The DPH Oil Seal 110x130x12 AW/BS NBR is designed for industrial rotary shaft applications requiring dependable lubricant retention around a 110 mm shaft.

Installed between the rotating shaft and stationary housing, the sealing element creates controlled radial contact with the shaft surface. This helps reduce leakage of oil or compatible grease while limiting the entry of dust, dirt, moisture, and abrasive particles into the bearing, gearbox, pump, transmission, or drive assembly.

The product is identified by the DPH manufacturer designation AW/BS. Because industrial seal profile codes are manufacturer-specific, the exact sealing-lip geometry, number of lips, outside-diameter construction, reinforcing components, spring arrangement, dust-exclusion feature, and installation direction should be compared with the original seal or technical drawing before replacement.

The relatively small difference between the shaft and housing diameters creates a compact radial section. This configuration may be intended for a dedicated bearing housing, gearbox, transmission, pump, or OEM machine where radial installation space is limited.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing element is generally compatible with:

• Mineral oils
• Gear oils
• Hydraulic oils
• Bearing grease
• Petroleum-based lubricants
• General industrial lubricating fluids

NBR provides good resistance to petroleum-based oils, grease, wear, and abrasion under standard industrial operating conditions. Compatibility should be confirmed before use with aggressive chemicals, high continuous temperatures, ozone-rich environments, or specialized synthetic lubricants.

The metric dimensions are:

Shaft diameter: 110 mm

Housing diameter: 130 mm

Seal width: 12 mm

The 110 × 130 × 12 mm dimensions make this seal suitable for large bearing housings, gearboxes, pumps, transmissions, and OEM machinery using a compact metric rotary shaft-sealing arrangement. Accurate dimensional measurement and AW/BS profile verification are essential before installation.
