Configured as a 3:1 belt-drive rotary with a 100 mm diameter stage, it presents a 50 mm tall profile and includes a through-hole aperture of Ø16 mm for cabling and center clearance. The unit uses preloaded duplex angular-contact bearings to maintain rigidity and minimize runout, while feedback comes from a 16KCPR rotary motor encoder to provide deterministic positioning. The Ø16 mm through-hole and precise bearing\/drive arrangement support stable repeatability in metrology, optical alignment, and precision instrumentation, and Bell-Everman notes that ServoBelt rotary stages are commonly employed in metrology and semiconductor manufacturing environments. For applications requiring even higher angular resolution, optional high-precision encoders such as Renishaw ring encoders or tape scales can be configured to enhance resolution on partial-rotation tasks. \u003c\/p\u003e\u003c\/div\u003e","brand":"Bell-Everman","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676873589038,"sku":null,"price":725.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_e64963ec-f2fa-480a-8dc8-6cb56e52d71d.jpg?v=1769554618","url":"https:\/\/plgautomation.com\/products\/bell-everman-sbr-16-31-servobelt-rotary-actuator","provider":"PLG Automation ","version":"1.0","type":"link"}
