{"product_id":"skf-lb40-linear-ball-bearing","title":"SKF LB40 Linear Ball Bearing","description":"\u003cdiv\u003e\u003cp\u003eSKF LB40 Linear Ball Bearing delivers precise, low-friction linear motion on round shafts, featuring a 1-3\/8 inch bore with an overall length of 3-1\/8 inches and a width of 2-3\/8 inches. This LB40 unit is part of SKF's LB series and is designed to ride on a compatible shaft to enable smooth, repeatable travel in compact linear assemblies. With its imperial envelope (ID 1-3\/8\", L 3-1\/8\", W 2-3\/8\"), it suits small- to mid-sized automation, robotics, and CNC guide applications where space is at a premium and positioning accuracy matters. Engineers typically use LB40-sized bearings to define the bearing footprint in an axis package and simplify sourcing for maintenance within the LB family. As a standard SKF component, it integrates with compatible shafting and housing arrangements, enabling straightforward replacement in established linear motion benches and tooling setups. When designing a linear axis, choosing the LB40 size helps balance stiffness, travel, and compactness in tight installations.\u003c\/p\u003e\u003c\/div\u003e","brand":"SKF","offers":[{"title":"New","offer_id":46267860844778,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-016.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/skf-lb40-linear-ball-bearing","provider":"GTG Hardware","version":"1.0","type":"link"}
