In textile sector, cylinders which are used for drying wet fabric, are heated with steam. High temperature Rotating Joints are used to transfer steam from stationary supply pipes to rotating cylinders. Long life of high temperature are guaranteed with the advantage of special alloy carbon graphite seal ring and graphite ring.

In continuous casting process hot steel is cooled with rolls. These rolls are cooled with water. While hot steel passes, these rolls rotate and CCM Rotating Joints are used to transfer water from stationary supply lines to rotating rolls. In addition, withdrawal and straightening units are cooled with water by using CCM rotary joint in the shaft mounted rotating joints.

General water and Hydraulic Rotating Joints equipped with silicon carbide seals are used safely for many years in the packaging, printing, plastic and rubber industry.

In oil and gas industries general oil rotary joint with faces silicon carbide or Tungsten carbile with metallic Carbon are applied. These series are easily replaceable and reparable on site.

Air and Hydraulic Rotating Unions, maintenance free, mini housing design with life lubricated bearings is used on the air operated shafts and brake& clutch units.

As an innovator in applied engineering, John Crane is well equipped to address the unique and challenging requirements of the pharmaceutical industry. We engineer our products to meet the industry’s safety and reliability standards — as well as local environmental regulations — so that our chemical processing customers can increase their uptime and lower their license fees. From clean-in-place components to batch documentation and certification of material integrity, John Crane provides pharmaceutical processing companies with the engineered components and services they need.

Sealing systems featuring maximum operational reliability, convenient maintenance and low leakage rates with necessary environmental protective measures are standard requirements in modern power stations. The product range includes mechanical seals and supply systems for auxiliary and secondary pumps, boiler circulation pumps and feedwater pumps as well as mechanical seals and carbon floating ring seals for turbines, compressors and fans.

In this Industry chemically inert materials are often used for the mechanical seals produced and, depending on the specific sector’s use, alumina, PTFE, Kalrezor FEP can be used. In this way, Rota-Tech answers all the productive standards that underlie the production of mechanical seals for the chemical sector in complete conformity of the regulations in force.

When the operation of leak-free rotating equipment is under consideration, a cost-effective solution to gland sealing must be considered and Rota-Tech has sealing technology solutions, with proven-reliability, for each stage of the process.

Components from carburetors to gears, and valve stems require flexible machining centres. Large presses for auto stamp bodies or frames use air or hydraulic clutches with rotating unions. Welding equipment including robotic, TIG welders employ rotating unions for air clamping devices.

Rotating Unions may be used to transmit coolant, cutting oil, MQL, pressurized air with or without bearingsupported configuration. Our seal technologies include Pop-Off, Multi-media, AutoSense and a variety of other advanced technologies for all applications.Besides coolant delivery, Rota-tech unions or joints are used for chucking, tool sensing, rotary index table and other machine tool applications. The selections in the website represent a small range of standard products.

Rotary union is used in printing industries (flexo printing machine) for cooling of cylinder drum where printing papers or sheets are passed which are hot for drying of ink colour. General water rotary joint with media used for cooling are water and faces silicon carbide with carbon in combination.

High temperature rotary joint with steam as media are passed having Carbon graphite and carbon seal rings for leakage prevention are used in corrugators.

Many seals employed in Food & Beverage applications should be hygienically designed. Rota-Tech designs conform to Hygienic with non-clogging seal profiles. These seals reduce the probability of micro-organism growth and cross-batch contamination. We also avoid using materials that may affect the quality of the finished product, using FDAcertified materials as standard.

Mining and Quarry applications are dominantly abrasive slurry applications. Mechanical seals generally fail very quickly. We Rota-Tech provides best suited Slurry Type Mechanical Seals varying viscosity fluids along with solids perfectly suited for mining applications.Rota-Tech offers complete line of slurry mechanical seals to satisfy most slurry and liquid hydro transport applications in a wide range of industries.
