61809-2RZ Bearing Product Overview & Core Advantages
The 61809-2RZ is a metric single row deep groove ball bearing designed for high-performance applications requiring compact design and reliable operation. This sealed bearing excels in handling radial loads with excellent precision, thanks to its P6 tolerance class. Its compact cross-section (7mm width) makes it ideal for space-constrained assemblies while maintaining robust load capacity. Pre-lubricated with grease and featuring integral seals, it offers maintenance-free operation and reliable performance across a wide temperature range.
61809-2RZ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 61809 | Deep groove ball bearing series with 45mm bore | Standard radial load bearing design |
| 2RZ | Non-contact rubber seals on both sides | Effective contamination protection with minimal friction |
61809-2RZ Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional control (bore: -0.01mm to 0), ensuring high running accuracy and consistent performance in precision applications.
Robust Load Capacity: Features chrome steel rings and balls with stainless steel cage, delivering a dynamic load rating of 1286 lbf and static load rating of 1124 lbf for reliable operation under significant radial stresses.
Sealed Protection: The 2RZ non-contact rubber seals provide excellent protection against contaminants while maintaining low friction, contributing to the high limiting speed of 12,000 rpm.
Maintenance-Free Operation: Factory-pre-lubricated with high-quality grease and sealed construction eliminates the need for relubrication, reducing maintenance costs and downtime.
