Product description of SKF Bearing 52209

SKF Bearing 52209, it belongs to SKF Bearing > Rolling bearings > Ball bearings > Thrust ball bearings > Double direction.

SKF thrust ball bearings are manufactured as single direction (fig. 1) or double direction thrust ball bearings. They are designed to accommodate axial loads only and must not be subjected to any radial load.

In addition to the bearings presented in this section, SKF supplies thrust ball bearings for special application requirements. This assortment includes bearings with Solid Oil and NoWear coated bearings.

consist of one shaft washer, two housing washers and two ball and cage assemblies. The housing washers and ball and cage assemblies of double direction bearings are identical to those used in single direction bearings.

can accommodate axial loads and locate a shaft axially, in both directions.

Thrust ball bearings are classified into those with flat seats or aligning seats depending on the shape of the outer ring seat (housing washer). They can sustain axial loads but no radial loads. For Single-Direction Thrust Ball Bearings, pressed steel cages and machined brass cages are usually used The cages in Double- Direction Thrust Ball Bearings are the same as those in Single-Direction Thrust Ball Bearings of the same diameter series.

Features
Available in two designs: single direction and double direction. To accommodate initial misalignments in an assembly both designs are available with spherical aligning seats or aligning seat washers. High quality steel-ultra clean steel to extend bearing life by up to 80%. Advanced Grease Technology — NSK lubricants that can extend grease life and performance.

High Grade Balls — Quiet and smooth operation even at high speed.

Optional seating rings take initial misalignment.

SKF Bearing 52209, SKF double direction angular contact thrust ball bearings are designed to locate spindle shafts axially in both directions. These bearings are intended for mounting in combination with cylindrical roller bearings in the NN 30 K or N 10 K series in the same housing bore. This bearing combination simplifies machining of the housing bore.

SKF Bearing 52209,Double direction angular contact thrust ball bearings are manufactured with the same nominal bore size and outside diameter as corresponding cylindrical roller bearings. However, the outside diameter tolerance of the housing washers, combined with the housing bore diameter and geometric tolerances recommended for super-precision cylindrical roller bearings under light to normal load and rotating inner ring load (Seat tolerances for standard conditions) will result in an appropriate radial clearance in the housing bore. This clearance is sufficient to prevent radial loads from acting on the thrust bearing provided that its outer ring is not axially clamped in the housing.
