Solutions for e-bikes and bicycles

In terms of energy consumption, there is no more efficient means of transportation than the bicycle. It is sporty, environmentally friendly and very flexible. The electric bike shows its strengths on steep hills or long distances. Thanks to the electric drive and the battery, less effort, longer ranges and higher speeds are possible.

Regardless of the type of drive, the right ball bearings make all the difference. Depending on the bearing location, for example, energy efficiency, power density or service life are in demand. Your requirements are in good hands with us. Rely on our many years of experience in bicycle applications.

Typical applications

Wheel bearings

Significant energy can be saved at this bearing point on your bikes! On the one hand, the sealing friction should be kept as small as possible. On the other hand, the ball bearing must have a seal that reliably protects against splash water and dust.

Our bearings with solid lubricant offer you even more protection. The goal is the longest possible service life and low maintenance requirements with maximum energy efficiency. We will find the optimal solution for you!

Bottom bracket bearings

Noise is absolutely taboo here. Maximum energy efficiency is also a prerequisite. In addition, high loads and torques must be absorbed. Once again, maximum service life and long maintenance intervals are crucial.

In the development of bottom brackets, we have partnered with several well-known manufacturers of electric and traditional bicycles for many years. Take advantage of our first-class expertise, so you can fully concentrate on your future topics such as sensor technology or software.

Electric drive

In the electric motor, power density matters. Less installation space and weight means less energy demand and lower overall costs for your bike. With low-friction and quiet bearings from CW Bearing, you reduce energy requirements and noise.

Steering and chassis

Another particularly critical bearing point of the bicycle is the steering.  Here, the bearings must be free of play, robust and safe. Noise is not tolerated in either the steering or the chassis. A frequent cause is small particles that penetrate the bearing.

Which seal best protects against this? Just ask the experts at CW Bearing. Our seal kit can be combined with all ball bearing designs. And if that is not enough, we will develop a solution for you with a special seal. In this way, you extend service life and maintenance intervals to the absolute maximum.
