—— Product Description ——
Cylindrical roller bearings are precision-engineered rolling-element bearings designed to handle high radial loads and operate efficiently at high speeds. They use cylindrical rollers instead of balls, allowing for greater contact with the raceways, which enhances load capacity and reduces friction.
—— Product Advantages ——
1. High Radial Load Capacity – The large contact area between the rollers and raceways enables these bearings to support heavy radial loads.
2. Low Friction and High Speed – The rolling elements reduce friction, making them suitable for high-speed operations.
3. Axial Load Limitation – Standard cylindrical roller bearings primarily support radial loads, but some designs can accommodate limited axial loads.
4. Various Configurations – They come in different types (NU, NJ, NUP, N, etc.), offering flexibility in handling axial displacement and different load conditions.
5. Detachable Design – Many cylindrical roller bearings have separable inner and outer rings, making installation and maintenance easier.
