Weight, Space & Cost Solutions for the Hard Disk Drive Market

Saint-Gobain helps HDD designers by designing RENCOL® Tolerance Rings which improve resonance and torque ripple performance when mounting the bearing assembly or bearing cartridge.

Saving Space

Consumers purchasing hard disk drives want ever smaller and more portable packaging. Mounting a bearing assembly or bearing cartridge within a confined space presents hard disk drive manufacturers a significant challenge. In the pursuit of thinner hard drives, Saint-Gobain RENCOL® Tolerance Rings have been developed by our engineers to reduce the size of disk drives whilst delivering optimum performance. That’s why the leading manufacturers of hard disk drives turn to Saint-Gobain.

Cutting Costs

Reducing manufacturing costs and ultimately, costs for the end user in the hugely competitive global hard disk drive market is crucial. Our engineers understand the price pressures which hard disk drive manufacturers face.

Our tolerance rings accelerate hard disk drive assembly lines to maximise yield and reduce the overall cost of assembly in each and every unit.
