1319 KC3 Bearing Product Overview & Core Advantages
The 1319 KC3 is a metric double row angular contact ball bearing engineered for demanding industrial applications requiring high radial load capacity and precision operation. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing delivers exceptional rigidity and stability under heavy loads. Its open design, combined with a C3 radial internal clearance, makes it suitable for applications with thermal expansion considerations. Manufactured from high-grade chrome steel with a nylon cage, it offers reliable performance in a temperature range of -30° to 110°C, making it an ideal choice for high-reliability machinery.
1319 KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1319 | Standard bearing series designation indicating specific bearing dimensions (95mm bore, 200mm OD, 45mm width) |
| K | Indicates tapered bore with 1:12 taper ratio for precise mounting and adjustment |
| C3 | Specifies greater than normal radial internal clearance for applications with thermal expansion or where fit interference creates reduced clearance |
1319 KC3 Bearing Structural Features & Performance Benefits
Double Row Design for Enhanced Load Capacity: The double row ball bearing construction provides significantly higher radial load rating (29,925 lbf dynamic) compared to single row bearings, enabling support for heavier loads in compact envelope dimensions.
Precision Tapered Bore for Secure Mounting: The 1:12 tapered bore ensures precise interference fit when mounted with adapter sleeves, eliminating creep and maintaining positional accuracy under heavy loads and vibration conditions.
Optimized Internal Clearance for Thermal Management: The C3 radial clearance accommodates thermal expansion during operation, preventing premature failure due to excessive preload and maintaining optimal performance across the specified temperature range.
High-Speed Capability with Nylon Cage: The glass fiber reinforced nylon cage provides excellent high-speed performance with reduced friction and minimal lubrication requirements, contributing to the bearing's 4,300 rpm limiting speed.
Superior Material Construction: Both rings and balls manufactured from high-carbon chrome steel ensure durability, wear resistance, and long service life in demanding industrial environments.
