SKF - MTRX Bearing - 619/8

MTRX - The new standard in bearing technology. Based on decades of experience in industrial applications, SKFs MTRX solid oil bearings are the most reliable and durable solution for mountain bikings most highly contaminated and wet environments.

MTRX bearings are filled with SKF Solid Oil technology. The oil impregnated polymer matrix lubricates and protects the bearing even under the toughest operating conditions and ensures significantly longer service life even when using high-pressure cleaners. The deep groove ball bearings have been developed for bearing arrangements where high humidity, occasional contact with water or heavy contamination cause major problems.

MTRX bearings provide many advantages due to Solid Oil, especially if bearings are mounted at dirt-exposed positions in the bike. The polymer matrix contains two to four times more oil than bearings with conventional grease fill, and so protects the bearing components, leading to longer bearing life, even under extremely contaminated conditions, while requiring no relubrication.The polymer filling physically supports integral seals, reinforcing their effectiveness while the bike is undergoing high-pressure cleaning. MTRX bearings prevent lubricant washout and ingress of contaminants more reliably than grease-filled bearings.
