Seal 2.750x3.504x0.500 LGS NBR is designed for industrial rotary shaft applications requiring dependable lubricant retention around a 2.750-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 compatible oil or grease while protecting bearings, gearboxes, pumps, transmissions, and other internal rotating components from contamination.

The product is identified by the AEROQUIP manufacturer designation LGS. Because industrial seal-profile codes may differ between manufacturers and production series, the exact sealing-lip geometry, number of lips, outside-diameter 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, fuels, high continuous temperatures, ozone-rich environments, or specialized synthetic lubricants.

The inch dimensions correspond approximately to:

Shaft diameter: 2.750 inches or 69.85 mm

Housing diameter: 3.504 inches or 89.00 mm

Seal width: 0.500 inch or 12.70 mm

The 2.750 × 3.504 × 0.500 inch dimensions make this seal suitable for medium-size bearing housings, industrial gearboxes, pumps, transmissions, conveyor drives, and OEM rotating machinery using an inch-size sealing arrangement. Accurate dimensional measurement and LGS-profile verification are essential before installation.

🔁 Equivalent

Suitable replacement for compatible:

• AEROQUIP LGS Rotary Shaft Seal
• AEROQUIP 2.750x3.504x0.500 Oil Seal
• 69.85x89.00x12.70 Rotary Seal
• 2.750-Inch Shaft Oil Seal
• Inch-Size NBR Rotary Shaft Seal
• Industrial Bearing Housing Seal
• Industrial Gearbox Shaft Seal
• Pump Shaft Oil Seal
• OEM LGS Shaft Seal
• General Industrial Rotary Seal

The same dimensions alone do not guarantee interchangeability. The replacement must match the original LGS cross-section, sealing-lip geometry, lip orientation, outside construction, reinforcement arrangement, spring configuration, installation direction, and material compound.

(Always verify dimensions, LGS-profile geometry, lip direction, shaft finish, housing condition, installation depth, lubricant compatibility, rotational speed, temperature, pressure, and operating conditions before ordering.)
