Enduro Bearings MR 18307 LLU/LLB SL CN - ABEC5 - 18x30x7 Silver is a high-performance radial bearing designed specifically for demanding bicycle applications. Crafted with 52100 High-Carbon Chromium alloy races and grade 10 balls, this bearing delivers exceptional durability and smooth operation. The unique solid-lubricant polymer infused inside eliminates grease, preventing water and dirt ingress, which significantly enhances longevity and reliability.
This bearing features a dual-seal system: a robust LLU seal facing outward to block contaminants and a lighter-contact LLB seal inward to retain lubrication without excess drag. Its deep groove design accommodates larger balls, maximizing contact area for improved load capacity and extended bearing life. Ideal for use as a hub bearing or pivot bearing, it offers dependable performance in various cycling components.
Enduro Bearings are engineered with precision, using a variety of materials including High-Carbon Chromium Steel and advanced ceramic hybrids. Every bearing includes dual-lip seals with micro grooves forming a labyrinth that provides outstanding protection from the elements, ensuring smooth and consistent function even in harsh conditions.
What does ABEC-5 rating mean for this bearing?
The ABEC-5 rating indicates a high level of precision and tolerance in manufacturing, ensuring smooth and efficient rotation with minimal friction, ideal for high-performance bicycle components.
Can this bearing be used in suspension systems?
While it can be used as a pivot bearing, the MAX-type version of this bearing is better suited for suspension applications due to enhanced load and impact resistance.
