Rolling bearings
Ball bearings
Ball bearings use balls as a rolling element. They are characterized by a contact point between the balls and the raceways. Ball bearings can rotate very quickly but cannot carry heavy loads.
Roller bearings
Roller bearings use rollers as a rolling element, they are characterized by a contact line between the rollers and the raceways. This type of contact allows roller bearings to have a higher load coefficient than ball bearings of the same size; however the speed is lower than that of ball bearings due to the greater friction generated by the greater contact.
Needle roller bearings
Needle roller bearings are equipped with cylindrical rollers.
The modified roller / raceway profile avoids stress peaks to extend bearing service life.
Miniature bearings
Micro and miniature bearings are specially designed and manufactured for some industrial applications including the medical equipment and model making sector.
Precision bearings
Having high rolling accuracy, high speed characteristics and high system rigidity, precision bearings are ideal for machine tools and other precision applications such as rolling mills, racing cars and boats. They also help minimize noise, vibration and heat generation.
Supports
The self-aligning pillow blocks (units equipped with ball or roller bearings) are configurable inside housings (available in different shapes and materials) and can be completed with a sealing system. Depending on the application and operating conditions, it's possible to offer supports made of pressed sheet metal, cast iron, steel, polymer, stainless steel.
