Essential Hub Protection Components:

These double-lip oil seals are critical for ensuring that the hub bearings on your RV or utility trailer remain properly lubricated.

They establish a reliable barrier that effectively locks grease securely inside the hub while simultaneously preventing the intrusion of moisture, road salts, and various debris into the bearings.

Double-Lip Sealing Technology:

Featuring an advanced double-lip design, these seals are equipped with two sealing edges that work in tandem. The primary sealing lip is responsible for retaining grease within the hub, while the secondary lip acts as a barrier against dust and contaminants—a design that offers superior protective performance compared to single-lip oil seals.

Premium Nitrile Rubber Compound:

Manufactured using high-quality Nitrile Rubber (NBR), a material renowned for its exceptional resistance to petroleum-based lubricants.

This material maintains excellent flexibility across a wide temperature range and effectively resists aging phenomena—such as hardening, cracking, and swelling—that can lead to seal failure.

Reinforced Steel Casing:

Each oil seal features a precision-formed internal casing made from #45 steel, ensuring structural integrity throughout the installation process.

This robust casing design not only guarantees a consistently tight fit within the hub bore but also effectively prevents seal failure caused by deformation.
