Description
Super-precision bearings are ideal for machine tools and other precision applications such as rolling mills, racing cars and marine vessels. The bearings also minimize noise, vibration and heat generation.
Angular contact ball bearings
Available in a wide selection of designs and materials – including four ISO dimension series in numerous executions – these bearings can be incorporated into virtually every application where precision bearings are required.
Cylindrical roller bearings
Super-precision cylindrical roller bearings are characterized by:
High speed capability
High radial load carrying capacity
High rigidity
Low friction
Low cross-sectional height
Double direction angular contact thrust ball bearings
Enable location of spindle shafts axially in both directions. Available in two different series and intended for mounting with corresponding cylindrical roller bearings in the same housing bore, for simplified machining of the housing bore.
Axial-radial cylindrical roller bearings
Super-precision axial-radial cylindrical roller bearings are commonly used to support rotary tables, indexing heads and multi-spindle heads on machining centres. SKF manufactures super-precision axial-radial cylindrical roller bearings for shaft diameters from 80 to 850 mm. Their internal design, together with close tolerance manufacturing processes, enables these bearings to attain radial run-out better than, and axial run-out close to, P4 tolerance class.
Precision lock nuts
Simple to mount, with either locking pins or axial locking screws, designed to locate bearings and other components in applications where high precision and reliable locking are required.
Bearing Gauges
Conventional measuring methods and instruments are not always suitable for checking tapered seats or measuring the inside or outside envelope diameter of the roller set of a cylindrical roller bearing in precision applications. Therefore, SKF has developed an assortment of gauges specially designed to take the accurate measurements necessary when mounting cylindrical roller bearings with a tapered bore. These gauges are also useful for other than precision applications.
