NJ Series All level quality Single row cylindrical roller bearing
NJ204 205
Something about Cylindrical roller bearings:
1. heavy radial and impact loading
2. less coefficient of friction
3. variations of structure
4. row 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
