 | What is the C-Flex Pivot Bearing?
It's a flexure-based bearing utilizing internal flat crossed springs, capsuled in a cylindrical housing, to provide precise rotation with low hysteresis and no frictional losses. The C-Flex bearing will offer infinite life when used within its rated load and rotation values. Applications include Medical, Industrial, Aerospace, Semiconductor, and Optical.
Advantages include: Frictionless, Backlash-free, Self-centering, Simple installation, Low hysteresis, Vacuum applications, Stock items, No lubrication, No maintenance, and Infinite life.

 | Increase the lifespan of your bearings!
Smalley's Single-Turn Wave Springs are ideal for bearing preloads. The constant pressure they apply eliminates play between the ball bearings and the bearings' inner and outer races. Preloading can also lengthen the life of your bearings by reducing damage due to vibration. Additionally, preloading with a Single-Turn Wave Spring can minimize bearing noise!

 | Maximize moisture mitigation: Precision-fit desiccants are functional parts too
Injection molding techniques enable desiccants to provide moisture adsorption in nearly any enclosed volume, regardless of the volume's shape complexity, and are tough enough for use as structural components. Specifically, injection molding allows for desiccants formed to occupy up to 100% of available space in order to maximize moisture adsorption -- especially in enclosures for sensitive instruments -- while bringing the low costs, repeatability, and precision tolerances typical of molded plastics. Great for electronics, aerospace and defense, and more.

 | Best high-speed rotary bearing in THK history
THK has developed its best-performing, high-speed rotary bearing ever: the High-Speed, Double-Row Angular Contact Ring BWH. This rotary bearing has balls aligned inside a cage between the inner and outer rings and is part of the THK Rotary Series, along with the cross-roller ring. The main features of this product are its ability to receive loads in all directions as well as its high rigidity and rotational accuracy, which are equal to that of cross-roller rings. By adopting a new structure to change the rolling elements from rollers to balls, this product achieves the greatest high-speed performance ever offered by THK.
