The GARLOCK Oil Seal 1.188x1.575x0.313 Model 76 NBR is intended for rotary shaft applications requiring lubricant retention around a 1.188-inch shaft within a 1.575-inch housing bore.

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 bearings, gears, pump components, and other internal rotating parts from external contamination.

The product is identified by the GARLOCK designation Model 76. This is a manufacturer-specific seal model, so the exact lip geometry, number of sealing lips, dust-exclusion feature, spring arrangement, case construction, internal reinforcement, lip orientation, and installation direction should be checked against the original seal, GARLOCK 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 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, ozone-rich environments, specialized synthetic lubricants, or continuous high-temperature service.

The inch dimensions convert approximately to:

Shaft diameter: 1.188 inches or 30.18 mm

Housing diameter: 1.575 inches or 40.01 mm

Seal width: 0.313 inch or 7.95 mm

The 1.188 × 1.575 × 0.313-inch configuration is suitable for compact bearing housings, small pumps, precision gear drives, motor assemblies, instruments, and legacy machinery using an inch-size sealing arrangement.

📊 Specifications

Brand: GARLOCK

Model / Profile: Model 76

Size: 1.188 × 1.575 × 0.313 inch

Metric Equivalent: Approximately 30.18 × 40.01 × 7.95 mm

Type: Compact Industrial Rotary Shaft Oil Seal

Material: NBR (Nitrile Butadiene Rubber)

Profile: GARLOCK Model 76

Construction: Manufacturer-Specific GARLOCK Model 76 Rotary Shaft-Seal Construction

Lip Design: Model 76 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 Model 76 cross-section

Spring Type: Verify from the actual seal construction

Shaft Diameter (ID): 1.188 inches / approximately 30.18 mm

Housing Diameter (OD): 1.575 inches / approximately 40.01 mm

Width: 0.313 inch / approximately 7.95 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, alignment, runout, lip loading, and NBR compound

Installation Consideration: Confirm shaft finish, shaft-edge condition, housing-bore condition, installation depth, lip direction, and concentricity before fitting

Application Class: Compact Industrial Bearing and Rotating Equipment

Standard: Inch-Size Specialized Industrial Seal

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• GARLOCK Model 76 NBR Shaft Seal
• GARLOCK 1.188x1.575x0.313 Oil Seal
• 30.18x40.01x7.95 Rotary Seal
• 1.188-Inch Shaft Oil Seal
• Compact Inch-Size NBR Seal
• Small Bearing Housing Seal
• Precision Gear Drive Seal
• Compact Pump Shaft Seal
• OEM Model 76 Oil Seal
• Industrial NBR Rotary Seal

The same dimensions alone do not guarantee interchangeability. The replacement must match the original Model 76 cross-section, sealing-lip geometry, lip orientation, outside-case construction, reinforcement arrangement, spring configuration, installation direction, NBR compound, and operating requirements.

(Always verify dimensions, Model 76 construction, lip direction, shaft finish, housing condition, installation depth, lubricant compatibility, rotational speed, temperature, alignment, runout, pressure, and operating conditions before ordering.)
