Edge or race-guided plastics cage for roller bearings

In a raceway-guided or flange-guided cage made of plastic for roller bearings, webs (18) between side rings (14) and (16) are specially designed to prevent foreign particles present in the lubricant from damaging contact surfaces (S) of rollers (R). For this purpose, guide surfaces (26) are provided...

More Information
Summary:In a raceway-guided or flange-guided cage made of plastic for roller bearings, webs (18) between side rings (14) and (16) are specially designed to prevent foreign particles present in the lubricant from damaging contact surfaces (S) of rollers (R). For this purpose, guide surfaces (26) are provided only at edges of rollers (R). Intermediate web side surfaces (30, 32) are set back from contact surface (S) by a wider gap (G). Retaining projections (40) are also separated by a gap (G1) from contact surface (S) in the axial center, the point of greatest flexiblity for the snapping-in of the rollers.
