The TROSTEL Oil Seal 2.000x2.886x0.500 TCN NBR is designed for industrial rotary shaft applications requiring lubricant retention around a 2.000-inch shaft.

Installed between the rotating shaft and stationary housing, the sealing element maintains 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 TROSTEL 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 normal industrial operating conditions. Compatibility should be verified before use with aggressive chemicals, fuels, continuous high temperatures, ozone-rich environments, or specialized synthetic lubricants.

The inch dimensions convert approximately to:

Shaft diameter: 2.000 inches or 50.80 mm

Housing diameter: 2.886 inches or approximately 73.30 mm

Seal width: 0.500 inch or 12.70 mm

The 2.000 × 2.886 × 0.500-inch configuration is suitable for compact-to-medium 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:

• TROSTEL TCN NBR Rotary Shaft Seal
• TROSTEL 2.000x2.886x0.500 Oil Seal
• 50.80x73.30x12.70 Rotary Seal
• 2.000-Inch Shaft Oil Seal
• Inch-Size NBR Rotary Shaft Seal
• Industrial Bearing Housing Seal
• Industrial Gearbox Shaft Seal
• Industrial Pump Shaft Seal
• OEM TCN Profile Oil Seal
• Industrial NBR Shaft Seal

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

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