The Timken SLJI8QMTU3-7/16 Take-Up Block with an eccentric locking collar provides secure shaft support and adjustable belt or chain tension for heavy-duty conveyor and industrial power transmission systems. This wide-slot take-up block features a solid cast housing (cast iron) and a 3-7/16 in. shaft size, with a locking collar that securely retains the shaft while allowing precise positioning for tensioning. It uses a solid-block mounted spherical roller bearing (bearing number 22218) and is grease lubricated, relubricatable, to support demanding operating conditions. Key ratings include a dynamic load capacity of 79,700 lbf (355,000 N) and a static load capacity of 87,200 lbf (388,000 N), making it suitable for continuous-duty service in environments where contamination, shock loads, and heavy use are common. The unit is part of the Timken QMTU EC Series and is commonly employed in mining, aggregate processing, food processing, agriculture, manufacturing, and material handling where adjustable shaft positioning and reliable take-up are required. Common replacements include Timken QMTU18J307S, QMTU18J307SM, and QMTU18J307SN for retrofit or replacement.
