KD042XP0 Bearing Product Overview & Core Advantages
The KD042XP0 is a high-performance thin section bearing designed for applications requiring maximum space efficiency and precision. As a Four Point Contact ball bearing, it excels at simultaneously handling combined radial and axial loads from any direction, making it an ideal solution for compact, weight-sensitive designs. Manufactured to ABEC-1 precision standards, it delivers reliable performance in demanding industrial environments. Its open design allows for custom lubrication schemes, while the robust construction using Chrome Steel components ensures long service life and consistent operation.

KD042XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry enables the bearing to support radial loads, axial loads in both directions, and moment loads simultaneously, eliminating the need for multiple bearing arrangements and saving valuable space.
Thin Section Construction: With a consistent cross-section of 0.5" across all sizes in the series, the KD042XP0 provides maximum load capacity within minimal space, making it perfect for weight-critical applications.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore and OD tolerance: -0.0008" to 0"), ensuring smooth operation and precise positioning in automated systems.
Robust Material Selection: Chrome Steel rings and balls combined with a Brass cage provide excellent durability and reliable performance under the specified temperature range of -30°C to 110°C.
High Load Capacity: The bearing delivers impressive dynamic load ratings (radial: 2355 lbf, axial: 3600 lbf) and static load ratings (radial: 3190 lbf, axial: 7980 lbf) despite its slim profile.
