This bearing uses air or magnetic power as lubricants. The PNEUMATIC BEARING generates an air layer in the bearing part by supplying air from the air supply source, so that it can rotate with low friction and low hysteresis. The magnetic bearing applies magnetic repulsive power to provide a gap of several μ to several tens μ to provide same effects as the PNEUMATIC BEARING.
When it is used for the roll grinder as a non-contact spacer: (It is mass production products since their diameters are fixed).

The products may not be damaged since it does not contact.
High spacing accuracy (several μ〜μ or less)
If it is used for the cylindrical grinder for finishing work, it may not be an obstacle near the whetstone processing component since it has a half circle shape, and it is not necessary to move, unlike to the ordinary products.
By arranging several units of this device crosswise etc., it can prevent vibration and bending in both directions of self-weight bending vertical direction and the processing direction.
By arranging this device at the roll center of the grinder, it is possible to make minute crown processing by applying appropriate bending.
When this device is used for the guide roll for film transfer as a non-contact spacer

The diameter of the guide roll can be minimized and then the GD2 will be small.
It has an effect to release air coming together with the transferred items.
Maintenance free
Any complicated structures such as a segment roll are not required.
