Roller bearing for Dobsonian telescopes - 320mm diameter
For self-construction and rebuilding of Dobsonian telescopes.

The rollers run evenly between two steel plates. By adjusting the contact pressure (countering the upper and lower plate of the rocker box), the running resistance can be adjusted. The result is an even adjustment. The "slip stick effect" is no longer present, even at high magnifications jerk-free tracking is possible.
Diameter:320 mm
Central bore:12 mm
Roller bearing
Two steel plates as running surface

"Die Leichtgägngikeit des Lgers ist der Knaller. Hier muss man die Bremese einwerfen, sonst kann man nicht mal das Okular wechseln. Ich arbeite noch dran. "
