1218-K-TVH-C4 Bearing Product Overview & Core Advantages
The 1218-K-TVH-C4 is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. This metric bearing features a 1:12 tapered bore for secure shaft mounting and is optimized to handle significant radial loads. Its double row construction provides enhanced stability and load-carrying capacity in a compact bearing size of 30mm width. Pre-lubricated and built with a nylon cage, it offers reliable performance, making it suitable for demanding industrial environments where precision and durability are critical.
1218-K-TVH-C4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| K | Indicates a 1:12 tapered bore for precise interference fit on tapered shafts |
| TVH | Designates the nylon cage material (polyamide) offering reduced weight and smooth operation |
| C4 | Specifies greater radial internal clearance than normal, suitable for applications with thermal expansion or where lower operating temperatures are required |
1218-K-TVH-C4 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing construction provides superior stiffness and can accommodate substantial radial loads (dynamic: 12,870 lbf, static: 5,310 lbf), ensuring stable operation under demanding conditions.
Optimized Cage Design: The nylon cage (TVH) reduces friction, allows smoother operation at moderate speeds, and is corrosion-resistant, contributing to the bearing's longevity.
Tapered Bore Mounting: The 1:12 tapered bore (K) enables precise axial positioning and secure fixation on matching tapered shafts, preventing creep and maintaining alignment.
Enhanced Internal Clearance: The C4 clearance provides additional space between rolling elements and raceways, making it suitable for applications where thermal expansion occurs or where a cooler running bearing is preferred.
Ready-to-Use Lubrication: Factory-lubricated for immediate installation and initial operation, reducing maintenance requirements.
