Machine tools and other precision applications require superior bearing performance. Extended speed capability, a high degree of running accuracy, high system rigidity, low heat generation, as well as low noise and vibration levels are just some of the challenges.
Rolling bearings for general industrial applications can only partly fulfill these requirements. Therefore, SKF manufactures a comprehensive assortment of super-precision bearings.
SKF super-precision bearings help original equipment manufacturers and end users to further optimize performance parameters of their equipment and applications. The benefits differ depending on the bearing series and applications but include high speed and load carrying ability, long bearing service life, long maintenance intervals and low energy consumption.
Typical applications for super-precision bearings are:
- metal cutting and woodworking machinery spindles
- other machine spindles (e.g. balancing machines)
- high speed rolling mills
- printing machinery
- precision ball screws
- live centres
- high speed turbochargers
- vacuum pumps
- racing cars
- boat gyrostabilizers
- machine components for the semiconductor industry
Angular Contact Ball Bearings
SKF manufactures super-precision angular contact ball bearings for shaft diameters from 6 to 360 mm. Application requirements vary, and as a result, the SKF assortment of super-precision angular contact ball bearings includes four ISO dimension series, in numerous executions. The wide selection of designs and variants enables them to be incorporated into virtually every machine tool application as well as other applications where precision bearings are required.
SKF double row cam rollers are based on double row angular contact ball bearings in the 32 dimension series and have a 30° contact angle. They are supplied greased and capped with either a sheet steel shield, on boths sides, that extends into a recess on the innner ring (suffix -2Z) or an RS contact seal on both sides (suffix -2RS1).
