The OEM Oil Seal 17x28x7 TC NBR is designed for rotary shaft applications requiring reliable lubricant retention around a 17 mm shaft.

Installed between the rotating shaft and stationary housing, the primary sealing lip maintains controlled radial contact with the shaft surface. A garter spring supports the main lip and helps maintain consistent sealing pressure during operation.

The TC profile commonly uses two lips:

• A spring-loaded primary sealing lip for retaining oil or compatible grease
• An auxiliary dust lip for reducing the entry of dust, dirt, moisture, and external contaminants

The seal generally incorporates a metal reinforcement within the elastomer-covered outer diameter. This construction helps maintain dimensional stability and supports secure installation in the housing bore.

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 offers good resistance to oil, grease, abrasion, and mechanical wear under standard industrial operating conditions. Compatibility should be verified before use with aggressive chemicals, high continuous temperatures, ozone-rich environments, fuels, or specialized synthetic lubricants.

The metric dimensions are:

Shaft diameter: 17 mm

Housing diameter: 28 mm

Seal width: 7 mm

The compact 17 × 28 × 7 mm dimensions make this seal suitable for small motors, pumps, gear units, bearing assemblies, machine tools, power tools, and OEM mechanical equipment.
