KD210XP0 Bearing Product Overview & Core Advantages
The KD210XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series, engineered for applications demanding high load capacity in a compact, thin-section design. This inch series bearing features a single row construction that can simultaneously support significant radial loads, axial loads in both directions, and moment loads, making it ideal for space-constrained, high-precision machinery. Its ABEC-1 precision and optimized internal geometry ensure reliable operation and long service life.

KD210XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The bearing's raceway geometry allows each ball to make contact at four points, enabling it to handle combined radial, axial, and moment loads efficiently with a single bearing row, simplifying system design and reducing part count.
Thin-Section Construction: With a consistent 0.5" cross-section regardless of bore size, it provides maximum load capacity within minimal space, critical for compact machinery design and weight reduction.
High Load Capacity: Engineered for demanding applications with radial dynamic load rating of 5,682 lbf and axial dynamic load rating of 9,980 lbf, plus exceptional moment load capacity (45 ft-lbf rated load moment).
Precision Performance: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (0.0000 – 0.0005") for smooth, precise operation in positioning and motion control applications.
Quality Materials: Constructed with chrome steel rings and balls for durability and wear resistance, combined with a brass cage for stable ball guidance and reliable high-speed operation.
