The REPCO Oil Seal 1.875x2.879x0.375 LGSP NBR is designed for industrial rotary shaft applications requiring dependable lubricant retention around an inch-size shaft assembly.

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 contaminants into the bearing, gearbox, pump, or transmission assembly.

The product is identified by the REPCO manufacturer designation LGSP. Because industrial seal profile codes are manufacturer-specific, the exact sealing-lip geometry, outside-diameter 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 oil resistance, flexibility, and resistance to 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: 1.875 inches or 47.63 mm

Housing diameter: 2.879 inches or 73.13 mm

Seal width: 0.375 inch or 9.53 mm

The specific housing diameter suggests that this seal may be intended for a dedicated bearing housing, gearbox, pump, transmission, axle assembly, or OEM industrial machine. Accurate dimensional measurement and LGSP profile verification are essential before installation.
