Pair list cylinder roll sub bearing have cylindrical inner hole and inner hole of taper shape ‘ The rearmounted code of the bearing adds K) Two kinds of structure. The bearing have compact, the intersection of rigidity and old, large receiving advantaging such as being out of shape and little behind the load bearing capacity, especially suitable for the main shaft of the lathe to support. The inner hole of taper shape can also play a role in adjusting the backlash in trace, and can simplify the device structure of the localization, install and dismantle conveniently. Commonly used pair lists the cylinder and rolls there are the sub bearings in the form of making and making several kinds:

NN, NNU type
It, inner circle be blocked both sides block the middle in not having after if you can’t have outer lane of NN3017 bearing, blocking. Displacement that can be allowing to produce two directions axially between the axle relative bearing seats.
Block and block, inner circle be blocked to be had outer lane of Model NNU bearing both sides in not having at the middle. Displacement that can be allowing to produce two directions axially between the axle relative bearing seats. So, this kind of structure is suitable for moving about the end bearing. Maintenance shelves of this type bearing adopt the car to make the entity and keep the shelf more.
NNF type
Model NNF bearing whether pair list, load cylinder with, get away sub bearing while being full, the bearing blocks the outer lane from a strip, the structure pattern of the inner circle that two have pair to block. The son is guided by the blocking of inner circle to roll, two inner circles are by fastening and enclosing fixing together. Except this structure can bear very large radial load and axial load, can also bear and topple the moment, so, use dailily as fixed end bearing.
Both sides of Model NNF bearing are adopted contact-typely and sealed. Fill out lubricating grease in the bearing, the working temperature of lubricating grease is – 50 ¡æ to 110 ¡æ, but is limited by sealant, the working temperature of the bearing is only limited to – between 40 ¡æ to 80 ¡æ. Under using the situation with better operating mode, there are sealed NNF bearings that do not need to maintain, it last steam if bearing or pollute the environment,and for in, when not operating at a high speed, can supplement and lubricate the bearing through lubricated oil groove and lubricating oil hole on the outer lane.

Bearing use
Large and medium sized motor, rolling stock, main shaft of the lathe, internal-combustion engine, generator, gas turbine, gearbox, rolling mill, shaking sifting and handling machinery,etc.. Precision grade
The cylinder rolls the sub bearing can divide PO, P6, P5, P4, P2 according to the precision grade. The precision grade is from low sequentially to high sequencing.
Warm suggestion: Because marque kind numerous, picture can’t one first uploading, some products can’t be put on the shelf one by one either, hope to understand, the product of this shop is complete, the whole kind, such as finding the type needed in this shop, please contact shopkeeper!
