Full complement cylindrical roller bearings are capable of carrying higher radial loads than bearings that utilize a cage and roller design

PRODUCT FEATURES:

• Full complement construction, no cage included

• Largest possible amount of rolling elements, so very high radial load carrying capacity, high rigidity and suitable for particularly compact designs

• The design of the outer ring facilitates a great amount

of internal axial float capacity

APPLICATIONS:

• General machine industry

• Gear drives

• Rolling mills

• Crop shears

PRIMARY TYPES:

• Non locating bearings: only radial load carrying capacity

• Semi locating bearings: besides a high radial load carrying capacity, also a small axial load

carryingcapacity in one direction. This enables the bearing to locate a shaft unidirectional.

• Locating bearings: in addition to high radial load capacity also capable of carrying small axial load in both directions.

Full complement cylindrical roller bearings are designed to withstand heavy loads. Under the same width, this kind of bearing has extremely high bearing capacity compared with the traditional bearing with cage, and the radial section is small, which can save space, but the speed is relatively low. In order to make the bearing work normally, in the case of continuous operation, the bearing must bear a certain minimum load, that is, C/P<25. Otherwise, wear will be aggravated due to insufficient lubrication and high-speed operation. All multi-row cylindrical roller bearings have a lubrication groove and lubrication holes in the outer ring.

The full complement cylindrical roller bearing has two inner rings, which are connected together by a clamping ring and cannot be separated. Due to the large distance between the two rows of rollers, it can also withstand overturning moments. There are two retaining grooves on the surface of the outer ring, which can be positioned axially. This type of bearing is equipped with contact sealing rings on both sides and lithium base grease inside, and the operating temperature is limited to -40℃～+80℃. Under certain conditions, this type of bearing does not need maintenance, but when there is water vapor or pollution during operation, and often at medium or high speed, it must be lubricated. In the case of oil lubrication, it is necessary to remove the sealing ring and clean the grease in the bearing. When oil lubrication is used, the running time is increased by 30%.

SINGLE ROW: NCF

• Single inner ring with two fixed flanges

• Single outer ring with one fixed flange

• On the flangeless side of the outer ring is a retaining ring inserted which keeps the bearing

components together

• The retaining ring is for handling purposes only, it cannot be exposed to axial load

• Outer ring is located with a snap ring

SINGLE ROW: NJG

• Inner ring with one flange and one free side

• Single outer ring with two fixed flanges

• Special: Mainly for applications with very high radial load at low rotational speed

• Standard: self-retaining set of rollers so the rollers cannot fall out even if the inner ring is

removed, which simplifies the assembly

DOUBLE ROW: NNC

• Inner ring with 3 fixed flanges

• Two outer rings with internal flange

• Oil groove and holes in outer ring

DOUBLE ROW: NNF

• 2 identical inner rings held together with metallic spring

• Single outer ring with a fixed central flange

• Oil groove and holes in both rings

• PP: sealed on both sides and lubricated

• 2NR: 2 snap rings

DOUBLE ROW: NNCF

• Inner ring with 3 fixed flanges

• Single outer ring with one fixed flange

• Outer ring located with one snap ring which keeps all bearing components together

• Oil groove and holes in outer ring

DOUBLE ROW: NNCL

• Inner ring with 3 fixed flanges

• Single outer ring with one fixed flange

• Outer ring located with a central snap ring to keep all bearing components together

• Oil groove and holes in outer ring
