KD210AR0 Bearing Product Overview & Core Advantages
The KD210AR0 is a thin-section angular contact ball bearing designed for applications requiring high precision and space optimization. As part of the Reali-Slim Open Bearings series with a 1-inch cross-section, this single-row bearing excels in handling combined loads through its specific 30° contact angle, effectively managing both radial and axial forces. Manufactured to ABEC-1 precision standards with chrome steel components and brass cage construction, it delivers reliable performance in compact assemblies where weight and space are critical constraints.
KD210AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KD | Kaydon Reali-Slim bearing series identifier |
| 210 | Bore diameter code for 21-inch bore size |
| A | Angular contact design with 30° contact angle |
| R | Radial internal clearance specification |
| 0 | Open (unsealed) construction variant |
KD210AR0 Bearing Structural Features & Performance Benefits
The KD210AR0's engineering delivers distinct performance advantages through its optimized construction. The single-row angular contact design with 30° contact angle provides exceptional axial load capacity (12,086 lbf static) while maintaining substantial radial load rating (4,472 lbf dynamic). The brass cage ensures stable ball guidance and smooth operation across the temperature range (-30°C to 110°C). With precision-ground chrome steel rings and balls, the bearing achieves ABEC-1 tolerance class accuracy and minimal radial internal clearance (0.0000-0.0005"), enabling precise positioning in demanding applications. The open design facilitates custom lubrication schemes for optimal performance in specific operating conditions.
