Funktionsweise \u2013 Funktionsprinzip<\/h2>\n

The shear bolt torque limiter operates on a straightforward yet highly effective mechanical principle. A precision-grade shear bolt connects the driving and driven halves of the clutch assembly. Under normal operating conditions, the shear bolt transmits full rotational torque from the PTO shaft to the connected implement. When torque exceeds the bolt’s calibrated shear strength \u2014 caused by a sudden jam, obstruction, or overload \u2014 the bolt shears cleanly at its designed breakpoint. This instantaneously disconnects the driveline, preventing the overload from reaching and damaging expensive downstream components such as gearboxes, bearings, and implement mechanisms. The system resets by simply replacing the sheared bolt with a new one of the correct grade, restoring full operation within minutes.<\/p>\n

Zur\u00fccksetzen-Methode:<\/strong> Manual \u2014 replace shear bolt (supplied in kit)<\/p>\n

Am besten geeignet f\u00fcr:<\/strong> Applications with infrequent overloads where precise trip torque and maximum safety are paramount<\/p>\n

Installation & Usage Guide<\/h2>\n
\n

Installation Steps<\/h3>\n

Step 1:<\/strong> Verify that the PTO shaft spline size matches the torque limiter spline specification (1 3\/8″ Z6, 1 3\/8″ Z6, 1 3\/4″ Z6). Clean all spline surfaces thoroughly.<\/p>\n

Step 2:<\/strong> Slide the torque limiter onto the PTO shaft spline, ensuring full engagement. Secure with the provided push pin kit or retaining hardware.<\/p>\n

Step 3:<\/strong> Connect the output side (yoke or splined shaft) to the implement input shaft or gearbox. Ensure proper alignment and secure all fasteners to the recommended torque.<\/p>\n

Step 4:<\/strong> Apply grease through the grease nipple to lubricate the spline interface and internal components. Use lithium-based EP grease (NLGI #2).<\/p>\n

Step 5:<\/strong> Perform a low-speed test run to verify correct engagement and smooth operation before full-power operation.<\/p>\n

Safety & Maintenance Tips<\/h3>\n

⚠ Always disengage the tractor PTO before inspecting or servicing the torque limiter.<\/p>\n

⚠ Use only genuine replacement parts specified for your series to maintain the correct torque rating.<\/p>\n

⚠ Re-grease spline connections every 8 operating hours or as specified in your equipment manual.<\/p>\n

⚠ Inspect for wear, cracks, or damage before each season. Replace worn components immediately.<\/p>\n

⚠ Never operate with damaged or missing PTO shaft safety shields.<\/p>\n<\/div>\n

<\/p>\n

Selection Guide \u2014 Choosing the Right Model<\/h2>\n
\n

Selecting the correct torque limiter requires confirming the following parameters:<\/p>\n

✓ Required Torque Rating (Nm):<\/strong> Match the implement’s maximum operating torque plus a 20\u201330% safety margin.<\/p>\n

✓ PTO Shaft Spline Size:<\/strong> Commonly 1 3\/8″ Z6 (6-spline) or 1 3\/4″ Z6\/Z20. Verify both input and output spline requirements.<\/p>\n

✓ PTO Speed:<\/strong> Standard 540 RPM or economy 1000 RPM \u2014 confirm your implement’s requirement.<\/p>\n

✓ Connection Type:<\/strong> Yoke output for standard shaft tubes, splined shaft for inline assemblies, or flanged output for direct gearbox mounting.<\/p>\n

✓ Overload Frequency:<\/strong> Frequent overloads favor auto-reset types (ratchet, friction, automatic). Infrequent but severe overloads suit shear bolt types.<\/p>\n

✓ Environmental Conditions:<\/strong> Consider dust, moisture, temperature extremes. Sealed automatic and friction types offer superior protection in harsh environments.<\/p>\n

<\/p>\n

Frequently Asked Questions (FAQ)<\/h2>\n
\n
\n
\nWhat torque rating do I need for my implement?<\/summary>\n
\n

The required torque rating depends on your implement’s maximum operating torque. As a general rule, select a torque limiter rated at 1.2 to 1.5 times the implement’s normal peak operating torque. Consult your implement manufacturer’s specifications or contact our engineering team for personalized guidance.<\/p>\n<\/div>\n<\/details>\n<\/div>\n

\n
\nHow do I know when the torque limiter has activated?<\/summary>\n
\n

Depending on the type: shear bolt limiters show a visibly sheared bolt; ratchet limiters produce a distinct clicking sound during slip; friction limiters emit a slight odor and sound during sustained slipping; automatic cam limiters produce a clicking sensation. In all cases, the implement stops receiving power while the PTO shaft continues turning.<\/p>\n<\/div>\n<\/details>\n<\/div>\n

