K08020AR0 Bearing Product Overview & Core Advantages
The K08020AR0 is a single row angular contact ball bearing engineered for applications requiring high precision and reliable performance under combined loads. Its design excels at simultaneously handling significant radial loads and unidirectional axial loads, making it an ideal choice for compact, space-constrained assemblies. Manufactured to ABEC-1 tolerance standards, this bearing ensures consistent operation and is pre-lubricated for immediate use, offering a robust solution for demanding industrial environments.
K08020AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K08020 | Bearing series designation indicating a metric Thin Section bearing with an 80mm bore, 120mm outside diameter, and 20mm width. |
| A | Signifies a 30° contact angle, optimized for carrying high axial loads in one direction. |
| R0 | Specifies a standard radial internal clearance (0.0000 – 0.0005") for general operating conditions. |
K08020AR0 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its specific construction. The single row design with a 30° contact angle provides excellent resistance to combined loads. The use of a brass cage ensures stability and guidance of the precision chrome steel balls at higher rotational speeds, contributing to smooth operation. The open seal type allows for optimal heat dissipation and is suitable for applications where external sealing is provided. With a radial dynamic load rating of 3785 lbf and a high axial static load rating of 8201 lbf, it delivers reliable performance and high rigidity in a slim cross-section.
