1317KC3 Bearing Product Overview & Core Advantages
The 1317KC3 is a metric double row angular contact ball bearing engineered for demanding applications requiring high radial load capacity and precision. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing delivers exceptional rigidity and stability. Its open design allows for customized lubrication solutions, while the C3 radial internal clearance makes it suitable for applications with thermal expansion or heavy loads. Manufactured from chrome steel with a stainless steel cage, it offers reliable performance in a wide temperature range from -30°C to 110°C.
1317KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1317 | Standard bearing series designation indicating core dimensions: 85mm bore, 180mm OD, 41mm width. |
| K | Indicates a tapered bore with 1:12 ratio for precise interference fit on tapered shafts. |
| C3 | Specifies greater radial internal clearance than normal, suitable for applications with thermal expansion or where fit conditions create reduced internal clearance. |
1317KC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing construction provides superior stiffness and enables the bearing to support significant radial loads (dynamic: 21,938 lbf, static: 8,550 lbf). The optimized raceway and ball geometry ensure stable operation under combined loading conditions.
Precision Tapered Bore: The 1:12 tapered bore ensures a secure, interference fit on matching tapered shafts, eliminating creep and maintaining precise alignment for high-speed applications (limiting speed: 4,800 rpm).
Advanced Material Selection: Rings and balls made from high-grade chrome steel provide excellent wear resistance and fatigue life. The stainless steel cage offers high strength and corrosion resistance, contributing to reliable performance.
Operational Flexibility: The open seal type allows for the application of specific lubricants tailored to operational needs, while the C3 clearance accommodates thermal expansion in demanding environments.
