Nji Series Full Complement Cylindrical Roller Bearings - China

SBI Full Complement Cylindrical Roller Bearings (Full Complement

Bearings) are designed to carry heavy load.

Comparing with traditional

bearings with cage, full complement cylindrical bearings have much

higher loading capacity.

The radial cross section of the type of

bearings is very small.

So it can be very space – saving.

However the

limiting speed of the bearings is relatively lower.

All the multi – row

cylindrical roller bearings are with a lubrication groove and one nipple

on the outer ring.

A minimal load is required (C/P <25) for the bearings

to run well in succession.

Otherwise wear may happen when lubrication is

running out or rotating speed is high.

NCF•••V type Full Complement

Cylindrical Roller Bearings are with a single rib on one side of the

outer ring.

A snap ring is on the other side which makes the shaft be

stationary in single direction.

The axial gap “s” inside the bearings

ensures the axial displacement of shaft to the bearing housing case.

For

this “s” value, please consult SBI technical service.

NJ•••V type Full

Complement Cylindrical Roller Bearings is applied under very high loads

and slow rotating speed conditions.

The rollers are self – locked and

will not fall apart even if the inner ring is removed.

Therefore, the

mounting and dismantling of the type of bearings are convenient.

The

bearings can carry axial load in one direction.

NNF•••2LSNVY type double

– row Full Complement Cylindrical Roller Bearings are with two

inseparable inner rings joined by a holding ring.

There is a rib in

middle of the outer ring.

The bearings can carry axial load in both

directions and be used ad stationary bearings.

As the distance between

the two rows of rollers is big, the bearings can also take some

overturning moment.

On the outer ring there are two snap grooves for

axial orientation.

This type of bearings is with contact seals on both

sides and with lithium based grease.

The operation temperature limit for

the bearings is from -40 to 80℃.

The kind of bearing is generally

free of maintenance under some certain conditions.

But in case that

there is vapor or dust, and the bearings are running in medium or high

speed, supplement lubricant is absolutely necessary.

If using rare oil

as lubricant, the seals should be removed and all the grease with the

bearings be washed out.

In that case, the limit rotating speed can be

increased 30%.

The dimension tolerance and geometry deviation of the

type of bearings are in accordance with Grade P0 of GB 307.1-1994(ISO492-

1994).

And the normal radial clearance is with group C0 - Bearings with

normal radial clearance of Group C2 or C4 are also available.

In that

case some suffix should be added to the bearing code.

For example,

bearing with group C3 are generally selected for the plastic extruders.

If you have requirement for higher grade bearings, please contact SBI

service.

For mounting tolerance, you can refer to the selection

principle of housing tolerance and shaft tolerance limits.

Some certain

axial loads are allowed for the type of bearings.

In that case,

sufficient lubrication is a premise.

In the single direction stationary

bearings and stationary bearings, the rib that carrying axial load must

be fully supported.
