  • » Four-point contact ball bearings – two in one

    2015-6-25u2002·u2002Four-point contact ball bearings (QJ bearings) are a specific type of angular contact ball bearings. In many applications one QJ bearing is an interesting alternative to a matched set of single-row angular contact ball bearings. Indeed, its space-saving design, the speed capabilities and the load carrying capacity are remarkable.

  • Four-point contact ball bearings

    Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported . The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two ...

  • A Design Method of Thin-Walled and Four-Point Contact

    2015-5-5u2002·u2002Abstract. Thin-walled and four-point contact ball bearings are key elements for industrial robots, since they play a critical role in the action accuracy, running stability and flexibility, and service life for the main engine of robots.

  • Design considerations

    Design considerations. Four-point contact ball bearings are often used as entirely thrust bearings, together with a radial bearing. When used in this way, the four-point contact ball bearing should be mounted with radial clearance in the housing ( fig. 1 ). Therefore, it should not be clamped axially, but a small gap should be maintained ...

  • Designation system

    Designation system. The designations of most SKF rolling bearings follow a system that may consist of a basic designation with or without one or more prefixes and/or suffixes ( Basic bearing designation system ). An example and the applicable options for four-point contact ball bearings are given below.
