Its twin pillow block construction provides increased stability over single-bearing designs, while the self-aligning and adjustable bearing configuration compensates for shaft misalignment. It is widely used in CNC machinery, robotics, semiconductor manufacturing equipment, packaging systems, automated inspection equipment, material handling systems, and OEM linear motion assemblies. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-end=\"1384\" data-start=\"1355\" data-section-id=\"5hg6bl\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-end=\"2924\" data-start=\"1386\"\u003e• Manufacturer: Thomson Industries\u003cbr data-end=\"1422\" data-start=\"1419\"\u003e• Manufacturer Part Number (MPN): TWN12OPN\u003cbr data-end=\"1466\" data-start=\"1463\"\u003e• Product Type: Super Ball Bushing Twin Open Pillow Block Bearing\u003cbr data-end=\"1533\" data-start=\"1530\"\u003e• Series: Super Ball Bushing®\u003cbr data-end=\"1564\" data-start=\"1561\"\u003e• Bearing Style: Open\u003cbr data-end=\"1587\" data-start=\"1584\"\u003e• Pillow Block Type: Twin\u003cbr data-end=\"1614\" data-start=\"1611\"\u003e• Bearing Configuration: Twin Linear Bearing\u003cbr data-end=\"1660\" data-start=\"1657\"\u003e• Housing Material: Aluminum Alloy\u003cbr data-end=\"1696\" data-start=\"1693\"\u003e• Bearing Material: Hardened Steel with Engineered Polymer Retainers\u003cbr data-end=\"1766\" data-start=\"1763\"\u003e• Nominal Bore (ID): 0.750 in (19.05 mm)\u003cbr data-end=\"1808\" data-start=\"1805\"\u003e• Compatible Shaft Class: Class L Continuously Supported Shaft\u003cbr data-end=\"1872\" data-start=\"1869\"\u003e• Overall Length: 4.500 in (114.30 mm)\u003cbr data-end=\"1912\" data-start=\"1909\"\u003e• Overall Width: 2.750 in (69.85 mm)\u003cbr data-end=\"1950\" data-start=\"1947\"\u003e• Body Width: 1.940 in (49.28 mm)\u003cbr data-end=\"1985\" data-start=\"1982\"\u003e• Overall Height: 1.560 in (39.62 mm)\u003cbr data-end=\"2024\" data-start=\"2021\"\u003e• Centerline Height: 0.937 in (23.80 mm)\u003cbr data-end=\"2066\" data-start=\"2063\"\u003e• Mounting Hole Centers: 3.500 in (88.90 mm)\u003cbr data-end=\"2112\" data-start=\"2109\"\u003e• Mounting Hole Diameter: 0.190 in (4.83 mm)\u003cbr data-end=\"2158\" data-start=\"2155\"\u003e• Recommended Bolt Size: #8 (M8 equivalent)\u003cbr data-end=\"2203\" data-start=\"2200\"\u003e• Dynamic Load Capacity: 940 lbf (4,181 N)\u003cbr data-end=\"2247\" data-start=\"2244\"\u003e• Maximum Travel Speed: 10 ft\/sec (3.0 m\/s)\u003cbr data-end=\"2292\" data-start=\"2289\"\u003e• Maximum Operating Temperature: 185°F (85°C)\u003cbr data-end=\"2339\" data-start=\"2336\"\u003e• Weight: 1.0 lb (0.45 kg)\u003cbr data-end=\"2367\" data-start=\"2364\"\u003e• Self-Aligning: Yes\u003cbr data-end=\"2389\" data-start=\"2386\"\u003e• Adjustable: Yes\u003cbr data-end=\"2408\" data-start=\"2405\"\u003e• Number of Ball Circuits: 5\u003cbr data-end=\"2438\" data-start=\"2435\"\u003e• Lubrication Access: 1\/4-28 Lubrication Port\u003cbr data-end=\"2485\" data-start=\"2482\"\u003e• Seals: Both Ends (standard version)\u003cbr data-end=\"2524\" data-start=\"2521\"\u003e• Roll Pack: No\u003cbr data-end=\"2541\" data-start=\"2538\"\u003e• Food Grade Rated: No\u003cbr data-end=\"2565\" data-start=\"2562\"\u003e• Corrosion Resistance: Standard (Not Corrosion Resistant)\u003cbr data-end=\"2625\" data-start=\"2622\"\u003e• Features: Open design for continuously supported shafts, twin pillow block construction, adjustable fit, self-aligning bearing plates, lightweight aluminum housing, engineered polymer retainers, low-friction operation, reduced noise, and extended service life. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-end=\"2950\" data-start=\"2926\" data-section-id=\"1cz0398\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-is-only-node=\"\" data-is-last-node=\"\" data-end=\"3056\" data-start=\"2952\"\u003e• Thomson TWN12OPN-DP\u003cbr data-end=\"2975\" data-start=\"2972\"\u003e• Thomson TWN12OPN-CR\u003cbr data-end=\"2998\" data-start=\"2995\"\u003e• Thomson TWN12OPN-LS\u003c\/p\u003e","brand":"Thomson","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51714013790510,"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_6d109e10-f3e9-4b1f-8a5f-c28bc729a0de.jpg?v=1770413764","url":"https:\/\/plgautomation.com\/products\/thomson-twn12opn-super-twin-pillow-block-ball-bearing-open-shaft-0-75-3-4","provider":"PLG Automation ","version":"1.0","type":"link"}
