The AEROQUIP Oil Seal 0.250x0.753x0.250 LGS NBR is designed for compact rotary shaft applications requiring lubricant retention around a 0.250-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 small bearings, gears, pump components, and precision mechanisms from dust, moisture, and external contamination.

The product is identified by the AEROQUIP manufacturer designation LGS. This is a manufacturer-specific profile code. The exact sealing-lip geometry, number of lips, exclusion feature, outside-case construction, internal reinforcement, spring arrangement, 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
• Light 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: 0.250 inch or 6.35 mm

Housing diameter: 0.753 inch or approximately 19.13 mm

Seal width: 0.250 inch or 6.35 mm

The 0.250 × 0.753 × 0.250-inch configuration is suitable for miniature bearing housings, small pumps, compact gear mechanisms, instrumentation, actuators, and specialized machinery using an inch-size shaft-sealing arrangement.

Because of its small shaft diameter, reliable performance depends strongly on accurate shaft finish, concentricity, runout control, careful installation, and correct lip orientation.

📊 Specifications

Brand: AEROQUIP

Model / Profile: LGS

Size: 0.250 × 0.753 × 0.250 inch

Metric Equivalent: Approximately 6.35 × 19.13 × 6.35 mm

Type: Miniature Industrial Rotary Shaft Oil Seal

Material: NBR (Nitrile Butadiene Rubber)

Profile: LGS

Construction: Manufacturer-Specific AEROQUIP LGS Rotary Shaft-Seal Construction

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

Dust Lip: Verify from the actual LGS cross-section

Spring Type: Verify from the actual seal construction

Shaft Diameter (ID): 0.250 inch / 6.35 mm

Housing Diameter (OD): 0.753 inch / approximately 19.13 mm

Width: 0.250 inch / 6.35 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, runout, and NBR compound

Installation Consideration: The small dimensions require accurate housing alignment, controlled installation force, and protection of the sealing lip from sharp shaft edges

Application Class: Miniature and Precision Industrial Rotating Equipment

Standard: Inch-Size Specialized Industrial Seal

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• AEROQUIP LGS NBR Rotary Shaft Seal
• AEROQUIP 0.250x0.753x0.250 Oil Seal
• 6.35x19.13x6.35 Rotary Seal
• 0.250-Inch Shaft Oil Seal
• Miniature Inch-Size NBR Seal
• Small Bearing Housing Seal
• Precision Instrument Shaft Seal
• Compact Pump Shaft Seal
• OEM LGS Profile Oil Seal
• Miniature Industrial Rotary Seal

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

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