6004-2RZ/LHT23 Bearing Product Overview & Core Advantages
The 6004-2RZ/LHT23 is a single row deep groove ball bearing engineered for high-performance applications requiring reliable operation under radial loads. Its sealed construction with the 2RZ designation provides robust protection against contamination, while the LHT23 high-performance grease enables stable operation across a wide temperature range. This bearing offers an optimal balance of high limiting speed, substantial load capacity, and long service life, making it a versatile and dependable component for demanding industrial environments.
6004-2RZ/LHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6004 | Standard bearing series designation indicating a metric, single row deep groove ball bearing with a 20mm bore, 42mm OD, and 12mm width. |
| 2RZ | Signifies non-contact seals on both sides. The "RZ" seal type provides effective protection against dust and moisture while maintaining low friction and enabling high rotational speeds. |
| LHT23 | Indicates the bearing is pre-lubricated with LHT23 grease, a lithium complex-based lubricant designed for a wide operating temperature range (-40°C to +140°C) and extended service intervals. |
6004-2RZ/LHT23 Bearing Structural Features & Performance Benefits
- Optimized Sealing: The non-contact 2RZ seals effectively exclude contaminants while minimizing friction and heat generation, contributing to the bearing's high limiting speed of 17,000 rpm.
- Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a dynamic load rating of 2113 lbf and a static load rating of 1135 lbf, ensuring reliable performance under significant radial stresses.
- Precision & Stability: Built to ABEC 1 | ISO P0 tolerance standards with CN radial internal clearance, this bearing provides consistent running accuracy and smooth operation essential for general industrial applications.
- Maintenance-Free Operation: The combination of integral seals and pre-applied LHT23 grease creates a sealed-for-life unit, eliminating the need for re-lubrication and reducing maintenance costs.
6004-2RZ/LHT23 Bearing Typical Application Areas
- Electric Motors: Ideal for small to medium-sized motors requiring sealed, high-speed bearings.
- Industrial Gearboxes: Suitable for auxiliary shafts and locations demanding reliable, pre-lubricated components.
- Material Handling Equipment: Used in conveyor rollers, pulleys, and other machinery where contamination resistance is critical.
- Agricultural Machinery: Applicable in various farm equipment components exposed to dusty environments.
- Ventilation Systems: Perfect for fans and blowers operating at moderate to high speeds.