\n
\nCan I adjust the torque setting?<\/summary>\n
\n

Friction-type and automatic (cam-type) torque limiters allow field adjustment of the torque setting by changing spring preload through bolt tension. Shear bolt types are set by the bolt grade and cannot be adjusted \u2014 different torque ratings require different bolt specifications. Ratchet types have a fixed setting determined by the number and spring rate of the pawls.<\/p>\n<\/div>\n<\/details>\n<\/div>\n

\n
\nWhat maintenance does the torque limiter require?<\/summary>\n
\n

Regular greasing through the grease nipple (every 8 operating hours), visual inspection for wear or damage before each season, and replacement of worn friction linings (friction types) or keeping spare shear bolts on hand (shear bolt types). Automatic and ratchet types require minimal maintenance beyond lubrication.<\/p>\n<\/div>\n<\/details>\n<\/div>\n

\n
\nIs this torque limiter compatible with my PTO shaft?<\/summary>\n
\n

This product uses standard 1 3\/8″ Z6, 1 3\/8″ Z6, 1 3\/4″ Z6 spline connections, which are compatible with the vast majority of agricultural PTO shafts worldwide. If your equipment uses a different spline configuration, we offer adapters and custom spline options. Contact us with your shaft specifications for confirmation.<\/p>\n<\/div>\n<\/details>\n<\/div>\n

\n
\nWhat is the difference between 540 RPM and 1000 RPM PTO?<\/summary>\n
\n

Standard PTO operates at 540 RPM and is used for most agricultural implements. Economy PTO (also called 1000 RPM PTO) is used for lighter implements to reduce engine RPM and fuel consumption. Our torque limiters are rated for both speeds. Select the spline size matching your PTO standard: typically 1 3\/8″ Z6 for 540 RPM and 1 3\/4″ Z20 for 1000 RPM.<\/p>\n<\/div>\n<\/details>\n<\/div>\n

\n
\nDo you offer OEM and private-label manufacturing?<\/summary>\n
\n

Yes, we provide full OEM manufacturing services including custom torque ratings, special spline configurations, custom markings, and private-label packaging. Minimum order quantities apply.

Der SB\/SBT1 Series Shear Bolt Torque Limiter<\/strong> is a mechanical overload protection device designed for PTO drive shafts<\/strong> in agricultural and industrial machinery. It safeguards expensive gearboxes, implements, and tractor PTOs from catastrophic damage caused by sudden torque spikes, jamming, or overloading. When the preset torque threshold (570\u20134500 Nm) is exceeded, the calibrated shear bolt fractures cleanly, immediately disconnecting the driveline and preventing costly equipment failure and hazardous situations. This series stands out for its simple reset process<\/em> \u2014 just replace the shear bolt \u2014 and its precise, repeatable trip point<\/em>. With a 1 3\/8″ Z6 spline interface and a full range of torque ratings, the SB series fits virtually any standard PTO shaft application.<\/p>","protected":false},"featured_media":1675,"comment_status":"closed","ping_status":"open","template":"","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":""},"product_brand":[],"product_cat":[5052],"product_tag":[5057,5061,5058,5062,5055,5060,5053,5056,5059,5054],"class_list":{"0":"post-1815","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-shear-bolt-torque-limiter","7":"product_tag-agricultural-pto-torque-limiter","8":"product_tag-farm-equipment-torque-limiter","9":"product_tag-pto-drive-shaft-shear-bolt-clutch","10":"product_tag-pto-driveline-safety-device","11":"product_tag-pto-shaft-safety-clutch","12":"product_tag-pto-shaft-shear-pin-coupling","13":"product_tag-pto-shear-bolt-torque-limiter","14":"product_tag-shear-pin-overload-protector","15":"product_tag-tractor-implement-overload-protection","16":"product_tag-tractor-pto-slip-clutch","18":"first","19":"instock","20":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/limitertorque.com\/de\/wp-json\/wp\/v2\/product\/1815","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/limitertorque.com\/de\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/limitertorque.com\/de\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/limitertorque.com\/de\/wp-json\/wp\/v2\/comments?post=1815"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/limitertorque.com\/de\/wp-json\/wp\/v2\/media\/1675"}],"wp:attachment":[{"href":"https:\/\/limitertorque.com\/de\/wp-json\/wp\/v2\/media?parent=1815"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/limitertorque.com\/de\/wp-json\/wp\/v2\/product_brand?post=1815"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/limitertorque.com\/de\/wp-json\/wp\/v2\/product_cat?post=1815"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/limitertorque.com\/de\/wp-json\/wp\/v2\/product_tag?post=1815"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
