K34020AR0 Bearing Product Overview & Core Advantages
The K34020AR0 is a metric thin-section angular contact ball bearing from the Reali-Slim series, engineered for applications demanding high precision and space optimization. Its single-row design with a 30° contact angle enables it to efficiently support combined loads (simultaneous radial and axial loads) in one direction. Manufactured to ABEC-1 precision standards, this bearing offers reliable performance in compact envelopes, making it ideal for high-rigidity systems where weight and cross-section are critical constraints.
K34020AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K34020 | Basic bearing designation indicating thin-section metric series with 340mm bore, 380mm OD, and 20mm width |
| A | Angular contact design with 30° contact angle |
| R0 | Standard radial internal clearance (0.0000 – 0.0005") |
K34020AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: With only 20mm width and minimal cross-section, this bearing enables compact machine designs while maintaining high rigidity through precision-ground raceways and optimized ball complement.
Superior Load Capacity: The 30° contact angle provides excellent axial load capacity in one direction (19,671 lbf static axial rating) while maintaining substantial radial load capacity (21,657 lbf static radial rating), making it suitable for combined loading applications.
Precision Engineering: Manufactured to ABEC-1 tolerance class with chrome steel rings and balls, ensuring consistent performance and extended service life in precision applications.
Enhanced Stability: The brass cage maintains proper ball spacing and alignment, contributing to smooth operation and reduced vibration at moderate speeds.
Wide Temperature Compatibility: Operating range of -30°C to 110°C accommodates various industrial environments when properly lubricated.
