The CFW Oil Seal 38x66x12 TCN NBR is designed for industrial rotary shaft applications requiring lubricant retention around a 38 mm shaft within a 66 mm housing bore.

Installed between the rotating shaft and stationary housing, the sealing element maintains controlled contact with the shaft surface to help reduce leakage of compatible oil or grease while supporting protection of bearings, gears, pumps, transmissions, and other internal rotating components.

The product is identified by the CFW manufacturer designation TCN. This is a manufacturer-specific profile code and should not automatically be treated as equivalent to a standard TC profile. 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 CFW 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 generally 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, certain fuels, specialized synthetic lubricants, ozone-rich environments, or continuous elevated-temperature operation.

The dimensions are:

Shaft diameter: 38 mm / approximately 1.496 in

Housing diameter: 66 mm / approximately 2.598 in

Seal width: 12 mm / approximately 0.472 in

The 38 × 66 × 12 mm configuration is suitable for compact-to-medium bearing housings, gearboxes, pumps, motors, transmissions, and machinery using a metric rotary shaft-sealing arrangement.

📊 Specifications

Brand: CFW

Model / Profile: TCN

Size: 38 × 66 × 12 mm

Inch Equivalent: Approximately 1.496 × 2.598 × 0.472 in

Type: Industrial Rotary Shaft Oil Seal

Material: NBR (Nitrile Butadiene Rubber)

Profile: TCN

Construction: Manufacturer-Specific CFW TCN Rotary Shaft-Seal Construction

Lip Design: TCN profile; verify exact sealing-lip geometry, number of lips, and orientation against the original seal or technical drawing

Dust Lip: Verify from the actual TCN cross-section

Spring Type: Verify from the actual TCN seal construction

Shaft Diameter (ID): 38 mm

Housing Diameter (OD): 66 mm

Width: 12 mm

Pressure Capability: Low-pressure rotary shaft-sealing service unless otherwise specified

Lubrication: Compatible oil and grease

Temperature Range: Typically approximately -30°C to +100°C for standard NBR; verify the actual compound, lubricant, shaft speed, and operating conditions

Speed Consideration: Permissible speed depends on shaft diameter, shaft finish, lubrication, temperature, alignment, concentricity, runout, lip loading, and actual NBR compound

Installation Consideration: Confirm shaft finish, housing-bore condition, installation depth, lip orientation, concentricity, runout, and protection from sharp shaft edges before fitting

Application Class: Compact-to-Medium Industrial Bearing and Rotating Equipment

Standard: Metric Specialized Industrial Seal

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• CFW TCN NBR Rotary Shaft Seal
• CFW 38x66x12 Oil Seal
• 38 mm Shaft Oil Seal
• 38x66x12 NBR Oil Seal
• Metric 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, concentricity, runout, pressure, and operating conditions before ordering.)
