About

Seagull has developed a strong technology base for innovative air bearing spindle systems. Designed specifically to address critical industry objectives, rather than applying the "one size fits all" mentality, we strive to apply strong core capability strengths to best tailor our product response. This results in highly functional products with key features designed in, not added on. Product versatility is achieved by adopting the "cartridge bearing" approach where the customer mounting flange can be of any configuration and set in any location needed. The highly efficient air pass through for clamp handles both vacuum and pressure. Multiple clamp interfaces are available to support legacy clamps as well as our latest ultra low inertia products. Seagull spindles are fully compatible with legacy Seagull and MCS controllers as well as the latest Trust Automation linear controller. Seagull proprietary encoders are solid performers well past 30k rpm.


Seagull, as it exists today, was founded on it's development and Patent filing for the Hard Disk Drive's first "capless" and fully automated disk clamp. The "Bladder Clamp" supported 14" (355.6mm) though 2.56" (65mm) product in all aspects of production for years. It's 360 degree even gripping power captured an industry and lead Seagull into the servicing and production of many disk related products. Today, that spirit lives on in several proven and industry accepted forms. The latest is a 360 degree grip clamp that can be either vacuum or pressure activated, has disk sensing capabilities and can grip any disk at very high acceleration rates. Additionally this clamp features a check valve feature that allows pressure to unclamp the disk but flows vacuum through the clamp under use for particle capture and cleanliness. This feature can now be applied to most Seagull clamp designs. It is doubtful that any hard disk drive is manufactured today that has not touched a Seagull Clamp at some point in its processing.
