KF055XP0 Bearing Product Overview & Core Advantages
The KF055XP0 is a Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series, designed for applications demanding compact cross-sections and high load capacity. This thin section bearing features a single row construction and an open design, enabling it to simultaneously support significant combined radial and axial loads from any direction. Manufactured to ABEC-1 precision tolerances, it delivers reliable performance in space-constrained, high-rigidity systems.

KF055XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The raceway geometry allows the bearing to handle combined loads efficiently. A single bearing can replace a complex pair of angular contact bearings, simplifying design and saving space.
High Load Capacity: Engineered with a brass cage and chrome steel components, it offers a high dynamic load rating of 5415 lbf (radial) and 8200 lbf (axial), along with a substantial static load rating for demanding applications.
Precision & Rigidity: Built to ABEC-1 tolerance standards with a controlled radial internal clearance, it ensures smooth, precise operation and contributes to system stability and accuracy.
Compact & Lightweight: As a thin section bearing with a width of only 0.75", it is ideal for lightweighting designs without sacrificing performance, weighing just 2.5 lbs.
KF055XP0 Bearing Typical Application Areas
- Robotics: Rotary joints and actuators requiring high moment load capacity.
- Aerospace & Defense: Radar platforms, gimbals, and flight control systems.
- Medical Equipment: CT scanners and MRI machines where precision and reliability are critical.
- Industrial Automation: Rotary tables, indexing heads, and precision positioning stages.
- Semiconductor Manufacturing: Wafer handling robots and precision motion control systems.
