The AKRON Oil Seal 4.813x5.544x0.469 TG Silicone is designed for industrial rotary shaft applications requiring lubricant retention around a 4.813-inch shaft under a comparatively wide operating-temperature range.

Installed between a rotating shaft and stationary housing, the sealing element creates controlled radial contact with the shaft surface. This helps reduce leakage of compatible oil or grease while protecting bearings and internal components from contamination.

The product is identified by the manufacturer-specific TG Profile. Industrial profile codes can vary between brands and production series. Therefore, the exact lip geometry, number of sealing lips, dust-lip configuration, outside-case construction, internal reinforcement, spring arrangement, and installation direction should be compared with the original seal or technical drawing before replacement.

The sealing element is manufactured from Silicone Rubber (VMQ). Silicone is generally selected for applications requiring:

• High-temperature resistance
• Good low-temperature flexibility
• Resistance to ozone and weathering
• Stable elasticity across a broad temperature range
• Compatibility with selected mineral oils and greases
• Reliable sealing at moderate shaft speeds

Silicone rubber generally has lower abrasion and tear resistance than NBR or FKM. Shaft finish, alignment, lubrication, rotational speed, and installation condition are therefore especially important. Silicone seals should not be operated dry unless specifically approved for the application.

Fluid compatibility must be verified because Silicone may not be suitable for every fuel, aggressive chemical, high-pressure application, or specialized synthetic lubricant.

The inch dimensions correspond approximately to:

Shaft diameter: 4.813 inches or 122.25 mm

Housing diameter: 5.544 inches or 140.82 mm

Seal width: 0.469 inch or 11.91 mm

The large shaft diameter and relatively narrow axial width make this seal suitable for specialized bearing housings, gearboxes, process machinery, pumps, transmissions, and OEM equipment using a large inch-size shaft-sealing arrangement. Accurate dimensional measurement and TG-profile verification are essential before installation.

🔁 Equivalent

Suitable replacement for compatible:

• AKRON TG Silicone Rotary Shaft Seal
• AKRON 4.813x5.544x0.469 Oil Seal
• 122.25x140.82x11.91 Rotary Seal
• 4.813-Inch Shaft Oil Seal
• Inch-Size Silicone Oil Seal
• High-Temperature Bearing Housing Seal
• Industrial Gearbox Silicone Seal
• Pump Shaft Silicone Seal
• OEM TG Shaft Seal
