Press kit specifically made for bearing number 6903. The press kit 6903 (17x30x7) is made for bearings of the following dimensions:
- Bore diameter (inner diameter) : 17 mm.
- Outer diameter : 30 mm.
- Width : 7 mm.
The bearing number is engraved on each of the three parts of the press kit so it makes it easy to clearly identify all parts rapidly. The sections to use to extract and to insert your bearings are respectively identified with the "EXT" and "INS" engraving.
INS section applies pressure only on the outer race of the bearings to protect the balls and inner race of your new bearings. INS section's conical shape accommodates bearings with an extended inner ring. The "EXT" and "INS" parts can be used for F6903 bearings, which has a flange on one of its side, but note that the CUP cannot be used on flanged bearings as it will not fit.
All Momentum Cycle Bearing Press Kits are made of thermoplastic polymer. In addition to being fully recyclable, this material gives excellent properties such as:
- excellent structural and dimensional stability.
- very good mechanical resistance.
- very good chemical and impact resistance.
Chances are that you had to remove your derailleur or brake housing to proceed with the job. We are providing the first UV resistant Ty-Rap® to help you get your bike together once the job is done. All our Bearing Press Kits are available in your favorite color, as long as your favorite color is black.
The press kit 6903 (17x30x7), and all Momentum Cycle tools, are proudly developed and made in Canada. Momentum Cycle's Bearing Press Kits and the Crank are precisely manufactured using 3D print technology.
