    HIWIN crossed roller bearings

    HIWIN GmbH has specialized in developing, manufacturing and distributing linear technology for more than 25 years. Besides linear guideways, its product portfolio also includes ballscrews, linear actuators and ball bearings, not to mention complete positioning systems that incorporate linear motor axes, linear modules, planar motors, torque motors, position measurement systems, rotary tables and industrial robots. HIWIN manufactures both standard solutions and special customer-specific designs, and its service team offers consulting and product training, in addition to a maintenance and repair service. Among the company's customers are individual users and OEMs from numerous and varied branches of industry, such as machine tool manufacturers and businesses that manufacture packaging machinery, specialist machinery and medical technology. The HIWIN exhibits at EMO Hannover 2019 include a solution for engineers who repeatedly come up against the same challenge when developing robots, rotary tables, machine tools and many other automation systems - how to integrate precise and rigid bearings into an incredibly tight space.

    According to HIWIN, this is one challenge that nobody need fear now - thanks to the crossed roller bearings of the CRB range. The crosswise arrangement of the rollers at an angle of 90 degrees means the bearings can accommodate axial forces from both directions, radial forces, overturning torque loads and any combination of these. The secret to their high load-bearing capacity becomes clear on looking inside the bearings. Thanks to their special geometry, the spacers between the rollers need very little room, which means more rolling elements can be incorporated into the bearing than is the case with similar models. The special shape of the spacers also minimizes the points of contact with the rollers, thereby reducing friction losses to a minimum. The end result is a clear advantage over angular contact ball bearings and designs that use two bearing points - the HIWIN crossed roller bearings are much more compact and can therefore be used in the tightest of installation spaces. What's more, the HIWIN crossed roller bearings score highly when it comes to rigidity, too. According to the manufacturer, the linear contact of the rolling elements makes the bearings three times more rigid than conventional ball bearings. The company offers five different designs of crossed roller bearing, two preload classes and three accuracy classes and supplies the bearings with or without optional sealing. In short, it has the right variant for pretty much any application.
