6315-2Z/DTWT Bearing Product Overview & Core Advantages
The 6315-2Z is a single row deep groove ball bearing featuring integral shielded protection. Engineered for high radial load capacity and reliable performance in a wide range of industrial applications, this metric bearing offers a robust solution where space is limited. Its ABEC 1 (ISO P0) tolerance class ensures consistent operational accuracy, making it a cost-effective choice for general machinery requiring dependable rotation and moderate speed capabilities.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6315 | Standard series designation for a single row deep groove ball bearing with a 75 mm bore and 160 mm outside diameter. |
| 2Z | Indicates the bearing is shielded on both sides. These non-contact steel shields protect the internal components from large particulate contaminants while allowing for high-speed operation with minimal friction increase. |
6315-2Z/DTWT Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The deep groove raceway and single row construction are specifically designed to handle significant radial dynamic and static loads (25,403 lbf and 17,355 lbf respectively), providing stable support for rotating shafts.
Shielded Protection: The 2Z designation signifies steel shields pressed into both sides of the outer ring. This creates an effective barrier against dust and debris, extending bearing life without the added friction of contact seals, contributing to its limiting speed of 4,300 rpm.
Precision & Consistency: Manufactured to ABEC 1 (ISO P0) tolerance standards with a standard CN radial internal clearance, this bearing ensures smooth and reliable operation under normal load and speed conditions.
Material Integrity: All core components, including rings, balls, and cage, are constructed from high-carbon chromium steel, offering excellent hardness, wear resistance, and durability for long-term performance.
6315-2Z/DTWT Bearing Typical Application Areas
The 6315-2Z is versatile and is commonly specified in:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring robust, shielded bearings
