Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.
Needle Roller Bearings have a high load carrying capacity and can operate at high speeds. They have slim design and are suited where radial space is limited. They are available with or without an inner ring.
Needle roller bearings are a bearing that is classified as either radial or thrust depending on the direction of the load being supported. Needle roller bearings include bearings whose rollers slightly exceed the size range of needle rollers as stipulated by ISO. Needle roller bearings include drawn cup and solid radial bearings, as well as application-specific cam followers, and roller followers. Thrust bearings include thrust needle bearings.
Needle bearings feature a smaller cross-section, higher load-carrying capacity, greater rigidity, and lower inertia forces that facilitate size and weight reductions in machinery. They're designed to withstand oscillation, perform under severe conditions, and interchange with sliding bearings.
Structure of Rolling pin bearing NKI 28/30
This kind of bearings has multiple structures, such as narrow & wide type, with or without inner races, cages, ribs or seals.

Special Directions of Rolling pin bearing NKI 28/30
Bearing running clearance and inner-cutting roundness should be regulated according to different conditions.
Machine tools should be used for press-in fitting or thermal fitting of the bearing
Limited by plastic cages (suffixed with TN) and sealing-element material, operating temperature is -300C---+1000C.
For general-disposition design of bearings, refer to the relevant recommendation in the applied technology of
rolling bearings.
