The AEROQUIP Oil Seal 1.625x2.504x0.500 LGS NBR is designed for industrial rotary shaft applications requiring dependable lubricant retention and protection of bearings and internal rotating components.

Installed between a rotating shaft and stationary housing, the seal 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 can vary between manufacturers and production series, the exact sealing-lip geometry, outside-case construction, reinforcing components, 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, wear, and abrasion 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: 1.625 inches or 41.28 mm

Housing diameter: 2.504 inches or 63.60 mm

Seal width: 0.500 inch or 12.70 mm

The specific housing diameter and half-inch width suggest that this seal may be intended for a dedicated bearing housing, gearbox, pump, transmission, or OEM industrial machine. Accurate dimensional measurement and LGS profile verification are essential before installation.

Suitable replacement for compatible:

• AEROQUIP LGS Rotary Shaft Seal
• 1.625x2.504x0.500 Oil Seal
• 41.28x63.60x12.70 Rotary Seal
• Inch-Size NBR Oil Seal
