The REPCO Oil Seal 2.000x2.875x0.500 LGS NBR is designed for industrial rotary shaft applications requiring reliable lubricant retention around a 2-inch shaft.

Installed between the 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 REPCO manufacturer designation LGS. Because industrial seal-profile codes are manufacturer-specific, 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 suitable for compatible applications involving:

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

NBR offers 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: 2.000 inches or 50.80 mm

Housing diameter: 2.875 inches or 73.03 mm

Seal width: 0.500 inch or 12.70 mm

The 2.000 × 2.875 × 0.500-inch dimensions make this seal suitable for 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.

🔁 Equivalent

Suitable replacement for compatible:

• REPCO LGS Rotary Shaft Seal
• 2.000x2.875x0.500 Oil Seal
• 50.80x73.03x12.70 Rotary Seal
• 2-Inch Shaft Oil Seal
