In the construction of bicycle wheelsets, the flower drum is a key component that directly affects the riding experience and safety. Bearing flower drum (Peilin flower drum) and ball bearing flower drum are two common types of flower drums, each with unique performance and applicable scenarios. Today, I will provide a detailed description of the performance of these two types of flower drums to help riders make choices based on their own needs.
Bearing Flower Drum (Peilin Flower Drum)
Bearing drum, also known as Peilin drum, is famous for its deep groove ball bearing design. This type of flower drum is composed of inner and outer bearings, caps, gaskets, etc., and the main body is the flower drum. Smooth operation and excellent sliding performance, especially suitable for scenarios that require high lateral force, such as road vehicles and urban recreational vehicles. The characteristic of Peilin Flower Drum is to provide stable support and rotational performance. Due to the internal installation of a cage to maintain the distance between each ball, and the presence of sealing rings on both sides, its stability and durability are ensured. This makes the Peilin Flower Drum perform well during long-term cycling or daily cycling, and less prone to malfunctions. In addition, the maintenance of Peilin Flower Drum is relatively simple because the internal structure is clearer, making it easier to identify the problem during maintenance. The Peilin Flower Drum may not be as smooth as the Ball Flower Drum when turning. Due to the fact that the internal force of the bearing is always in a straight line, a certain resistance may be felt when the wheel tilts. But this does not affect its widespread application in scenarios such as road vehicles that require high stability and durability.
Ball shaped flower drum
Ball drum is known for its unique angular contact bearing design and tightly arranged ball bearings. This type of flower drum is composed of a ball bowl, a shaft, and tightly arranged balls. Since there is no need for a cage between the balls, it can accommodate more balls, and the contact area of each ball is also larger, which can withstand greater pressure. Ball roller drum performs well in scenarios that require high pressure and flexible rotation, such as mountain bikes that need to withstand bumps and impacts. The angular contact bearing design of the ball makes it smoother under lateral force and smoother when turning. The structure of ball bearings is relatively simple, and the material of the steel balls is relatively hard, so the ball drum has strong durability and is not prone to failure. The maintenance of ball flower drum is relatively simple, only requiring regular cleaning and lubrication. If abnormal noise or unsmooth rotation is found in the ball drum, it is recommended to check and repair it in a timely manner. The lifespan of the ball flower drum is longer, so it can save riders more maintenance costs.
Overall, both the bearing flower drum (Peilin flower drum) and the ball bearing flower drum have their own advantages. Peilin Flower Drum is suitable for scenarios that require high stability and durability due to its stable support and rotation performance, simple structure, and easy maintenance. The ball roller drum, with its smooth rotation, ability to withstand high pressure, and strong durability, is suitable for scenarios that require flexible rotation and impact resistance, such as mountain bikes.
The choice of flower drum depends on the specific needs and preferences of the rider. If you value stability and high-speed performance more, the Peilin Flower Drum may be a better choice. If you are pursuing flexibility and comfort, a ball flower drum may be more suitable for you. No matter which type of flower drum you choose, it will add fun and security to your cycling journey.
