Roller bearing

Roller bearings for Dobson telescopes from 8" to 16" aperture:

• Diameter: 320 mm
• Central bore: 12 mm

The rollers run smoothly between two steel plates. The running resistance can be adjusted by adjusting the contact pressure (locking the upper and lower plates of the rocker box). The result is smooth adjustment. The "slip stick effect" is no longer present, and even at high magnifications, smooth tracking is possible.
