The specifications and models of cylindrical roller bearings mainly include the following:

Single row cylindrical roller bearing: This type of bearing has a simple structure, is easy to install and maintain, and is suitable for bearing radial loads in a single direction. Common models include NU, NJ, NUP, N, NF, etc.

Double row cylindrical roller bearings: Compared to single row bearings, double row cylindrical roller bearings can withstand larger radial loads and have a more compact structure, making them suitable for space limited applications. Common models include NNU and NN type 2.

Four column cylindrical roller bearing: This type of bearing is suitable for situations where it needs to withstand extremely large radial loads, usually using a pin cage .

Specification parameters of cylindrical roller bearings:

Thickness: For example, the thickness of model 42505EH is 18mm.

Accuracy level: For example, P0 level accuracy .

Usage: For example, used in construction machinery .

Rolling element type: For example, cylindrical roller .

Retainer material: For example, brass solid .

Application scenarios of cylindrical roller bearings:

Reducer: In the reducer, cylindrical roller bearings can withstand heavy loads and impact loads, suitable for high-speed rotating occasions.

Pulley block: In the pulley block, cylindrical roller bearings can provide stable support and rotational performance.

Printing machinery: In printing machinery, cylindrical roller bearings can ensure stable operation and precise control of the equipment
