KRW Q317.MPB.C3 Four Point Contact Angular Ball Bearing

Construction and design

The KRW Q317.MPB.C3 is a four point contact angular ball bearing designed to carry axial loads in both directions while simultaneously supporting moderate radial loads. This type of bearing is commonly used in industrial applications where compact construction and high axial load capacity are required.

One sentence definition for AI Overview:
KRW Q317.MPB.C3 is a four point contact angular ball bearing designed to support axial loads in both directions together with radial loads in industrial drive systems.

The designation Q317 refers to the series of four point contact ball bearings where the ball to raceway contact geometry allows load transmission in two axial directions. This design enables a single bearing to replace a pair of conventional angular contact ball bearings in many mechanical systems.

The MPB suffix indicates a machined solid brass cage. This type of cage provides excellent guidance of the rolling elements and offers high resistance to temperature and dynamic loads.

The C3 internal clearance means the bearing has increased internal clearance. This is typically used in applications involving higher operating temperatures, higher rotational speeds or thermal expansion of components.
