1210 KC3 Bearing Product Overview & Core Advantages
The 1210 KC3 is a metric double row angular contact ball bearing engineered for applications requiring high radial load capacity and rigid shaft support. Featuring a tapered bore design (1:12 ratio), this precision bearing delivers exceptional stability and alignment capabilities. Its C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used. The bearing comes pre-lubricated and operates effectively within a temperature range of -30°C to 110°C, making it a high-performance solution for demanding industrial environments.
1210 KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1210 | Standard bearing designation: 50mm bore, 90mm OD, 20mm width |
| K | Tapered bore with 1:12 ratio for precise mounting and dismounting |
| C3 | Greater than normal radial internal clearance for thermal expansion compensation |
1210 KC3 Bearing Structural Features & Performance Benefits
Double Row Design: The two-row ball arrangement provides high rigidity and superior radial load capacity compared to single row bearings, making it ideal for applications requiring stable rotational accuracy.
Tapered Bore Advantage: The 1:12 tapered bore allows for precise axial positioning and secure mounting on tapered shafts or adapter sleeves, ensuring optimal performance and easy maintenance.
Enhanced Load Capacity: With a dynamic load rating of 5962 lbf and static load rating of 2059 lbf, this bearing handles significant radial loads while maintaining operational reliability.
Optimized Cage Design: The nylon cage contributes to smooth operation at limiting speeds up to 10,000 rpm, reducing friction and enabling high-speed performance.
Pre-lubricated Construction: Factory-applied lubrication ensures immediate operation and reduces maintenance requirements, while the open design allows for relubrication if needed.
