These miniature ball bearings are meticulously crafted to ensure optimal performance and reliability. With an open design, these bearings offer easy access for lubrication and maintenance, making them an essential part of motorcycle systems that demand exceptional smoothness and durability.


These miniature ball bearings find their application in various motorcycle parts, contributing to the seamless functioning of critical components. They are commonly used in motorcycle engines, transmissions, wheels, and suspension systems. Whether it's reducing friction in high-speed engine rotations or ensuring stability in wheel assemblies, these bearings play a pivotal role in enhancing the overall performance and safety of motorcycles.


  1. Precision Construction: Our miniature ball bearings are manufactured with the utmost precision, ensuring consistent performance under demanding conditions.

  2. Low Friction: These bearings are designed to minimize friction, enabling efficient power transfer and reduced energy loss, which is crucial for optimizing motorcycle performance.

  3. Durable Build: Crafted from top-quality materials, these bearings exhibit exceptional durability and can withstand the rigors of various riding environments.

  4. Open Design: The open design facilitates easy lubrication and maintenance, allowing for prolonged service life and hassle-free upkeep.

  5. Enhanced Performance: By reducing heat generation and improving rotational efficiency, these bearings contribute to the overall performance enhancement of the motorcycle.

  6. Versatile Compatibility: The bearings are engineered to fit seamlessly into a wide range of motorcycle models, making them a versatile choice for motorcycle manufacturers and enthusiasts.

  7. Quality Assurance: Our bearings undergo rigorous quality testing, ensuring they meet stringent industry standards and provide reliable performance over time.

.Customized bearing engineering and supply to our worldwide clients for more than 25years,we are professional.

.Support radial load and a certain degree of axial load , slight misalignment allowable. (consult us for more detailed information)

.Very high RPM speed, for example in dental equipment the highest 400,000rpm .

.According to the conditions which the equipments served by the bearing will face to , RPM speed , force bring to the bearing , bearing components material,tolerance grade , heat treatment method,internal play,grease,parameters of raceway…will be considered professionally and comprehensively.

.For example , normally chrome steel GCr15/SAE52100/DIN100Cr6 is used for rings , NBR,HNBR/Viton FPM/ACM for seals , steel ribbon/Nylon PA/PTFE/PEEK/Brass for the cage, chrome steel/stainless steel/Ceramic ZrO2 Si3N4 for the balls . Sometimes hybrid is designed if necessary .

.Internal play can be C2,CN,C0,C3,C4…..or special data according to engineering.

.Our bearing normally operating temperature range -30°C to +110°C . With different material/heat treatment/grease…..will be wider range , consult us for more detailed information if you need.

.For special requires , extreme high/low temperature , insulation , anti-corrsion,RPM…… consult to us.

.Each piece product from us is customized based on customer’s demand to the bearing, our action guiding goal is engineering and supply them with top quality&best price.

.We are partnership supplier to ODM/OEM/wholesaler , we are unsung heros, supporting machines running in every corner of the world.
