The S698 2RS radial bearing utilizes premium 440C stainless steel alloy races paired with precision Grade 10 balls. Its dual rubber seal configuration provides superior protection against environmental contaminants while effectively retaining the 90% fill of Kluber NBU52 grease—a specialized water-resistant formulation engineered for exceptional lubricity and adhesion under demanding conditions.

The ENDURO S698 2RS Stainless Radial (C3) Mini Bearing delivers reliable performance in multiple applications, functioning effectively as both a hub bearing and pivot bearing. Measuring 8 x 19 x 6mm, this precision-engineered component features stainless steel construction for durability in demanding environments. While versatile in application, cycling professionals should note that the MAX-variant of this bearing offers superior characteristics specifically optimized for suspension systems where enhanced load capacity and durability are required.

Not all stainless steel is created equal.

Enduro exclusively employs 440C stainless steel for both balls and races, ensuring exceptional longevity and corrosion protection in suboptimal conditions. This premium alloy stands out within the 440-series for its superior hardness, strength, and wear resistance—attributes derived from its elevated carbon content. The manufacturing process involves sophisticated multi-stage heat treatments and cryogenic processing to achieve optimal mechanical characteristics. While 440C exhibits approximately 20% lower load capacity and marginally reduced hardness compared to the 52100 chromium steel found in Enduro's standard bearings, it represents an ideal solution for applications exposed to moisture, frequent washing protocols, or perspiration contamination.

Enduro stainless bearings all carry a full two year anti-corrosion warranty.

The ENDURO S698 2RS Stainless Radial Mini Bearing exemplifies precision engineering within Enduro's comprehensive bearing portfolio. This 8 x 19 x 6mm component belongs to a sophisticated lineup featuring multiple material options: high-carbon chromium steel, 440C stainless steel, ceramic-hybrid configurations, and premium XD-15 with ceramic or stainless ball options. Enduro's distinctive design philosophy incorporates maximized groove depth to accommodate larger ball bearings, enhancing load capacity and durability. The dual-lip seal system operates within a precision micro-groove, creating an advanced labyrinth structure that delivers superior contamination resistance against environmental elements—critical for maintaining optimal performance in demanding cycling applications.
