SKF deep groove ball bearing MTRX Solid Oil 61803/6803 2RS | 17 x 26 x 5 mm
The new standard in storage technology for your bike.
What would a ride through the terrain be without mud, mud and water? Almost a wellness tour for the ball bearings built into the bike. Depending on the route, heavy loads act on the components. Damper shocks from stone and root passages and long-lasting rocking steps put a considerable strain on the bearing .
Even more critical is the permanent bombardment with dirt and the subsequent cleaning, which is often done with the high-pressure cleaner and is therefore anything but gentle on your bearings.
With MTRX you rely on driving pleasure instead of changing bearings. But driving fun also includes a lot of mud, mud and dirt. If only your beloved mountain bike would not suffer as much - especially the bearings, which can quickly refuse to work if water and dirt get inside due to the capillary action.
By transferring "Solid Oil" technology from the most demanding industrial applications to the MTB sector, SKF now has a powerful solution for bikes: MTRX. The "solid oil" of these bearings shields the individual bearing components like a protective shield against external influences.
Bearing changes are annoying. MTRX bearings were developed by engineers who are bikers themselves - just like you.
The bearings have been specially optimized and tested for use in mountain bikes. Unlike conventional bearings, they do not use grease lubrication, but an oil-soaked polymer matrix.
At SKF, this technology is known as "Solid Oil". This technology makes them particularly suitable for places in your bike that are exposed to heavy soiling.
The polymer material is pressed into the free space of the bearing. This leaves a very small gap between the polymer and the rolling elements or the raceways, which allows the bearing parts to circulate freely. The polymer material has a sponge-like structure with millions of microscopic pores, which retain the lubricating oil due to the surface tension. In operation, the polymer matrix releases the lubricating oil into the small gap and thus ensures effective lubrication.
A bearing filled with solid oil contains two to four times the amount of oil than a normal bearing filled with grease. Due to their lifetime lubrication, they cannot and do not need to be relubricated. Solid Oil cannot be washed out and practically fills up all of the free space in the bearing, minimizing the amount of dirt and contaminants that can enter the bearing. In addition, the polymer matrix supports the integrated seals from the inside (e.g. during high-pressure cleaning) and thus additionally improves the sealing effect.
Maximize your time on the bike and experience limitless bike fun with MTRX. True to the motto: Don´t worry. Just bike.

Note: When pressing in ball bearings, always make sure that the bearing is always pressed in via the outer ring, which is also the seat of the bearing.
Example hub: The hub body bearings are pressed in there via the outer ring. The bearing may therefore only be pressed in via the outer ring. Never over the inner ring.
