The BLK2020 model features a 20 mm screw shaft diameter and a 20 mm lead, making it suitable for applications requiring high travel speed and efficient linear motion. The \"ZZ\" suffix indicates double seals on the ball nut to help prevent contaminant ingress and retain lubricant. The 2877 designation represents the overall screw shaft length of 2,877 mm. This ball screw is commonly used in automated conveyors, transfer units, pick-and-place systems, packaging equipment, and other industrial automation machinery where long-stroke, high-speed positioning is required. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1419\" data-end=\"1448\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1450\" data-end=\"2249\"\u003e• Brand: THK\u003cbr data-start=\"1462\" data-end=\"1465\"\u003e• Part Number: BLK2020DZZ-2877\u003cbr data-start=\"1495\" data-end=\"1498\"\u003e• Product Type: Full-Ball Rolled Ball Screw Assembly\u003cbr data-start=\"1550\" data-end=\"1553\"\u003e• Series: BLK (Large Lead)\u003cbr data-start=\"1579\" data-end=\"1582\"\u003e• Screw Shaft Diameter: 20 mm\u003cbr data-start=\"1611\" data-end=\"1614\"\u003e• Lead: 20 mm\u003cbr data-start=\"1627\" data-end=\"1630\"\u003e• Overall Screw Length: 2,877 mm\u003cbr data-start=\"1662\" data-end=\"1665\"\u003e• Ball Nut Type: End-Cap Recirculation\u003cbr data-start=\"1703\" data-end=\"1706\"\u003e• Seal Type: ZZ (Double End Seals)\u003cbr data-start=\"1740\" data-end=\"1743\"\u003e• Preload: None (Standard BLK Series)\u003cbr data-start=\"1780\" data-end=\"1783\"\u003e• Dynamic Load Rating: 11.1 kN (BLK2020-3.6 configuration)\u003cbr data-start=\"1841\" data-end=\"1844\"\u003e• Static Load Rating: 24.7 kN (BLK2020-3.6 configuration)\u003cbr data-start=\"1901\" data-end=\"1904\"\u003e• DN Value: 70,000\u003cbr data-start=\"1922\" data-end=\"1925\"\u003e• Motion Type: Rotary-to-Linear Motion\u003cbr data-start=\"1963\" data-end=\"1966\"\u003e• Lubrication: Grease or Oil Compatible\u003cbr data-start=\"2005\" data-end=\"2008\"\u003e• Material: Hardened Alloy Steel\u003cbr data-start=\"2040\" data-end=\"2043\"\u003e• Features: Large lead for high-speed travel, high mechanical efficiency, low friction, end-cap ball recirculation, precision rolled screw shaft, and long service life. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2251\" data-end=\"2275\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2277\" data-end=\"2397\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• THK BLK2020DZZ-3000\u003cbr data-start=\"2298\" data-end=\"2301\"\u003e• THK BLK2020DZZ-2500\u003cbr data-start=\"2322\" data-end=\"2325\"\u003e• THK BLK2525DZZ Series Ball Screw\u003c\/p\u003e","brand":"THK","offers":[{"title":"New","offer_id":51713989902638,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_2d0f683f-71f0-4e6b-b1f6-851bb0c59a67.jpg?v=1770413133","url":"https:\/\/plgautomation.com\/products\/thk-blk2020dzz-2877-full-ball-rolled-ball-screw-assembly","provider":"PLG Automation ","version":"1.0","type":"link"}
