The AEROQUIP Oil Seal 1.625x2.379x0.375 TCN NBR is intended for industrial rotary shaft applications requiring dependable lubricant retention around a 1.625-inch shaft.

Installed between a 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, gears, pumps, transmissions, and other internal components from dust, moisture, and contaminants.

The product is identified by the AEROQUIP manufacturer designation TCN. This is a manufacturer-specific profile code. The exact sealing-lip geometry, number of lips, dust-exclusion arrangement, outside-case construction, internal reinforcement, spring configuration, lip orientation, and installation direction should be verified against the original seal, technical drawing, or equipment specification before replacement.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing element is generally suitable for:

• 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 verified before use with aggressive chemicals, fuels, high continuous temperatures, ozone-rich environments, or specialized synthetic lubricants.

The inch dimensions convert approximately to:

Shaft diameter: 1.625 inches or 41.28 mm

Housing diameter: 2.379 inches or approximately 60.43 mm

Seal width: 0.375 inch or 9.53 mm

The 1.625 × 2.379 × 0.375-inch configuration is suitable for compact bearing housings, industrial gearboxes, pumps, transmissions, conveyor drives, and legacy machinery using an inch-size shaft-sealing arrangement.

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• AEROQUIP TCN NBR Rotary Shaft Seal
• AEROQUIP 1.625x2.379x0.375 Oil Seal
• 41.28x60.43x9.53 Rotary Seal
• 1.625-Inch Shaft Oil Seal
• Inch-Size NBR Rotary Shaft Seal
• Compact Bearing Housing Seal
• Industrial Gearbox Shaft Seal
• Industrial Pump Shaft Seal
• OEM TCN Profile Oil Seal
