NJ306EM NF306 original radial short pulleys bearing cylindrical roller bearing
Cylindrical roller bearings are separable, easy to install and remove, and the most prominent feature is especially for bearings that require an interference fit between the inner and outer rings and the shaft and housing.
If you want to know more details, please feel free to contact us.
Cylindrical roller bearings contact the inspection line between the rollers and raceways, eliminating edge stress. Compared with ball bearings of the same limit size, cylindrical roller bearings have a higher radial load capacity. Structurally, this kind of bearing is more suitable for high-speed rotation
