Do you want to know cylindrical roller bearing id od chart?

24 Published by admin Jul 05,2019

Double row cylindrical roller bearings have a cylindrical inner bore and a conical inner bore (bearing rear code plus K). This kind of bearing has the advantages of compact structure, large rigidity, large bearing capacity, small deformation after load, etc., and is especially suitable for machine tool spindle support. The conical inner hole can also play a role of slightly adjusting the play, and can simplify the structure of the positioning device, and is convenient for installation and disassembly. The commonly used double row cylindrical roller bearing id od chart has the following forms:

Bearing id od chart of NN type bearing has no rib on the outer ring, and there are middle ribs on the sides of the inner ring. It is possible to allow displacement of the shaft in the axial direction relative to the bearing housing in both directions.

Bearing id od chart of NNU-type bearings on both sides of the outer ring with a middle rib in the middle of the rib, the inner ring has no ribs. It is possible to allow displacement of the shaft in the axial direction relative to the bearing housing in both directions. Therefore, such a structure is suitable as a swim end bearing. Most of the cages of this type of bearing use a vehicle-made solid cage.bearing id od chart

Bearing id od chart of NNF type bearing is a double row full complement cylindrical roller bearing. The bearing consists of a structure with a middle rib outer ring and two double rib inner rings. The rollers are guided by the ribs of the inner ring and the two inner rings are fastened together by fastening rings. In addition to being able to withstand large radial and axial loads, the structure can withstand overturning moments and is therefore often used as a fixed end bearing--Bearing id od chart

Bearing id od chart of NNF type bearing with contact seal on both sides. The bearings are filled with grease. The operating temperature of the grease is -50 ° C to +110 ° C, but due to the limitations of the sealing material, the operating temperature of the bearing is limited to -40 ° C to +80 ° C. In the case of better working conditions, the sealed NNF bearing does not need maintenance. If the bearing is in water vapor or polluted environment for a long time, and it is running at medium and high speed, it can pass through the lubricating oil groove and the lubricating oil hole on the outer ring. The Bearing id od chart are relubricated.four row cylindrical roller bearing

Four-row cylindrical roller bearings are mainly used in rolling mill machinery such as cold and hot rolling mills and blanking machines. The commonly used four row cylindrical roller bearing id od chart has the following forms:

Bearing id od chart of FC type: consists of two outer rings and one inner ring. Each outer ring has a middle rib on the two sides of the rib and the inner ring has no rib.

Bearing id od chart of FCD type: It is actually a combination of two bearing id od chart for NN type bearings.

Bearing id od chart of FC and FCD bearings allows for axial displacement in the axial direction relative to the housing. Therefore, such a structure is suitable as a swim end bearing. The cage of this type of bearing id od chartmostly uses the car body 13:58.
