The TAURUS Oil Seal 145x165x13 TG NBR is designed for rotary shaft applications requiring lubricant retention around a 145 mm shaft within a 165 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, and other internal rotating components.

The product is identified by the TAURUS manufacturer designation TG. 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 TAURUS 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 service. 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: 145 mm / approximately 5.709 in

Housing diameter: 165 mm / approximately 6.496 in

Seal width: 13 mm / approximately 0.512 in

Because this is a relatively large-diameter shaft seal with a comparatively narrow radial section, shaft finish, shaft hardness, alignment, concentricity, runout, housing condition, and installation accuracy are particularly important.

📊 Specifications

Brand: TAURUS

Model / Profile: TG

Size: 145 × 165 × 13 mm

Inch Equivalent: Approximately 5.709 × 6.496 × 0.512 in

Type: Large Industrial Rotary Shaft Oil Seal

Material: NBR (Nitrile Butadiene Rubber)

Profile: TG

Construction: Manufacturer-Specific TAURUS TG Rotary Shaft-Seal Construction

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

Dust Lip: Verify from the actual TG cross-section

Spring Type: Verify from the actual TG seal construction

Shaft Diameter (ID): 145 mm

Housing Diameter (OD): 165 mm

Width: 13 mm

Pressure Capability: Primarily 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: Because of the large 145 mm shaft diameter, carefully verify shaft surface finish and hardness, housing-bore condition, installation depth, lip orientation, concentricity, and runout

Application Class: Large Industrial Bearing, Gearbox, and Rotating Equipment

Standard: Metric Specialized Industrial Seal

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• TAURUS TG NBR Rotary Shaft Seal
• TAURUS 145x165x13 Oil Seal
• 145 mm Shaft Oil Seal
• 145x165x13 NBR Oil Seal
• Large Metric Rotary Shaft Seal
• Industrial Bearing Housing Seal
• Industrial Gearbox Shaft Seal
• Industrial Pump Shaft Seal
• OEM TG Profile Oil Seal
• Industrial NBR Shaft Seal

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

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