Technical details and manufacturing context for Air Supply Manifold

Definition

The Air Supply Manifold is a critical component of an Air Bearing System, responsible for receiving compressed air from the main supply line and evenly distributing it to individual air bearings or bearing zones. It ensures consistent pressure and flow to each outlet, which is essential for maintaining the precise levitation and frictionless motion characteristic of air bearing technology. The manifold is typically manufactured from aluminum alloy (e.g. 6061-T6, anodized) or stainless steel, with port sizes ranging from G1/8 to G1/2 (BSPP threads per ISO 228-1). It is designed for operating pressures between 1.0 and 1.6 MPa, with a leak rate not exceeding 0.01 MPa·L/s at 1.0 MPa internal pressure (ISO 27895). The number of outlets can be configured from 4 to 12, and the flow rate per outlet (Cv) ranges from 0.5 to 2.5 at a 0.1 MPa pressure drop. The manifold operates within a temperature range of -40°C to 85°C (non-condensing) and features sealing surfaces with a surface finish of Ra 0.8–1.6 µm (ISO 1302). Dimensions vary with outlet count, from 100×60×40 mm to 300×100×80 mm, and weight ranges from 0.5 to 2.5 kg. These specifications are reference values; actual values must be confirmed with the manufacturer for the specific model and application. The manifold is a component, not a standalone product, and its performance depends on proper integration with the air bearing system, including correct inlet pressure, outlet connections, and system cleanliness. Regular inspection for leaks, pressure drops, and surface wear is recommended to maintain system stability. For procurement, verify that the manifold meets the required standards and specifications for your application.

Working Principle

Compressed air enters the manifold through a primary inlet. Internal channels and chambers within the manifold body divide and direct the airflow to multiple outlet ports. The design aims to minimize pressure drop and ensure balanced flow distribution to all connected air bearings, maintaining system stability and performance. The manifold's internal geometry is engineered to achieve uniform flow, and the surface finish of sealing surfaces (Ra 0.8–1.6 µm) helps maintain seal integrity. The flow rate per outlet (Cv) is a key parameter for sizing, and the number of outlets affects overall flow distribution. Proper installation and maintenance are essential to prevent pressure drops and ensure consistent performance.
