Almost all the joints of the machinery present a com- plicated system of sliding parts moving over small but beauti- fully curved friction bearings
. And while upon this matter of detail, it is remarkable that the long leverages of their machines are in most cases actuated by a sort of sham musculature of the disks in an elastic sheath; these disks become polarised and drawn closely and powerfully together when traversed by a current of electricity.

The SR60 Torus uses a direct-drive continuous rotation brushless motor with low friction bearing
, and the system requires no gears or clutches.
Why you should care: The 300L uses a unique slide way design and a low friction bearing
surface, which combines one box way for high rigidity with one vee way for high accuracy on both axes.
This type of journal box was known as a friction bearing
. All newer railroad cars have roller bearings.
* GARDOBOND[R] for surface pre-treatment processes providing corrosion protection, enhanced paint adhesion or surface lubrication for friction bearing
They can be integrated with an online hydraulic/pneumatic or electric actuator for automatic operation, or can be manually operated with a large, low friction bearing
