Its twin pillow block configuration provides greater rigidity than a single bearing, while the adjustable housing allows precise diametrical fit-up for improved accuracy and repeatability. It is widely used in CNC machinery, packaging systems, robotics, semiconductor manufacturing equipment, inspection machines, material handling systems, and OEM linear motion assemblies. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1346\" data-end=\"1375\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1377\" data-end=\"2993\"\u003e• Manufacturer: Thomson Industries\u003cbr data-start=\"1410\" data-end=\"1413\"\u003e• Manufacturer Part Number (MPN): TWN12ADJ\u003cbr data-start=\"1454\" data-end=\"1457\"\u003e• Product Type: Super Ball Bushing Twin Adjustable Pillow Block Bearing\u003cbr data-start=\"1527\" data-end=\"1530\"\u003e• Series: Super Ball Bushing®\u003cbr data-start=\"1558\" data-end=\"1561\"\u003e• Bearing Style: Closed\u003cbr data-start=\"1583\" data-end=\"1586\"\u003e• Pillow Block Type: Twin Adjustable\u003cbr data-start=\"1621\" data-end=\"1624\"\u003e• Bearing Configuration: Twin Linear Bearing\u003cbr data-start=\"1667\" data-end=\"1670\"\u003e• Housing Material: Aluminum\u003cbr data-start=\"1697\" data-end=\"1700\"\u003e• Bearing Material: Hardened Steel with Engineered Polymer Retainers\u003cbr data-start=\"1767\" data-end=\"1770\"\u003e• Nominal Bore (ID): 0.750 in (19.05 mm)\u003cbr data-start=\"1809\" data-end=\"1812\"\u003e• Compatible Shaft Class: Class L Round Shaft\u003cbr data-start=\"1856\" data-end=\"1859\"\u003e• Overall Length (B): 4.500 in (114.30 mm)\u003cbr data-start=\"1900\" data-end=\"1903\"\u003e• Overall Width (A): 2.750 in (69.85 mm)\u003cbr data-start=\"1942\" data-end=\"1945\"\u003e• Body Width (A2): 1.880 in (47.75 mm)\u003cbr data-start=\"1982\" data-end=\"1985\"\u003e• Overall Height (H1): 1.750 in (44.45 mm)\u003cbr data-start=\"2026\" data-end=\"2029\"\u003e• Body Height (F): 1.560 in (39.62 mm)\u003cbr data-start=\"2066\" data-end=\"2069\"\u003e• Centerline Height (G): 0.940 in (23.88 mm)\u003cbr data-start=\"2112\" data-end=\"2115\"\u003e• Centerline Height (H): 0.937 in (23.80 mm)\u003cbr data-start=\"2158\" data-end=\"2161\"\u003e• Mounting Hole Centers (E2): 3.500 in (88.90 mm)\u003cbr data-start=\"2209\" data-end=\"2212\"\u003e• Mounting Hole Diameter (N): 0.190 in (4.83 mm)\u003cbr data-start=\"2259\" data-end=\"2262\"\u003e• Recommended Mounting Bolt: #8\u003cbr data-start=\"2292\" data-end=\"2295\"\u003e• Lubrication Port: 1\/4-28 Thread\u003cbr data-start=\"2327\" data-end=\"2330\"\u003e• Dynamic Load Capacity: 1,200 lbf (5,338 N)\u003cbr data-start=\"2373\" data-end=\"2376\"\u003e• Maximum Travel Speed: 10 ft\/sec (3.0 m\/s)\u003cbr data-start=\"2418\" data-end=\"2421\"\u003e• Maximum Operating Temperature: 185°F (85°C)\u003cbr data-start=\"2465\" data-end=\"2468\"\u003e• Weight: 1.20 lb (0.544 kg)\u003cbr data-start=\"2495\" data-end=\"2498\"\u003e• Self-Aligning: Yes\u003cbr data-start=\"2517\" data-end=\"2520\"\u003e• Adjustable: Yes\u003cbr data-start=\"2536\" data-end=\"2539\"\u003e• Seals: Integral Double-Acting Seals\u003cbr data-start=\"2575\" data-end=\"2578\"\u003e• Roll Pack: No\u003cbr data-start=\"2592\" data-end=\"2595\"\u003e• Food Grade Rated: No\u003cbr data-start=\"2616\" data-end=\"2619\"\u003e• Corrosion Resistance: Standard (Not Corrosion Resistant)\u003cbr data-start=\"2676\" data-end=\"2679\"\u003e• Features: Adjustable pillow block for precise bearing preload, twin bearing construction, self-aligning bearing plates, lightweight aluminum housing, engineered polymer retainers, lubrication access, low-friction operation, reduced operating noise, and extended service life. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2995\" data-end=\"3019\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"3021\" data-end=\"3118\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• Thomson TWN12\u003cbr data-start=\"3035\" data-end=\"3038\"\u003e• Thomson TWN12OPN\u003cbr data-start=\"3055\" data-end=\"3058\"\u003e• Thomson TWN12ADJ-CRDP\u003c\/p\u003e","brand":"Thomson","offers":[{"title":"New","offer_id":51714013757742,"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_34f007a3-b85a-4e28-b692-6a86db553407.jpg?v=1770413762","url":"https:\/\/plgautomation.com\/products\/thomson-twn12adj-super-ball-bushing-bearing-twin-pillow-block","provider":"PLG Automation ","version":"1.0","type":"link"}
