STAUFF Heavy Series Channel Rail Adaptor Type CRA

Description

Introduction and Operating Principle

The component identified as the STAUFF Heavy Series Channel Rail Adaptor Type CRA represents a fundamental connecting element within the Heavy Twin Series component family. 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.

Construction Features and Materials

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:

• Uncoated carbon steel (Code W1).
• Zinc/nickel-plated carbon steel (Code W3), which represents the standard finish option for the North American market.
• V2A Stainless Steel 1.4301/1.4305 / AISI 304/303 (Code W4).
• V4A Stainless Steel 1.4401/1.4571 / AISI 316/316 Ti (Code W5).

These material variants ensure high corrosion resistance and excellent tolerance to continuous exposure to industrial hydraulic fluids.

Applications and Sectors

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.

System Specifications and Compatibility

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:

• 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).
• Type GMV Mounting Rail Nuts (Groups 4S and 5S).
• Type STSV Mounting Rails.
• Type IS Hexagon Socket Head Cap Screws.
• Type SIPD Safety Locking Plates.
• Type AF Stacking Bolts.

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.
