1217 K Bearing Product Overview & Core Advantages
The 1217 K is a double row angular contact ball bearing designed for applications requiring high radial load capacity and compact design. This precision bearing features a high-rigidity double row construction, enabling it to handle significant combined loads. Manufactured with chrome steel rings and balls, and a lightweight nylon cage, it offers reliable performance in demanding industrial environments. Its open design allows for versatile lubrication options, making it suitable for various operating conditions.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1217 | Standard bearing series designation, indicating specific bearing dimensions (85mm bore, 150mm OD, 28mm width) |
| K | Indicates a tapered bore (conical bore) with a taper of 1:12, facilitating precise mounting and dismounting on adapter sleeves or withdrawal sleeves |
1217 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball arrangement provides superior high rigidity, enabling the bearing to support substantial radial dynamic load ratings of 10,980 lbf while maintaining dimensional stability under heavy loads.
- Optimized Cage Design: The nylon cage ensures smooth operation, reduces friction, and contributes to the bearing's suitability as a high-speed bearing with a limiting speed of 5,600 rpm.
- Tapered Bore Advantage: The K-suffix tapered bore allows for precise axial positioning and secure mounting on shafts, enhancing operational reliability and simplifying maintenance.
- Material Excellence: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and durability across a wide temperature range from -30°C to 110°C.
