1317-K C/4 Bearing Product Overview & Core Advantages
The 1317-K C/4 is a metric double row angular contact ball bearing engineered for demanding industrial applications requiring high precision and reliability. Featuring a tapered bore (1:12) and open construction, this bearing is designed to accommodate combined radial and axial loads simultaneously. Its double row design provides high rigidity and exceptional load-carrying capacity in a compact envelope. Manufactured from premium chrome steel components and featuring a stainless steel cage, it delivers consistent performance across a wide temperature range from -30°C to 110°C. Pre-lubricated for immediate use, it is an ideal solution for high-speed machinery up to 4,800 rpm.
1317-K C/4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 1317-K | Basic bearing designation with tapered bore | Indicates specific bearing dimensions (85mm bore, 180mm OD) and conical bore for precise mounting |
| C | Radial internal clearance designation | Specifies CN clearance group - normal clearance for most industrial applications |
| /4 | Lubrication suffix | Indicates factory-applied high-performance grease for immediate operation |
1317-K C/4 Bearing Structural Features & Performance Benefits
Double Row Design: The two rows of balls arranged at optimal contact angles provide high rigidity and superior moment load capacity compared to single row bearings, making it ideal for applications requiring precise shaft positioning.
Tapered Bore & Mounting: The 1:12 taper enables precise interference fit when mounted on adapter sleeves or tapered shafts, ensuring secure seating and eliminating fretting corrosion.
Premium Material Construction: Chrome steel rings and balls combined with a corrosion-resistant stainless steel cage deliver extended service life and reliable operation in challenging environments.
Optimized Load Capacity: With a dynamic load rating of 21,938 lbf and static load rating of 8,550 lbf, this bearing handles significant combined loads while maintaining precision.
High-Speed Capability: The precision-ground components and optimized cage design enable operation at limiting speeds up to 4,800 rpm, suitable for various industrial machinery.
