71903 LLB - ABEC-5 Angular-Contact Bearing (C3 Clearance) - 17 x 30 x 7mm

The ABEC-5 Angular-Contact bearing is a versatile component often used as a front hub bearing, in certain older square taper bottom brackets, and can also function as a pivot bearing. However, the MAX-type variant is more suitable for suspension applications. This precision-engineered bearing boasts Grade 10 balls within deep-groove design races and is fortified with dual-lip labyrinth (LLB) seals, specifically built to endure daily usage and environmental elements.

Crafted to maintain peak performance, this bearing is infused with 90% fill of Mobilux NGLI 2 high-pressure waterproof synthetic grease, enhancing its resilience and longevity. When correctly installed and adjusted (with the black seal facing in), Enduro Angular Contact (A/C) bearings ensure all the bearing's balls engage, distributing force across a larger surface area. This design reduces friction, minimizes wear, and substantially extends the bearing's operational life.

The Enduro line of bearings is offered in various material options such as high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless balls. These bearings are consistently engineered with the deepest groove races possible to accommodate larger balls and incorporate dual-lip seals that travel within micro-grooves, forming a complete labyrinth for superior protection against harsh environmental elements.
