Tschudin Cube 350 centreless grinder uses NSK RA highprecision roller guides
The new Tschudin Cube 350 centreless grinding machine is using NSK’s RA series of low-friction, high-rigidity roller guides, where they are helping to generate excellent levels of surface finish on machined workpieces. Tschudin’s Cube 350 operates using the centreless cylindrical grinding method and, thanks to design innovation, benefits from the potential to install several machines side-by-side. In addition to its high-precision capability, the machine facilitates very short set-up times for product changeovers, thus enabling the economic machining of small component batch sizes. The drive design has a major impact on the performance of this precision grinding machine. Deploying linear drives in three axes (X-axis/control wheel adjustment, U-axis/grinding wheel adjustment and…

NSK Agri Disc Hubs: Zuverlässige Wälzlagereinheiten für extreme Umgebungsbedingungen
Feuchtigkeit, Staub und Schmutz, korrosive Düngemittel und hohe mechanische Belastungen z.B. durch Steinschlag: Wälzlager in Maschinen der Landtechnik werden stark beansprucht. Exakt für diese Extrem-Anwendung hat NSK die Agri Disc Hubs entwickelt. Zu ihren Konstruktionsmerkmalen gehören ein robustes Lagerdesign und eine hochwirksame Abdichtung. Diese Lagereinheiten werden in Deutschland gefertigt. Führende Hersteller setzen sie in ihren Bearbeitungsgeräten wie Kurzscheibeneggen, Sämaschinen und Randstreifenmähern ein. Die wirklich ungünstigen Umgebungsbedingungen im Betrieb und die Reinigung der Maschinen mit dem Hochdruckreiniger stellen extreme Anforderungen an Wälzlager und Dichtungen von Bodenbearbeitungsgeräten in der Landwirtschaft. Ein konventionelles Lager weist keinesfalls die erforderliche Robustheit auf, um unter diesen Bedingungen die für einen zuverlässigen und produktiven Betrieb nötige Standfestigkeit…

NSK Agri Disc Hubs offer reliability in extreme conditions
For bearings deployed in the agriculture sector there is no shortage of potential hazards, including moisture, soil dust, corrosive fertilisers and very high shock loads (such as those generated by stone chipping). However, the robust bearing design and highly effective sealing of NSK Agri Disc Hubs makes them a proven choice in extreme operating conditions. Manufactured in Germany, these innovative units are a popular choice for common farming implements such as short disc harrows, seed drills and flail mowers. Extremely harsh working conditions, along with high-pressure washing routines, place a raft of demands on the bearings and seals found in equipment for the agriculture industry. A low-quality bearing will not…
