Features
1.) Offers a complete range, both metric and inch sizes available in metric and
imperial bore sizes ranging from 12 to 1320 mm.
2.)High radial load capacity - making cylindrical roller bearings suitable for high
speed applications.
3.)Designs - designated NU, NJ, NUP, N or NF for single row bearings and NNU or
NN for double row types, defines the bearing ring rib configuration.
4.) Cages - Available with pressed steel, machined brass and polyamide cages
throughout the range.
5.) Special designs - manufactures a range of four-row cylindrical roller bearings,
primarily designed for use as steel mill roll-neck bearings.
6.)Bearings are also available with both lubrication holes and a machined
lubrication groove on the outside surface of the outer ring.

Factory
- Q:The Russian bearing suffix No. ZST is a cylindrical roller bearing
- Well, you have to write out the whole model. The suffix code is not used to distinguish the bearings, but it helps to explain the structure of the bearings and the material.
- Q:What kind of material is used for cylindrical roller bearings?
- Ah, you ask what material to do, of course, with the bearing steel do ah. Bearing steel, however, is well distributed. Generally use GL15#
- Q:Attention problems of cylindrical roller bearings
- 4, when the interference is large, the oil bath heating or inductor heating bearings can be used to install the heating temperature range of 80 degrees -100 DEG C, the maximum can not exceed 120 degrees centigrade. At the same time, the nut or other appropriate method is used to fasten the bearing so as to prevent the contraction of the bearing in the direction of width and to create a gap between the collar and the shaft shoulder. 5, single row tapered roller bearings installed, the final adjustment should be clearance. The clearance value shall be determined according to the working conditions and the magnitude of the interference fit. Test shall be carried out when necessary. Double row tapered roller bearings and pump shaft bearings have been adjusted for clearance at the factory, and no adjustment is necessary during installation. 6, the bearing should be installed after the rotation test, the first for the rotary shaft or bearing box, without exception, then the power for no load, low speed operation, and then gradually increase as the functioning of the rotation speed and load, and to detect noise, vibration and temperature, abnormal, should stop running and check. The running test is normal and can be used before delivery.
- Q:Double row full cylindrical roller bearings, NNCF5008 installation, we need to pay attention to the direction of it?
- In theory, cylindrical roller bearings provide radial force, so there should be no direction.
- Q:Why are cylindrical roller bearings suitable for traveling support?
- Cylindrical roller bearings without inner sides of the inner ring or outer ring, whose inner and outer rings can be moved relative to the axial direction, so they can be used as free end bearings.
- Q:How to check the thrust cylindrical roller bearings?
- Bearing dimensions (or bearing samples) have "basic rated load (KN)", this column can be directly detected, in general, according to the use of appropriate multiplied by a (1.2~1.5) safety factor. In accordance with the requirements of the design manual, the equivalent load can be calculated (considering the speed, temperature, load and stability).
- Q:KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?
- The processing of the mating surface, especially the mating surface, is not done in a single clamping. The use of the bearing seat also causes misalignment, such as a flange bearing seat or a vertical KOYO inlet bearing block. As the work load causes the shaft to bend and deform, and also causes the inner and outer ring of the bearing to tilt, it will also appear misalignment.The main products are: KOYO bearing rolling bearing, deep groove ball bearings, high precision bearings, self-aligning bearings, bearings, plane ball bearings, cylindrical roller bearing, linear guide bearing, ball screw bearings, miniature linear guide bearing, cross roller guide bearings, reciprocating rotary bearings, ball bearing slide bushing, group cam follower.
- Q:Can it be used for axial alignment? Forty-fiveWhat is the function of the flat retaining ring of NUP cylindrical roller bearings with flat retaining rings? Can it be used for axial alignment?How much axial force can I bear then?You are the ZWZ? Can you make a friend?!How much axial force can you bear? Do you have a formula or a recommended value?NUP is needle roller bearings, brothers, I dialed the wrong number:What is the function of the flat retaining ring of the needle roller bearing with flat ring NUP? Can it be used for axial alignment?There seems to be no experts here, all mixed up
- Yes, the function of the flat ring is to bear the axial force and be used for axial positioning.
- Q:How much is the shaft shoulder height of the 81105 cylindrical roller bearings with inner diameter 25mm?
- The shoulder height (diameter) shall be smaller than the big diameter of the bearing (less than 42), mainly for easy unloading.
- Q:Why should the main shaft be coupled with double row cylindrical roller bearings?
- Because double row cylindrical roller bearings with high carrying capacity, high precision, separation, easy installation and disassembly, mainly used in lathes, milling machines, machining centers and other high-precision machine tool spindle. Hope to be of help to you.
