Non-standard customization

When standard products cannot meet your unique challenges, ROKB’s non-standard customization service is your perfect answer. We focus on designing, engineering, and manufacturing customized bearing solutions to provide core support for your innovative equipment and demanding applications.

1. Our customized scenario for you

When you face the following challenges, it is the beginning of our cooperation:

Space limitations: The installation location is unconventional and requires special dimensions or structures. Extreme working conditions: facing tests of ultra-high temperature, ultra-low temperature, strong corrosion, high vacuum or extreme heavy load. Performance improvement: We hope to break through the performance bottleneck of existing devices, such as pursuing higher speeds, lower noise, or longer lifespan. System integration: Bearings need to be integrated with sensors, seals, lubrication, or other functional components. Material innovation: It is necessary to deal with special media or environments that cannot be met by standard materials.

2. Our customization capability and scope

ROKB has full chain customization capabilities from design to manufacturing, flexibly responding to your needs.

Size customization: Beyond the standard catalog, we provide bearing manufacturing for any non-standard inner diameter, outer diameter, and width dimensions. Structural customization: Innovative cage development using polymer materials, special brass or bronze cages to meet high-speed, low torque or corrosion-resistant requirements. Roller/raceway optimization: Customize logarithmic generatrix rollers, non-standard spheres, or optimize raceway curves to improve stress distribution and reduce noise. Customized guidance and sealing: Design special guidance methods (such as roller guidance, ring guidance) and customized sealing systems (contact, non-contact, labyrinth) to cope with complex polluted environments. Material customization: special steel applications, high-temperature bearing steel, stainless steel, nitriding stainless steel, etc. Ceramic applications, providing full ceramic (zirconia, silicon nitride) or hybrid ceramic bearings to cope with electrical, magnetic, and corrosion-resistant working conditions. Surface coating, providing surface coatings (such as zinc, chromium), DLC coatings, etc., to enhance wear resistance, corrosion resistance, or insulation performance. Clearance and preload customization: Based on your shaft system fit and thermal expansion characteristics, accurately calculate and provide the most suitable clearance level or preload setting. Technology integration: Integrate lubrication holes/grooves, sensors, status monitoring units, etc. with the bearing body for integrated design.

3. The core process of non-standard customization

We ensure that every customized project achieves its goals accurately and efficiently through rigorous processes.

Deep integration of requirements: Our application engineers will communicate closely with you to gain a deep understanding of your application scenario, performance goals, and all boundary conditions. Scheme design and simulation: The engineering team conducts structural design, material selection, and life calculation. Utilize tools such as finite element analysis and dynamic simulation to virtually verify the reliability of the scheme before manufacturing. Scheme review and confirmation: We will submit a detailed technical scheme and 2D/3D drawings to you, and conduct a thorough review until you confirm and sign. Prototype sample manufacturing and testing: Prior to formal mass production, prototype samples can be provided and tested and verified in our laboratory or on your equipment. Small batch trial production and delivery: After sample validation, small batch production is carried out to ensure process stability and ultimately deliver qualified products.
