Product Description

Type cylindrical roller bearings
Cylindrical roller bearings types include: N, NU, NJ, NF, NUP, NFP, NH (NJ + HJ), NN, NNU, NNF, FC, FCD type
1. N bearing
No outer wall, the inner ring ribs on both sides. Allows the bearing axis relative to the axial direction between the two displacement directions. NU type ribs on both sides of the bearing outer ring, inner ring without ribs. Can allow the shaft between the bearing seat in the axial displacement in both directions. Therefore, such a structure is suitable for use as a mobile end bearings.
2. NU type bearings
Ribs on both sides of the bearing outer ring, inner ring without ribs. Can allow the shaft between the bearing seat in the axial displacement in both directions. Therefore, such a structure is suitable for use as a mobile end bearings.
3. NJ type bearings
Outer sides of wall, inner side with ribs. Can withstand a certain amount of axial load. NF type outer side has wall, inner sides of ribs. Also can withstand a certain amount of axial load. Therefore, such a structure is suitable for positioning the axial direction as a single bearing.
4. NUP bearings
Outer sides of ribs, the inner side of the band (fixed) single-wall, while the other side is detachable flat ring. Can withstand a certain amount of axial load.
5. NN bearings
The outer wall, the inner wall on both sides of the middle of the wall. Allows the relative bearing between the shaft in the axial direction of the displacement produced two, NNU type bearing outer ring ribs on both sides of the middle of the wall, inner wall. Allows the bearing axis relative to the axial direction between the two directions of displacement generated. Therefore, such structure is suitable for swimming-end bearings. The type of bearing retainer multi-use vehicles solid cage.
Double row cylindrical roller bearings

Double row cylindrical roller bearings simplest definition is rolling element is a cylindrical roller and is the two side by side bearing to the heart. Double row cylindrical roller bearings rolling element and the raceway is in line contact, so it is relative to the point contact bearings can withstand a greater load, and the rolling element and ring friction, for high-speed rotating machinery.
Due to large load capacity, high-speed two features, double row cylindrical roller bearings use a wide area, the main purposes are: cranes, large motors, vehicle bearings, generators, machine tool spindles.
Four cylindrical roller bearings Front codenamed FC, FCD, RY, RX, RXK type, they are for high-speed, high-temperature, high radial loads and design.
FC-type
FC-type four cylindrical roller bearing is composed of two outer and an inner ring composed of two outer sides and the middle has a wall, inner wall no.
FCD model
FCD-type four-row cylindrical roller bearings are composed of two cylindrical roller bearings NN combination.

Bearing purposes

Medium-sized motors, locomotives, machine tool spindle, internal combustion engines, generators, gas turbines, gear boxes, rolling mill, vibrating screen and lifting and transport machinery.

 

NNCF 5004 CV full complement cylindrical Roller Bearings are meant for large dimensional applications like mining equipment, over-size industrial gearboxes, wind turbines, etc. These types of bearings come in 22 and 23 dimension series. In the sudden start and stop processes, the conventional bearings don’t work properly as it takes time to form a lubrication film but this type of bearing has a surface which helps in the easy formation of lubrication film.

 

Features:

Deliver high performance in large industrial application
Load carrying capacity is almost 15% higher than normal bearing
It reduces friction and thus reduces heat generation
It operates at higher speeds and has a longer life.
