Cylindrical roller bearings are designed with a straightforward structure consisting of cylindrical rollers in linear contact with the raceways. These bearings are known for offering high load capacity primarily under radial loads, and their suitability for high speed rotation thanks to the low friction between rollers and ring ribs.
The single-row bearings are identified by designations such as NU, NJ, NUP, N, or NF, while double-row bearings bear designations such as NNU or NN, depending on whether side ribs are used. The inner and outer rings can be separated for all types of bearings.
Specialized bearings feature lubrication holes that are supplied in the inner ring. This makes it easy to refill and replace grease in sealed types, helping to maintain optimal lubrication and extend the lifespan of the bearings.
By using specialized bearings equipped with a locating snap ring, it is possible to reduce the number of components required for the sheave. This can help to reduce costs and simplify maintenance, making it an economical choice for crane operators.
Overall, specialized bearings for crane sheaves offer a range of benefits that make them a worthwhile investment. Consider them for your next crane project.
