Specna Arms Aether 8mm J-Cage bearings are significantly more durable and perform better than many other bearings on the market. Specna Arms Aether™ J-Cage bearings contain 4 ball bearings to maximize performance and 2 plain bearings to maximize bearing durability. The finesse of J-Cage bearings can be found in the ball bearings and especially in its balls, the balls are "encased" together, which better ensures that they stay in place.
HEP! The bearing installer must pay attention to the correct placement of the plain bearings. The plain bearings are designed to go on the spur gear, i.e. the middle gear, which is subjected to the most stress.
Features:
- 4x J-Cage ball bearings and 2x plain bearings (for the middle sprocket)
- "enclosed" ball bearing balls hold them in place better
