Deep Groove Ball Bearings SKF 6403

The SKF 6403 deep groove ball bearing is an open, single-row rolling bearing measuring 17 × 62 × 17 mm, designed for radial and axial loads.

The SKF 6403 deep groove ball bearing is characterised by its large outer diameter in relation to the bore. As a single-row rolling bearing made from standard bearing steel (100Cr6), this design accommodates both radial and axial forces in both directions. The open design, without integrated sealing washers, allows unobstructed access of lubricant directly to the raceways. The outer ring is designed without a flange or groove, which facilitates cylindrical mounting in precisely fitted housing bores.

What design requirements does the SKF 6403 deep groove ball bearing meet?

Design engineers primarily use this design when a robust bearing arrangement with high load-carrying capacity is required for a shaft diameter of 17 mm. With an outer diameter of 62 mm and a width of 17 mm, the 64 series represents a particularly robust design. Relevant areas of application include general mechanical engineering and industrial drives, where the rolling bearing operates within a sealed housing and is lubricated from the outside.

What are the characteristics of the open design with standard bearing clearance?

The design without sealing washers avoids additional friction, as there are no sealing lips in contact with the bearing rings. The bearing is specified for a temperature range of -20 to +120 degrees Celsius and features standard radial clearance as well as tolerance class P0/PN (ABEC 1). A sheet steel cage guides the rolling elements evenly between the inner and outer rings and maintains the correct spacing between them during operation.
