Literature Available On New Pressure-Wiper Seal For Hydraulic Cylinders
Literature is now available describing a new Pressure-Wiper Seal, known as the John Crane Type RH BWC, recently introduced by Crane Packing Company.
One-piece construction consists of a special abrasion-resistant elastomer bonded to a metal reinforcing washer, the internal anti-extrusion ring. Two unique designs provide an O.D. lip for positive seal in bore, a heavyduty I.D. lip for positive rod sealing against fluid pressure and a heavy-duty wiper lip to prevent entry of foreign matter.
The Type RH/BWC Wiper Seal offers a sealing advance over typical "V" packing sets and U-cup arrangements. Benefits include: reduced space requirements, increased bearing space, ease of assembly and disassembly, reduced machining, component and assembly costs and also allows for the use of a shorter cylinder.
Operating conditions include up to 2,500 psi and a temperature range from - 4 0 ° F to +250° F.
Other elastomers are available for special operating conditions.
