NSK says its linear guides bring “higher dynamics” to pick-and-place machines.

As machines for the semiconductor industry operate with cycle times of one second or less, pick-and-place units must offer very high dynamic performance.

A case in point can be seen at a manufacturer of chip-mounting systems, where NSK recommended a combination of its ball screw and miniature linear guide technologies to replace the existing linear motor and significantly increase dynamic capability.  Continue reading NSK miniature linear guides bring ‘higher dynamics’ to pick-and-place machines

NSK launches low-friction ball bearings which ‘increase energy efficiency’

NSK has launched low-friction ball bearings which it says increase energy efficiency and reduce operational noise in drive systems. 

Bearings of this type will also reduce heat generation, which in turn helps to extend service life, according to the company.

Based on concepts such as optimised raceway geometry and special sealing concepts, NSK has developed several series of ball bearings that offer significantly lower friction characteristics.  Continue reading NSK launches low-friction ball bearings which ‘increase energy efficiency’

NSK claims ‘10 times more service life’ for linear guides in robotic welding applications

A manufacturer of sheet metal assemblies recently sought a solution to short lifespan issues with the drive and guide elements on its automated welding systems.

In fact, the linear guides for a robotic welding gun on one particular production line had to be replaced every two or three months.

Due to the cost of replacement parts and maintenance time, as well as equipment downtime, the company asked NSK to investigate and provide a proposal to address the problem.  Continue reading NSK claims ‘10 times more service life’ for linear guides in robotic welding applications
