It provides smooth rolling motion, high rigidity, and long service life for cam mechanisms, guide rollers, conveyors, and automated machinery. Commonly installed in packaging equipment, industrial automation systems, machine tools, material handling equipment, and indexing mechanisms. Maintenance teams and machine builders use this cam follower for equipment repair, replacement, and new machine construction. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"674\" data-end=\"691\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"693\" data-end=\"1280\"\u003eThe THK CFN 8R-A belongs to the THK CFN-R-A Series of cam followers containing thrust ball bearings. Unlike standard cam followers, the CFN series incorporates thrust-load ball bearings inside the stud, effectively preventing friction and wear on the stud shoulder when axial (thrust) loads occur due to installation misalignment or side loading. The \"R\" suffix denotes a spherical outer ring profile for improved alignment with mating surfaces, while the \"A\" suffix identifies the hexagon socket stud-head configuration for convenient installation. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1282\" data-end=\"1311\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1313\" data-end=\"2173\"\u003e• Brand: THK\u003cbr data-start=\"1325\" data-end=\"1328\"\u003e• Part Number: CFN 8R-A\u003cbr data-start=\"1351\" data-end=\"1354\"\u003e• Product Type: Cam Follower Bearing\u003cbr data-start=\"1390\" data-end=\"1393\"\u003e• Series: CFN-R-A (Containing Thrust Balls)\u003cbr data-start=\"1436\" data-end=\"1439\"\u003e• Bearing Type: Stud-Type Cam Follower\u003cbr data-start=\"1477\" data-end=\"1480\"\u003e• Stud Diameter: 8 mm\u003cbr data-start=\"1501\" data-end=\"1504\"\u003e• Thread Size: M8 × 1.25\u003cbr data-start=\"1528\" data-end=\"1531\"\u003e• Outer Diameter (D): 19 mm\u003cbr data-start=\"1558\" data-end=\"1561\"\u003e• Outer Ring Width (C): 11 mm\u003cbr data-start=\"1590\" data-end=\"1593\"\u003e• Inner Width (B): 12 mm\u003cbr data-start=\"1617\" data-end=\"1620\"\u003e• Overall Length (B1): 32 mm\u003cbr data-start=\"1648\" data-end=\"1651\"\u003e• Thread Length (G1): 10 mm\u003cbr data-start=\"1678\" data-end=\"1681\"\u003e• Outer Ring Profile: Spherical (R)\u003cbr data-start=\"1716\" data-end=\"1719\"\u003e• Stud Head: Hexagon Socket (A)\u003cbr data-start=\"1750\" data-end=\"1753\"\u003e• Basic Dynamic Load Rating (C): 4.17 kN\u003cbr data-start=\"1793\" data-end=\"1796\"\u003e• Basic Static Load Rating (C₀): 4.65 kN\u003cbr data-start=\"1836\" data-end=\"1839\"\u003e• Lubrication: Grease lubricated (optional dedicated grease nipple available)\u003cbr data-start=\"1916\" data-end=\"1919\"\u003e• Material: High-carbon bearing steel\u003cbr data-start=\"1956\" data-end=\"1959\"\u003e• Features: Integrated thrust ball bearings, spherical outer ring for improved alignment, compact stud-type design, high rigidity, smooth rolling motion, and long service life. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2175\" data-end=\"2199\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2201\" data-end=\"2326\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• THK CF 8R-A Cam Follower\u003cbr data-start=\"2227\" data-end=\"2230\"\u003e• THK CFH 8R-A Cam Follower\u003cbr data-start=\"2257\" data-end=\"2260\"\u003e• THK CFN 10R-A Cam Follower\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"THK","offers":[{"title":"New","offer_id":51713989542190,"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_b3f58838-f5b1-48b7-b08f-70781c58b7bb.jpg?v=1770413119","url":"https:\/\/plgautomation.com\/products\/thk-co-ltd-cfn-8r-a-cam-follower-stud-type","provider":"PLG Automation ","version":"1.0","type":"link"}
