K34020XP0 Bearing Product Overview & Core Advantages
The K34020XP0 is a metric thin-section four-point contact ball bearing engineered for applications requiring high precision and compact design. As a Reali-Slim series bearing, it features an exceptionally thin cross-section relative to its bore diameter, making it ideal for space-constrained installations. Its four-point contact design enables it to simultaneously support combined radial and axial loads from any direction, providing exceptional rigidity and moment load capacity in a single-row configuration. Manufactured to ABEC-1 precision standards with chrome steel components, this bearing delivers reliable performance in precision motion systems.

K34020XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The unique raceway geometry allows the bearing to handle combined loads efficiently, with exceptional moment load capacity (rated at 5812 ft-lbf) and bidirectional axial loads.
Thin-Section Construction: With a 20 mm width and large 340 mm bore diameter, this bearing provides maximum space savings while maintaining structural integrity.
Premium Material Selection: Chrome steel rings and balls combined with a brass cage ensure dimensional stability, corrosion resistance, and reliable operation across the specified temperature range (-30°C to 110°C).
Precision Engineering: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (0.0000 – 0.0005") for smooth, precise operation in demanding applications.
High Load Capacity: Delivers impressive dynamic load ratings (radial: 9674 lbf, axial: 15771 lbf) and static load ratings (radial: 17954 lbf, axial: 44886 lbf) despite its thin-section design.
