61806/C4 Bearing Product Overview & Core Advantages
The 61806/C4 is a metric single row deep groove ball bearing engineered for high-performance applications requiring precision and reliability. This bearing is characterized by its ability to primarily handle radial loads efficiently. Its compact design, with a 7 mm width, makes it an ideal solution for space-constrained assemblies. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent operational accuracy. A key feature is its C4 radial internal clearance, which is wider than normal, making it particularly suitable for applications involving thermal expansion or where shaft and housing fits may lead to a reduction in operational clearance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61806 | Standard designation for a single row deep groove ball bearing with a 30 mm bore, 42 mm OD, and 7 mm width. |
| /C4 | Indicates a greater than normal radial internal clearance. This is critical for applications with significant temperature gradients or specific mounting conditions. |
61806/C4 Bearing Structural Features & Performance Benefits
