Its primary function is to enable the anchoring and adaptation of mounting rails for pipe fastening systems. Designed for integration with STAUFF DIN 4S (Group 2) and STAUFF DIN 5S (Group 3), this adaptor operates in conjunction with other Heavy Series metal components to reduce vibration and ensure structural stability in hydraulic systems.<\/p>\n<h3>Construction Features and Materials<\/h3>\n<p>The STAUFF Heavy Series Channel Rail Adaptor Type CRA is part of an ecosystem of metal components (Further Metal Hardware) that share strict construction standards. Heavy Series hardware is typically available in various highly specialised finishes and materials, including:<\/p>\n<ul>\n<li>Uncoated carbon steel (Code W1).<\/li>\n<li>Zinc\/nickel-plated carbon steel (Code W3), which represents the standard finish option for the North American market.<\/li>\n<li>V2A Stainless Steel 1.4301\/1.4305 \/ AISI 304\/303 (Code W4).<\/li>\n<li>V4A Stainless Steel 1.4401\/1.4571 \/ AISI 316\/316 Ti (Code W5).<\/li>\n<\/ul>\n<p>These material variants ensure high corrosion resistance and excellent tolerance to continuous exposure to industrial hydraulic fluids.<\/p>\n<h3>Applications and Sectors<\/h3>\n<p>The STAUFF Heavy Series Channel Rail Adaptor Type CRA is specifically intended for Fluid Contamination Control systems and Hydraulic Components subjected to heavy loads and vibration. Its documented use with Groups 4S and 5S ensures that the component is structurally suitable for high-pressure operating environments typical of heavy industry. This adaptor facilitates installation in combination with STSV mounting rails.<\/p>\n<h3>System Specifications and Compatibility<\/h3>\n<p>This adaptor is designed exclusively for use with the Heavy Twin Series and integrates seamlessly with other components from the same range to form a complete fastening assembly. For correct use, the system requires combination with precisely sized and standardised components. The anchoring system integrates with:<\/p>\n<ul>\n<li>Type AS Hexagon Head Bolts according to DIN 931\/933 or ANSI\/ASME B18.2.1 (e.g. with ISO Metric M10x60, M10x70 or Unified Coarse UNC 3\/8-16 threads).<\/li>\n<li>Type GMV Mounting Rail Nuts (Groups 4S and 5S).<\/li>\n<li>Type STSV Mounting Rails.<\/li>\n<li>Type IS Hexagon Socket Head Cap Screws.<\/li>\n<li>Type SIPD Safety Locking Plates.<\/li>\n<li>Type AF Stacking Bolts.<\/li>\n<\/ul>\n<p>For configurations subjected to extreme stresses, the use of Type SI Safety Lock Washers is recommended to prevent mechanical connections from loosening. The complete assembly ensures optimised fastening and maximum interconnection between the support rails and the pipework.<\/p>\n<h3>Summary Technical Table of the Main Features of the STAUFF Heavy Series Channel Rail Adaptor Type CRA<\/h3>\n<div style=\"width: 100%; overflow-x: auto;\">\n<table style=\"width: 100%; border-collapse: collapse;\">\n<thead>\n<tr>\n<th style=\"border: 1px solid #ddd; padding: 8px; text-align: left; background-color: #f2f2f2;\">Feature<\/th>\n<th style=\"border: 1px solid #ddd; padding: 8px; text-align: left; background-color: #f2f2f2;\">Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Product Family<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Heavy Twin Series \/ Heavy Series<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Compatible STAUFF Groups<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">4S and 5S<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Corresponding DIN Groups<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">2 (for 4S), 3 (for 5S)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Compatible Associated Hardware<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Mounting Rail STSV, Nut GMV, Bolt AS, Screw IS<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Available System Materials<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">W1, W3, W4, W5<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Operating Sector<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Hydraulic Components &amp; Fluid Contamination Control<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<h3>Product Codes<\/h3>\n<div style=\"width: 100%; overflow-x: auto;\">\n<table style=\"width: 100%; border-collapse: collapse;\">\n<thead>\n<tr>\n<th style=\"border: 1px solid #ddd; padding: 8px; text-align: left; background-color: #f2f2f2;\">Model \/ Family<\/th>\n<th style=\"border: 1px solid #ddd; padding: 8px; text-align: left; background-color: #f2f2f2;\">Series<\/th>\n<th style=\"border: 1px solid #ddd; padding: 8px; text-align: left; background-color: #f2f2f2;\">STAUFF Group<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Type CRA &#8211; Group 4S<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Heavy Series<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">4S (DIN 2)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Type CRA &#8211; Group 5S<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Heavy Series<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">5S (DIN 3)<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n","protected":false},"excerpt":{"rendered":"<p>An essential component for the installation of hydraulic fastening systems, the STAUFF Heavy Series Channel Rail Adaptor Type CRA is designed for the Heavy Twin Series.
