Heating bands are the ideal solution for the heating of tubes an cylinders. Mica band heaters, frequently used as nozzle heaters, are made with a plastic-tight stainless steel casing. Such mica heating bands are in many dimension available from stock. The Ceramic heating band type is suitable specially for applications with high watt density and therefore for higher temperatures. Ceramic band heaters, also known as ceramic ring heaters or cylindrical ceramic sectional heaters, are attached to the contact surface by means of a clamping mechanism. A preferred field of use for ceramic band heaters is the heating of plasticising cylinders, bushings and nozzles of injection moulding machines and screw barrels of extrusion machines. For thermal optimization and process control ceramic band heaters can also be offered with insulation jackets or air cooling.

Ceramic Insulated (Band) Heaters are predestined for high-temperature applications beyond 450 °C, for example for pipe heating in process heat technology, especially when gases are involved. Ceramic insulated sectional surface heating elements are also brought into action where a heat storage capacity is needed, as in hot plates the case. With the heating surface of ceramic flat heaters being composed by small-limbed ceramic elements with aligned holes in the centre for the resistance coils to be fed through, ceramic sectional heating mats are also applicable for bent or cylindric surfaces. Like Micanite insulated flat heating elements also Ceramic insulated elements can receive a metal sheath. The latter provides additional protection against mechanical load and allows for attaching connection boxes. Another advantage is the easy installation by means of mounting holes in the metal cladding.

"Ball bearings with a material combination of bearing steel (inner and outer rings) and ceramic (balls) are called ‘hybrid’ ball bearings. All GMN ball bearings can be supplied as hybrid ball bearings. The material characteristics of ceramic balls in hybrid ball bearings result in significant increases in machine performance (in comparison to ball bearings using steel balls), especially under critical conditions.

The compression-type fittings are the link between the thermocouple and the test area and facilitate precise adaptation. After installing the compression-type fitting, the thermocouple can be inserted and clamped in with the desired installation length. That makes it possible to perform individual measurements with self-defined installation lengths directly onsite.

ALWA MOULD P is a cold curing casting resin for the production of porous moulds, slabs and blocks for the ceramic industry. It is a porous and high-strength plastic, which is well-suited for high pressure casting applications. ALWA MOULD P can be used in various areas of the tableware and sanitary ceramics, technical ceramics, plastic mould procedure as well as various filtration processes. The high stability and defined porosity of the material allows highly accurate mould surface reproductions. With ALWA MOULD P various geometric moulds for filtration processes of suspensions can be produced. ALWA MOULD P can be used for ceramic slip pressure casting procedures. In this procedure, water is removed by a filtration process of a clay suspension (slip), so that an increasing clay layer is built on the mould wall over time. The moulds, slabs and blocks of ALWA MOULD P are easily machinable (e.g., drilling, milling).

The CM-Sensors are specially designed for demanding applications: They withstand high pressures up to 100 bars (and more) at temperatures up to 190 °C. At conventional sensors with a similar size the probe head must be kept free from surrounding conductive objects, in order to avoid pre-attenuation of the measuring system. In contrast, the socket for the CM-sensor does not require additional notches or holes.This feature arises from the utilization of zirconium oxide as housing material and ferritic components with a focusing effect. The CM-sensor is typically applied to monitor the orbit of a turbocharger’s shaft.Its ball bearings have a squeeze film damper to reduce the rotor vibration. In order to optimize the entire system the CM-sensors detect the exact position of the turbine- and compressor wheel under real operating conditions.

Lubrication of all kinds of highly stressed sliding surfaces, especially at low slip speeds or with oscillating movements Surface separation of temperature-stressed threaded connections For stainless-steel connections Advantages and benefits Broad field of application Good wear and corrosion protection Prevents burning-on and cold welding Good pressure absorption capacity No classification marks according to (EG) No. 1272/2008 Prolonged lubrication effect Metal-free For best adhesion, clean contamination and other lubricants from thread and slide surfaces. Best way is to clean mechanically first (for example, with a wire brush) and then with OKS 2610/OKS 2611 universal cleaning agent. Use a brush, spatula or similar to apply evenly a suitable quantity of paste to the head or nut contact surface and to the thread. The paste also acts as a sealant against spray water and condensate. Do not use paste instead of grease and mix only with suitable lubricants.

AMROC Color-Primed is the product version used for customized finish painting at the construction site. The product AMROC Color-Primed is ideally suited for applying the finished paint coat to the facade at the construction site. The front facing side and edges are primed in RAL 9010 (white) and the rear facing side is finish coated in RAL 7035 (light grey). The finish coat that is applied at the construction site creates vapor diffusion equilibrium between the front and rear facing sides. The factory applied primer does not yet completely seal the front facing side. The finish coat must be a paint-manufacturer-approved paint that is weather proof and alkaline stable. We recommend Amphibolin ELF made by Caparol for this purpose. AMROC Color-Primed is also suitable for: Flooring for wet spaces to be surface treated with ceramic materials, or similar Walls in wet spaces that will be surface treated with ceramic materials.

high resistance to moisture can be treated with ceramic materials

Our all-ceramic bearings are characterised by their high corrosion resistance to seawater and various chemicals. They are therefore used, for example, in the chemical industry, in the food and beverage industry, in shipping and in chlorine systems. We can manufacture our full ceramic ball bearings with rings and balls made of zirconium oxide (ZrO2) or silicon nitride (Si3N4), depending on the application. They are available with full balls or with cages made of PEEK or PTFE. The runout accuracies common with precision steel bearings cannot be achieved with all-ceramic bearings, so speed values have to be reduced. Ceramic materials are harder than steel, but also more brittle. Silicon nitride in particular has a low elongation at break and tends to break under tensile stress without prior plastic deformation. We take this into account when selecting the optimum bearing solution for your specific requirements.

We offer a line of ceramic bearings upone request. are made of ceramic in rolling elements and rings, and are characterised by a particularly large pressure range and temperature range of -250°C to +1000°C Bearings are current insulated no lubrication required
