The base plates rotate on plastic pads, and that combination of sliding and weight makes the movement stiff. You push, nothing happens, you push harder and then the telescope overshoots the object.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This roller bearing fixes that for a modest amount. You place it between the base plates and the azimuth movement becomes smooth, without having to drill or glue anything.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-3 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Dobson-rollager-S-6-12-3.jpg\" alt=\"Omegon roller bearing for Dobson telescopes from 6 to 12 inches\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Dobson-rollager-S-6-12-1.jpg\" alt=\"Omegon roller bearing for Dobson telescopes from 6 to 12 inches\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Dobson-rollager-S-6-12-2.jpg\" alt=\"Omegon roller bearing for Dobson telescopes from 6 to 12 inches\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Dobson-rollager-S-6-12-.jpg\" alt=\"Omegon roller bearing for Dobson telescopes from 6 to 12 inches\" title=\"\"><\/figure><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">What changes at high magnification<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The difference is most noticeable when tracking a planet at 150x magnification or more. Without a bearing, you correct in jerks and frequently lose the object from view.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With a roller bearing, the corrections are smooth. You push gently and the telescope follows that movement immediately, without sticking first.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Toolless assembly<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">You loosen the central bolt, lift the rocker box off the base plate, place the bearing around the bolt, and put everything back. That is the whole job.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The bearing consists of an upper and a lower plate with the rolling elements in between, so the components stay in place by themselves.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Check dimensions<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The outer diameter is 320 mm, the inner diameter is 13 mm and the height is 5 mm. Measure your baseplate before ordering: for a Dobson larger than 12 inches, the L version with 460 mm is the right choice.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A laser collimator is the first accessory you need for any Newtonian and Dobson. From an 8-inch aperture, a moon filter adds comfort when observing the full moon.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">For whom yes and for whom no<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>\u2713 Owners of a 6 to 12-inch Dobson<\/li><li>\u2713 Anyone who wants to track objects at high magnification without shaking<\/li><li>\u2713 Observers looking to make a noticeable difference on a small budget<\/li><li>\u2717 Dobsons larger than 12 inch: choose the L version<\/li><li>\u2717 Base plates smaller than 320 mm<\/li><li>\u2717 Whoever wants to improve the elevation movement: this bearing works in azimuth<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Bearing type<\/strong><\/td><td>Roller bearing<\/td><\/tr><tr><td><strong>Suitable for<\/strong><\/td><td>Dobson 6 to 12 inch (rockerbox)<\/td><\/tr><tr><td><strong>Outer diameter<\/strong><\/td><td>320 mm<\/td><\/tr><tr><td><strong>Inside diameter<\/strong><\/td><td>13 mm<\/td><\/tr><tr><td><strong>Height<\/strong><\/td><td>5 mm<\/td><\/tr><tr><td><strong>Material<\/strong><\/td><td>Steel<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">You can find more telescope parts for this brand on the <a href=\"\/en\/brands\/omegon\/\">Omegon brand page<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>Steel roller bearing with top and bottom plate for the rocker box of a 6 to 12-inch Dobsonian.
