The NOK Oil Seal 130x158.8x13 TC NBR is designed for rotary shaft applications requiring lubricant retention around a 130 mm shaft within a 158.8 mm housing bore.

The TC profile is commonly constructed with a primary radial sealing lip and a secondary auxiliary lip. The primary lip typically incorporates a garter spring to maintain controlled radial contact against the rotating shaft, while the auxiliary lip helps reduce ingress of dust, dirt, moisture, and external contaminants.

The seal commonly incorporates internal metal reinforcement to maintain dimensional stability and secure retention within the housing bore. Although TC is a widely recognized seal profile, the exact NOK cross-section, elastomer covering, case design, lip geometry, and installation orientation should still be checked against the original seal or technical drawing 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, certain fuels, specialized synthetic fluids, ozone-rich environments, or continuous elevated-temperature service.

The dimensions are:

Shaft diameter: 130 mm

Housing diameter: 158.8 mm

Seal width: 13 mm

The 130 × 158.8 × 13 mm configuration is suitable for large bearing housings, heavy gearboxes, pumps, transmissions, conveyor drives, and industrial machinery using a metric TC-style rotary shaft seal.

For a seal of this diameter, shaft finish, shaft hardness, housing alignment, concentricity, runout, installation depth, and proper lubrication at the sealing interface are important for reliable sealing performance and service life.

📊 Specifications

Brand: NOK

Model / Profile: TC

Size: 130 × 158.8 × 13 mm

Type: Large Double-Lip Industrial Rotary Shaft Oil Seal

Material: NBR (Nitrile Butadiene Rubber)

Profile: TC

Construction: Elastomer sealing element with internal metal reinforcement; verify exact NOK construction

Lip Design: Primary sealing lip with auxiliary secondary lip

Dust Lip: Yes, auxiliary dust/exclusion lip commonly incorporated in standard TC construction

Spring Type: Garter spring on the primary sealing lip

Shaft Diameter (ID): 130 mm

Housing Diameter (OD): 158.8 mm

Width: 13 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, surface finish, lubrication, temperature, lip loading, alignment, concentricity, runout, and NBR compound

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

Application Class: Large and Heavy-Duty Industrial Bearing and Rotating Equipment

Standard: Metric TC Rotary Shaft Seal

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• NOK TC NBR Rotary Shaft Seal
• NOK 130x158.8x13 Oil Seal
• 130 mm Shaft Oil Seal
• 130x158.8x13 NBR Oil Seal
• Double-Lip NBR Shaft Seal
• TC Rotary Shaft Seal
• Large Bearing Housing Seal
• Heavy Gearbox Shaft Seal
• Industrial Pump Shaft Seal
• OEM TC Profile Oil Seal

The same dimensions alone do not guarantee interchangeability. The replacement must match the original TC cross-section, lip geometry, auxiliary-lip arrangement, garter-spring configuration, case construction, material compound, lip direction, installation depth, and operating requirements.

(Always verify dimensions, TC profile, lip arrangement, shaft finish, shaft hardness, housing condition, installation depth, lubricant compatibility, rotational speed, temperature, alignment, concentricity, runout, pressure, and operating conditions before ordering.)
