SKF has created a spread of excessive precision bearings primarily based on confirmed bearings expertise particularly appropriate to be used in pushed software functions.
The corporate has tailored an present, confirmed super-precision angular contact ball bearings design so it may well meet the precise necessities of the pushed software software.
“This bearing design improves robustness within the pushed software software thereby contributing to elevated effectivity and uptime,” says Karl-Heinz Littwin, Machine Device Gross sales Supervisor for Germany at SKF. “In these functions, even the smallest impacts could cause vital disruption.”
Whereas a normal chopping software is held stationary towards a rotating workpiece, a pushed software could be rotated at excessive pace. This enables it to carry out excessive precision milling, drilling and tapping operations. Naturally, this requires extremely correct bearings that usually should stand up to appreciable masses.
Pushed tools are extensively used as they’ll increase machining effectivity by performing a number of operations without delay. Nonetheless, such high-precision operations include a number of challenges. Machining house is usually restricted, with quick cycle occasions and excessive machining forces. Contaminants, noise and vibration improve the stress on equipment and on operators. These situations require bearings that may keep efficiency and keep away from downtime.
SKF’s new vary of bearings for pushed tools can be found in sealed and open variations. They provide excessive axial and radial load-carrying capability, excessive stiffness, and low noise and vibration. These options ship a number of advantages, together with low warmth technology, plus elevated reliability and productiveness.
An optimised inner geometry permits the bearings to accommodate excessive radial and axial masses. Their shut osculation gives excessive stiffness and most load-carrying capability.
“This can be a mature market software the place dependable, constant efficiency is required with the intention to keep away from expensive downtime,” says Littwin. “On this software, the proper steadiness of worth and efficiency is vital; we see our new bearings as providing prospects appreciable benefits on this specialised part of the machine software business the place complete value of possession is a key consideration.”
