Linear guides offer precise positioning on paper cutter

Dean Palmer reports on how linear slides are being used on a paper slitting and rewinding machine to precisely position the knife and core   Read More


Bearings solve motion problems

Vee bearings are used to create accurate sliding systems in a variety of applications, especially applications where ball bushings or re-circulating ball carriages would be prone to dust, dirt and other foreign matter penetration, which would ruin their performance.  Read More


Bearing technology ups performance of food processing machines

New bearing technology is helping to reduce downtime and the total cost of ownership of a vegetable peeling machine.   Read More

Tom Shelley reports on why a maker of inspection trolleys found particular advantage in working with a blue chip quality supplier  Read More


Bearings guide giant optical telescope

The largest optical telescope in the Southern Hemisphere is using air bearings and a rotary table bearing to help it remain in one position rather than having to compensate for the earth's rotation. Dean Palmer reports   Read More


Design collaboration: identifying the real needs of the customer

By building closer working relationships with customers, preferably at the concept design stage, INA FAG says it is helping to add real value to design projects. Dean Palmer reports   Read More


Bearings adapt to the task

Tom Shelley reports on novel bearings that adjust themselves to take account of different load conditions and run unusually fast and cool in machine tool spindles  Read More


Polymer bush offers near zero wear

Dean Palmer takes a look at a new polymer compound for bearings and bushes that promises to reduce costs and improve the performance of industrial pumps  Read More


World's first thin-section turntable bearings

Customer demand for a more compact design of turntable bearing has prompted a bearings supplier to design a miniature unit that still offers the same performance and operating life, writes Dean Palmer  Read More


Durable ball rail can be mounted on uneven surfaces

Dean Palmer reports on a new ball rail system for handling and positioning tasks that offers high load capacity and can be mounted directly onto uneven surfaces and sheet metal   Read More


High precision three-stage bearing solves turbo problems
