BEARING DETAILS

Bearing distributor required NU222 cylindrical roller bearing stock introduction :

Cylindrical roller bearing has different types of designated NU, NJ, NUP, N, NF for single-row bearings, and NNU, NN for double-row bearings depending on the design or absence of side ribs. AST’s cylindrical roller bearings come in the following series with various cage designs and Metric dimensions:

Cylindrical roller bearings introduction :

Single row cylindrical roller bearings with cage are units comprising solid inner and outer rings together with cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling.

N Series - Bearings of N design are single row cylindrical roller bearing and have two fixed ribs on the inner ring that retain the rollers and cage and one smooth outer ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, N Series rolling bearings are used in non-locating bearing units. Also, the N Series bearings have virtually no thrust capacity.
NU Series - Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and one smooth inner ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, NU Series rolling bearings are used in non-locating bearing units. Also, the NU Series bearings have no virtually thrust capacity.

External design (seals, snap ring groove etc.)
ADA Modified snap ring grooves in the outer ring; two-piece inner ring held together by a retaining ring
(for bearings in the NNF 50 series)
ADB ADA + modified internal design
DA Modified snap ring grooves in the outer ring; two-piece inner ring held together by a retaining ring
(for bearings in the 3194 . . series)
K Tapered bore, taper 1:12
N Snap ring groove in the outer ring
NR Snap ring groove in the outer ring, with appropriate snap ring
N1 One locating slot (notch) in one outer ring side face
N2 Two locating slots (notches) in one outer ring side face, 180° apart
-2LS Contact seal, PUR, on both sides

Axial internal clearance :

Guideline values NUP design , NJ design with an HJ angle ring

When measuring the axial internal clearance the rollers may tilt,

causing an enlargement of the measured axial clearance:

2, 3 and 4 series: ≈ the radial internal clearance •

22 and 23 series: ≈ 2/3 the radial internal clearance

Requirements/ Benefits :

• Most modern design

• High speed capability

• High operational reliability

• High running accuracy

• Quiet operation, low vibration

• Low operating temperatures

• Easy mounting

• Little maintenance

• Extremely long service life

BEARING KNOWLEDGE

Bearing damage analyse :

Inspection of bearing and judgment :

In order to determine whether removing bearings can be used to check after the bearings clean, carefully check the roller surface, scroll, status of the mating surfaces, wear of the cage, the increase in bearing clearance and there's no falling damage, abnormal size precision. Non-separation of small ball bearings, supporting inner rings with one hand horizontally, rotate the outer ring to confirm in a smooth rotation State. Tapered roller bearings are separable bearings, rolling element and the Raceway in the outer ring can be respectively checked. Larger bearings cannot rotate, check rolling element and the Raceway, cage, sidewall surface appearance. the importance of as high as possible shall be carefully inspected.
