Single-row Cylindrical Roller Bearings NU 311
Cylindrical roller bearings
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.
1. SPECS: 25*47*12mm
2. Net weight: 0.105kgs
3. retainer material: brass
4. Price:4-5USD/unit
Cylindrical roller bearings features:
1 heavy radial and impact loading2 less coefficient of friction3 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
