W 61807-2Z Bearing Product Overview & Core Advantages
The 61807-2Z is a single row deep groove ball bearing designed for high-performance applications requiring compact design and reliable operation. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle radial loads efficiently while accommodating moderate axial loads in both directions. The integral shielded design (2Z) and pre-lubrication with grease ensure long service life and maintenance-free operation, making it ideal for applications demanding high reliability and cleanliness.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 61807 | Bearing Series & Size | Denotes a metric, extra-thin section deep groove ball bearing with a 35mm bore, 47mm OD, and 7mm width. |
| 2Z | Seal Type | Signifies bearings with shields on both sides. This provides effective protection against contamination while allowing for higher limiting speeds compared to contact seals. |
