The FP Oil Seal 30x52x7 GP NBR is designed for industrial rotary shaft applications requiring lubricant retention around a 30 mm shaft within a 52 mm 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, pumps, motors, and other internal rotating components from external contaminants.

The product is identified by the FP manufacturer designation GP. 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 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 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 dimensions are:

Shaft diameter: 30 mm

Housing diameter: 52 mm

Seal width: 7 mm

The 30 × 52 × 7 mm size is suitable for compact bearing housings, electric motors, industrial pumps, gearboxes, transmissions, and general OEM rotating assemblies.

📊 Specifications

Brand: FP

Model / Profile: GP

Size: 30 × 52 × 7 mm

Type: Industrial Rotary Shaft Oil Seal

Material: NBR (Nitrile Butadiene Rubber)

Profile: GP

Construction: Manufacturer-Specific FP GP Rotary Shaft-Seal Construction

Lip Design: GP 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 GP cross-section

Spring Type: Verify from the actual seal construction

Shaft Diameter (ID): 30 mm

Housing Diameter (OD): 52 mm

Width: 7 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, and NBR compound

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

Application Class: General Industrial Bearing and Rotating Equipment

Standard: Metric Specialized Industrial Seal

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• FP GP NBR Rotary Shaft Seal
• FP 30x52x7 Oil Seal
• 30x52x7 NBR Oil Seal
• 30 mm Shaft Rotary Seal
• Metric NBR Shaft Seal
• Industrial Bearing Housing Seal
• Electric Motor Shaft Seal
• Industrial Gearbox Oil Seal
• Industrial Pump Shaft Seal
• OEM GP Profile Oil Seal

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

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