6312-2Z/LHT55 Bearing Product Overview & Core Advantages
The 6312-2Z is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Its key advantage lies in its ability to efficiently handle radial loads while offering a compact and cost-effective solution. The inclusion of shielded seals (2Z) provides effective protection against contaminant ingress, enhancing bearing service life and reliability. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing ensures consistent performance and is an excellent choice for applications requiring dependable operation under standard conditions.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6312 | Basic bearing series and size designation (60mm bore, 130mm OD, 31mm width). |
| 2Z | Bearing is fitted with shielded seals on both sides. This provides good protection against contaminants while allowing for relatively high-speed operation. |
| /LHT55 | The bearing is pre-lubricated with LHT55 high-performance grease. This synthetic grease offers a wide temperature range (-30°C to +120°C), excellent oxidation stability, and long-term lubrication, contributing to a maintenance-free design. |
6312-2Z/LHT55 Bearing Structural Features & Performance Benefits
- Optimized for Radial Loads: The single row deep groove raceway geometry is precision-engineered to carry significant radial dynamic load ratings (18,412 lbf), making it a workhorse for many mechanical systems.
- Shielded Protection: The 2Z shields act as non-contact physical barriers, effectively excluding larger particulate contaminants. This design helps retain the factory-applied LHT55 grease and maintains a clean internal environment, which is critical for achieving the specified limiting speed of 5,300 rpm.
- Pre-lubricated for Longevity: Pre-filled with LHT55 grease, the bearing is ready for immediate installation and offers extended service life without the need for re-lubrication, reducing maintenance requirements.
- Robust Construction: All components, including rings, balls, and cage, are manufactured from high-grade chrome steel, ensuring high strength, durability, and consistent performance.
