The PBR Oil Seal 1.500x2.375x0.375 LGSP NBR is designed for rotary shaft applications requiring lubricant retention around a 1.500-inch shaft within a 2.375-inch 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 and support protection of bearings, gears, pumps, motors, and other rotating components.

The product is identified by the PBR manufacturer designation LGSP. 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 PBR seal, technical drawing, or equipment specification before replacement.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing material 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 sustained elevated-temperature operation.

The inch dimensions convert approximately to:

Shaft diameter: 1.500 inches / 38.10 mm

Housing diameter: 2.375 inches / 60.33 mm

Seal width: 0.375 inch / 9.53 mm

The 1.500 × 2.375 × 0.375-inch configuration is a practical industrial size for bearing housings, gearboxes, pumps, and general rotating equipment. Replacement selection should still be based on the full LGSP cross-section, not dimensions alone.

📊 Specifications

Brand: PBR

Model / Profile: LGSP

Size: 1.500 × 2.375 × 0.375 inch

Metric Equivalent: Approximately 38.10 × 60.33 × 9.53 mm

Type: Industrial Rotary Shaft Oil Seal

Material: NBR (Nitrile Butadiene Rubber)

Profile: LGSP

Construction: Manufacturer-Specific PBR LGSP Rotary Shaft-Seal Construction

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

Dust Lip: Verify from the actual LGSP cross-section

Spring Type: Verify from the actual LGSP seal construction

Shaft Diameter (ID): 1.500 inches / 38.10 mm

Housing Diameter (OD): 2.375 inches / approximately 60.33 mm

Width: 0.375 inch / approximately 9.53 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, speed, and operating conditions

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

Installation Consideration: Verify installation depth, housing condition, shaft finish and hardness, lip orientation, concentricity, runout, and the complete LGSP cross-section before installation

Application Class: General Industrial Bearing, Gearbox, Pump, Motor, and Transmission Equipment

Standard: Inch-Size Specialized Industrial Seal

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• PBR LGSP NBR Rotary Shaft Seal
• PBR 1.500x2.375x0.375 Oil Seal
• 38.10x60.33x9.53 Rotary Seal
• 1.500-Inch Shaft Oil Seal
• Inch-Size NBR Rotary Shaft Seal
• Industrial Bearing Housing Seal
• Industrial Gearbox Shaft Seal
• Industrial Pump Shaft Seal
• OEM LGSP Profile Oil Seal
• Industrial NBR Shaft Seal

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

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