Special profiles for oleohydraulics - Import export

Each bearing is designed around the application it is used in and sometimes that include a profile on the inner or outer ring. We have an array of profiles that we can use on our bearings, including common ones listed below or something completely unique to your application. In collaboration with our application engineers, we will work with you to ensure the right profile, tolerances, material, surface finish, and even the harmonics of the profile are fine-tuned to ensure quite operation, even at high speeds.

Not all extruded profiles are required to be circular in shape! Whether it is a seamless or porthole hollow-profile, at ALUnna, we have a multitude of possibilities. Simple profiles, such as a solid profile or an angle profile, are also available. On some profiles we may have the possibility to further improve the dimensional tolerances by adding a subsequent drawing step to achieve final dimensions. In addition to round tube, shaped, square or rectangular tubes in both medium strength and high-strength alloys can be produced.

Sigma profiles provide an easy and versatile installation opportunity thanks to its channel structure. Sigma profiles are used in many areas such as conveyor, chassis, table, cabinet, cnc, area closure and are a special material that meets the needs of the industry. The reasons why aluminum is preferred in applications: Aluminum is lightweight. It weighs only a third of the same volume of steel. Aluminum is resistant to weather conditions, foodstuffs and many liquids and gases used in everyday life. It has an attractive appearance for both interior and exterior use and this appearance can be maintained for a long time. The strength of various aluminum alloys is equal to or higher than the strength of normal structural steel. Aluminum is an elastic material. Therefore, it is resistant to sudden impacts. In addition, its strength does not decrease at low temperatures, as is the case with steels. It is an easy metal to process. It conducts heat and electricity as well as copper.
