description
- Spherical Roller Bearings are particularly suitable for applications where misalignment can arise from error in mounting or from shaft deflection. NACHI Spherical Roller Bearings are manufactured in a number of design and material configurations depending on the type of application and size of the bearing. See Table 1 for the roller, the guide ring and cage design for NACHI Spherical Roller Bearings. They can sustain radial and axial loads.
features
- NACHI's EXQ Series' Internal specifications have been optimized to greatly improve axial resistance load performance - Heat generation of the bearing has been reduced by stabilizing the roller movement during rotation, realizing the world'shighest permissible rotation - Long life has been realized by optimized internal specifications and using high cleanliness steel - Standardized heat stabilization treatment and service temperature up to 200°C - (W33) = Lubricant groove and holes on outer ring - (K) = Tapered bore 1:12
