High Speed NTN brand 32217 Tapered Roller Bearings made in Japan
Tapered roller bearings are generally of separable design and have tapered cone and cup raceways between which tapered rollers are arranged. Their design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) loads.
According to dimensional standard difference, tapered roller bearings can be grouped into metric and inch size series.

FAQ1: Is the NTN 32217 bearing suitable for truck axles or gearboxes?
Yes, the NTN 32217 bearing is highly suitable for truck axles and gearboxes, as well as other heavy-duty applications. Its ability to handle large radial and axial loads makes it ideal for these demanding environments.
Truck Axles: Tapered roller bearings are a standard choice for the wheel hubs of heavy commercial vehicles. They can support the heavy radial loads from the vehicle’s weight and the significant axial loads generated when the vehicle turns.
Gearboxes and Industrial Machinery: In industrial applications, the 32217 is commonly used in gearboxes and other heavy-load machinery, such as construction equipment, mining machinery, and rolling mills. Its robust design ensures durability and reliable performance in these harsh working conditions.
FAQ2: How does the 32217 bearing perform under high-speed applications?
The NTN 32217 bearing is designed for demanding, high-load applications, but its speed capabilities are more moderate compared to other bearing types.
Limiting Speeds: According to NTN’s specifications, the limiting speed for this bearing is typically around 2400 RPM for grease lubrication and 3200 RPM for oil lubrication.
Comparison: While this is a high speed for a heavy-duty tapered roller bearing, it is not as fast as an angular contact ball bearing, for example. Tapered roller bearings prioritize high load capacity and rigidity over extreme high-speed performance.
Performance: Within its specified speed limits, the 32217 performs reliably, providing a stable and durable solution for applications like truck transmissions and industrial gear drives.
