An annular disc surrounds a shaft, port or central fastener with a woven filtering ring. Dimension outside diameter D and centre-hole diameter d from the same datum and state concentricity. Radial width is (D−d)/2. Identify inner and outer sealing lands separately: edge capture reduces the exposed ring width at both boundaries.

An annular disc surrounds a shaft, port or central fastener with a woven filtering ring. Dimension outside diameter D and centre-hole diameter d from the same datum and state concentricity. Radial width is (D−d)/2. Identify inner and outer sealing lands separately: edge capture reduces the exposed ring width at both boundaries.
For D = 100 mm and d = 40 mm, radial width is 30 mm and gross annular area is π(D²−d²)/4=6597 mm². A 40-mesh square weave with 0.25 mm wire has 0.385 mm aperture and 36.8% geometric open area. Combining these geometries gives about 2425 mm² before edge capture and support blockage. These are worked dimensions; the mounting drawing defines the finished ring.
Single layers fit a continuously supported seat; multilayer rings place the fine filtering layer against the specified support sequence. Bare-cut, joined or rimmed edges are defined independently for the inner and outer boundaries. Inspect loose wire ends at the central passage, concentricity, both edge profiles and total thickness. Mark the support face and flow direction so installation restores the designed contact and seal.
The cloth family includes stainless steel, copper, nickel, Monel and Inconel woven mesh. Specify the alloy grade for each cloth layer. Metal edge strips include stainless steel, copper, galvanized steel, aluminium and low-carbon steel; rubber and plastic coverings form separate perimeter options. The rim material, joint and cleaning chemistry are specified independently of the filtering cloth.
| Component | Definition |

| Drawing example | D100 mm; d40 mm; (D−d)/2=30 mm |
| Gross ring area and open mesh area | π(D²−d²)/4=6597 mm² |
| Square-weave example | 25.4/40−0.25=0.385 mm; (0.385/0.635)²=36.8% |
| Gross ring area and open mesh area × Net cloth fraction | 6597×(0.385/0.635)²≈2425 mm² |

Materials: The cloth family includes stainless steel, copper, nickel, Monel and Inconel woven mesh. Specify the alloy grade for each cloth layer. Metal edge strips include stainless steel, copper, galvanized steel, aluminium and low-carbon steel; rubber and plastic coverings form separate perimeter options. The rim material, joint and cleaning chemistry are specified independently of the filtering cloth.
The ring is cut from specified wire cloth as a single layer or a supported stack. Edge finishing prevents stray wires entering the central passage or the sealing land.
Include these details when discussing your requirements.
An annular disc surrounds a shaft, port or central fastener with a woven filtering ring. Dimension outside diameter D and centre-hole diameter d from the same datum and state concentricity. Radial width is (D−d)/2. Identify inner and outer sealing lands separately: edge capture reduces the exposed ring width at both boundaries.
Single layers fit a continuously supported seat; multilayer rings place the fine filtering layer against the specified support sequence. Bare-cut, joined or rimmed edges are defined independently for the inner and outer boundaries. Inspect loose wire ends at the central passage, concentricity, both edge profiles and total thickness. Mark the support face and flow direction so installation restores the designed contact and seal.
Cutting and edge capture define the finished outside and inside diameters. Inspect both against the common centre datum, together with seating flatness and the retained filtering width.
The drawing assigns it to a shaft, port or fixing interface and specifies clearance. The surrounding ring provides the filtering area; inner and outer lands define the bypass barriers.
