312-Z Bearing Product Overview & Core Advantages
The 312-Z is a single row deep groove ball bearing designed for outstanding performance in demanding applications. Engineered with precision and reliability in mind, it excels at handling primarily radial loads and offers a compact, robust solution. Its key advantages include high operational reliability, low maintenance requirements due to its shielded design and pre-lubrication, and suitability for high-speed operation. This bearing is an ideal choice for applications requiring consistent performance and long service life.
312-Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| 312 | Basic Bearing Number | Defines the standard boundary dimensions: 60 mm bore, 130 mm outside diameter, 31 mm width. |
| -Z | Shield Designation | Indicates the bearing is fitted with a non-contact shield on one side. This provides effective protection against contaminants while minimizing friction and allowing for higher limiting speeds compared to contact seals. |
312-Z Bearing Structural Features & Performance Benefits
Optimized Deep Groove Raceway: The geometry of the raceways is designed for smooth operation and efficient handling of radial loads, contributing to low noise and vibration levels.
Nylon Cage (Polyamide): The use of a Nylon cage offers several performance benefits, including reduced weight, excellent sliding properties, and quiet operation. It is particularly advantageous in high-speed applications.
Shielded Protection: The Z-shield effectively prevents the ingress of solid contaminants and retains the lubricant, significantly extending the bearing's service life and enabling a maintenance-free design under normal operating conditions.
Pre-lubricated with Grease: Filled with a high-quality grease, the bearing is ready for immediate use, simplifying installation and ensuring optimal performance from the start within its specified temperature range of -30°C to 120°C.
312-Z Bearing Typical Application Areas
The 312-Z bearing is versatile and finds use in a wide array of industrial machinery and equipment, including:
- Electric Motors
- Gearboxes and Transmission Systems
- Industrial Pumps and Fans
- Material Handling Conveyors
- Agricultural Machinery
