Multiple bolts can be tensioned simultaneously.<br \/>\nTorque-free tensioning design eliminates the effects of friction and bolt twisting on preload, ensuring that the bolt is subjected to pure tensile force.<br \/>\nPreload can be set accurately, with accuracy up to \u00b13%.<br \/>\nEquipped with a stroke indicator, allowing the operator to observe, measure, and control bolt elongation during operation.<br \/>\nApplications<br \/>\nHD Series Hydraulic Nuts are suitable for applications involving bolts that require frequent assembly and disassembly, preloading of extra-large bolts, and locking of large workpieces.<br \/>\nThey can also be used as hydraulic tools for the assembly and disassembly of interference-fit components. Installing or removing bearings on tapered shafts or sleeves is often difficult and time-consuming. Hydraulic nuts significantly simplify this process and improve operating efficiency.<br \/>\nHigh-pressure hydraulic oil is supplied to the hydraulic nut by a high-pressure pump, generating force to drive the piston. This controlled axial force enables bearings and other interference-fit components to be installed or removed accurately, efficiently, and safely.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Product Features Suitable bolt sizes: M22\u2013M100 Maximum  [&hellip;]<\/p>\n","protected":false},"featured_media":505,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[17],"product_tag":[],"class_list":["post-1211","product","type-product","status-publish","has-post-thumbnail","product_cat-hydraulic-bolt-tensioners","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product\/1211","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/comments?post=1211"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/media\/505"}],"wp:attachment":[{"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/media?parent=1211"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product_brand?post=1211"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product_cat?post=1211"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product_tag?post=1211"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
