NJ,NU series roller bearing

cylindical roller bearing size:N,NJ,NU,NUP series cage:cooper and iron cages material:bearing steel,GCR15 precision:ABEC-1

product  detail description:

Cylindrical roller bearings have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring. This is especially important when accommodating thermal expansion, where both rings must be press-fitted.

It can be grouped into NU,NJ, NUP,N, NF etc. one-row bearing, and NNU, NN,etc. double row bearings.

features:

1 heavy radial and impact loading 2 less coefficient of friction 3 variations of structure

4row cylindrical roller bearing feature high radial load because the rollers and raceway are in linear contact

5 The NU and N types exhibit their best performance when used as free side bearings since they adjust to the shaft axial movement,to a certain extent, relative to the housing position

6 The NJ and NF types carry a certain degree of axial displacement in both directions so they are also used as free side bearings

7. Our company mainly produce both single-row and double-row cylindrical roller bearings: Single-row cylindrical roller bearings (ID.20--1900) Double-row cylindrical roller bearings(ID.20--1500)

8 Moreover, we can manufacture these bearings according to customer's drawings and samples
