Chesterton’s 1210 Ceramic Stationary Seal Face may be used with 891 and 440 rotary seals to form a dual mechanical seal. The 891 is the inboard seal exposed to the process fluid. The 440 is the secondary (outboard) seal that seals barrier fluid to the atmosphere.
Can supply variable barrier pressure through the unit.
Shields the environment from the pumped fluid.
Provides a clean fluid to the inboard seal faces.
Can operate as a pre-installed "stand-by" seal in the event of primary seal maintenance. |

Ceramic balls are particularly suited to harsh environments. Their main advantages over steel is that they have a density of 40% lower than steel. Have 29% lower thermal expansion and are 150% harder. In certain high-speed applications their life is extended by as much as a hundred times. The three main materials used are Alumina Oxide, Zirconia Oxide and Silicon Nitride.

| CERBEC balls are known worldwide for their extremely smooth surface finish. Our manufacturing process is totally dedicated to Si3N4 finishing. This focus yields surface finish typically < 0.10 micro inch (< 0.003 micron) consistently from batch to batch for the tens of millions of balls we produce annually. Reduced bearing friction from Si3N4 is a function of smooth surface finish - it must be done right all at the time. CERBEC balls have over 10 years' history of superior surface finish. |

Flex-Lag® Weld-On Ceramic
Eliminate the belt vibration and cleaner chatter often caused by ordinary weld-on lagging by installing Flex-Lag® Weld-OnCeramic Pulley Lagging. It features a new gutterless design with easily installed over-lapping segments. So the wide gaps between strips of conventional weld-on lagging products are eliminated.
Flex-Lag® Ceramic
When conventional rubber lagging fails to correct belt slippage, the solution is Flex-Lag® Ceramic Tile Lagging. Our Ceramic Tile Lagging features the highest coefficient of friction available in lagging materials - two to three times the friction of rubber in wet, muddy or dry conditions. |

Micro-arc oxidation (MAO) ceramic coating is a revolutionary method to produce hard and corrosion resistant ceramic coatings on Al, Mg, Ti and other light metals as well as their alloys. MAO method uses the effects of forming micro-arc plasma discharges on the surface of the parts treated in water electrolytic solution. Because of influences of these discharges on the parts, a multi-function protective ceramic coating forms with unique properties:
very high hardness (HV1000-2500); excellent wear resistance; excellent corrosion resistance; extremely high adhesion performance of the coating; dielectric property; high thermal shock resistance; ...
We can provide parts treated with such MAO technology, such as roller, shafts and other parts which require high abrasion wear resistance and corrosion resistance. |

Noliac's Ceramic Multilayer Benders products are based on the company's advanced multilayer technology, harnessing the full potential of the piezoelectric effect at very low operating voltages.
Multilayer piezoelectric benders are single co-fired ceramic components with ceramic layers and internal electrodes configured as to generate a bending mode.
The most common bender geometry is a narrow rectangle (CMBP) with typical performance range up to +/- 1500µm stroke and up to 10N blocking force.
Noliac has also developed a unique ring shape bender (CMBR) with typical performances range up to +/- 150µm and up to 100N blocking force.
Multilayer benders are used in numerous applications within e.g. optics, telecommunication, instrumentation, automotive, valves. |
|
Actuators, shear plates (CSAP)
Noliac's line of ceramic shear actuator plates (CSAP) is based on the Noliac Group's advanced piezo technology.
Based on the piezoelectric shear mode, Noliac's shear actuators can be made more compact and have higher resonant frequencies than conventional piezo actuators. In addition, their low capacitance results in reduced power requirements for a given generated displacement in dynamic operation.
Shear actuators are used in numerous applications within e.g. nanopositioning, precision mechanics, active vibration cancellation, semiconductor manufacturing and testing. |

Argweld® Weld Backing Tape
Glass fibre weld backing tape.
The tape would ideally be used for:
One-sided welding of weldable metal.
To achieve a flatter, smooth, coke free weld bead to minimise the need for post-weld grinding and cleaning.
Common metals welded with 'Backing Tape' include:
carbon steels
stainless steel
chrome-moly and duplex steels
copper nickel
cast iron
The tape comprises a 75 mm wide, heat resistant aluminium sticky tape, in the centre of which is a 25 mm wide band of woven glass fibre cloth.
The material is available in two grades:
Standard 80 amp Light duty for use up to 80 amps
Heavy Duty 160 amp Heavy duty for use up to 160 amps
It is possible to weld onto the tape with MIG, Stick, TIG or plasma processes, so long as the recommended current levels are not exceeded.
The lightweight grade comes in 25 metre lengths and the heavyweight in 12.5 meter lengths.
If lengths are needed to be joined, rolls of the sticky aluminium tape without the fiber are available from Huntingdon Fusion Techniques Limited, allowing a small length to be cut off to join two lengths of the 'Backing Tape' together.
