The bi-directional, gas-lubri-cated CSR-clearance seal is suitable for installation in all gas-conveying machines. The seal of 17 to 320 mm diameter consists of a split carbon graphite restricting ring that is held together by a tension spring around its circumference. Pockets are worked into the inner surface of the ring to generate a radial lifting force under operating conditions. A concentric gap thus forms automatically as the seal lifts off the shaft. Measuring no more than a few micrometers, this gap is small enough to keep leakage to a minimum. Special features of the radial clearance seal are:
• easy installation thanks to its cartridge design,
• high sliding velocities up to 200 m/s cooled and up to 100 m/s uncooled,
• temperature-independent
operation up to 500 °C and
• usable with gases containing solid particles of grain size up to 10 µm.
