Cylindrical Roller Bearing Introduction

Rolling body is cylindrical roller bearings - Radial. Cylindrical roller bearings internal structure of the roller was 90 ° perpendicular cross arrangement (which is also cross roller bearings origin of the name), equipped with a gap between the roller cage or spacers can prevent tilting roller or rollers mutual ground between the police, effectively preventing the increase in rotational torque.

Inner or outer wall of the cylindrical roller bearings, the inner and outer ring can be relative to the axial movement, so you can use as a free end bearings. On either side of the inner and outer ring of a double-wall, the other side of the ring has a single wall of the cylindrical roller bearings that can withstand a certain degree of axial load direction. General use of steel stamping cage, or copper alloy solid cage. But there are also some use of polyamide forming cage.

Industrial Application of Cylindrical Roller Bearing

Cylindrical roller bearings apply to electric machine, machine tool, petroleum, rolling mill, loader-unloader, transporter and all kings of machines.

Product features of cylindrical roller bearings. Cylindrical roller bearing belongs to separable bearing. It’s convenient for installation and dismantling. Cylindrical roller bearing concludes single row, double row and four rows cylindrical roller bearing. The single row cylindrical roller bearing is used the most widely

According to its capped edge of collar, cylindrical roller bearing falls into N, NU, NJ, NF and NUP, etc.

Q:For example, NU, NJ, N, RNU, NUP, NF, NO, NN, RN, what do you mean, who can tell me about that hero?: N outer ring without edge, inner ring double edgeRNU no inner ring, NU typeNUP outer ring, double retaining ring, inner ring, single edge, with flat retaining ringNF outer ring, single edge, inner ring, double edgeNO doesn't know

Q:Cylindrical roller bearings NUP2311E mounting dimensions: Da (max): 69Da (min): 64DB (min): 72DC (min): 80Da (max): 111What are the specific meanings of these dimensions? Thank you, master: Da means shoulder diameter, that is to say, the maximum shoulder size is 69mm, and the minimum is 64mm

Q:What is the maximum rotational speed of a single row full cylindrical roller bearing?: FAG single row full cylindrical roller bearingsFAG single row full cylindrical roller bearings can bear large radial loads, and can also bear single direction axial load. Axial positioning can be guaranteed by a symmetrical arrangement of similar bearings. NCF, 29V, NCF, 30V series of bearings have two fixed inner ring, the outer ring has a baffle, they can only bear the direction of the outer edge of the fixed axial load. The NJ23VH series bearings can bear the axial load toward the inside of the inner ring, and their rollers are fixed in the outer ring, even if the inner ring is taken away. The two rings are tight fit, easy installation and disassembly.

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.

Q:Is the roller bearing and the bearing chamber movable in the tapered rotor motor?: E in cylindrical roller bearing is the meaning of improving internal cage design, similar to the SKF cylindrical roller bearing EC form, this type of bearing than without E, is to strengthen the design, the roller is filled more larger to increase the load. From the load point of view, it is better to choose E.

Q:For bearing type, no outer ring single row cylindrical roller bearings, bore 40, thickness 21, roller diameter 8, roller length 12: Specific circumstances need to be further confirmed with your drawings.Reminder: please buy the product specifications and product quality guarantee, so as not to buy fake and inferior bearing products.Handmade, thank you for your adoption, and if you have any questions, please continue to ask.

Q:Cylindrical roller bearings, in the grease after the operation for a short period of time, the grease was thrown out (thrown to the end cap), resulting in roller and raceway between the lack of grease, lubrication poor. Decomposition found that the roller has round circumferential friction marks, but also on the roll, but compared to the roller is very slight. And there are relatively sound bearings, abnormal sound.Is this phenomenon normal? What if it doesn't work? What was the reason? What's the solution? StopThanks for your help!Assuming the grease is no problem, viscosity, consistency, selection is no problem If exclusion is the problem of grease, what other reasons can this be the case? ?: If the grease is dry, adhesion is not good, some of the high temperature grease stored for a long time will be dry, it will apply to the bearing is easy to get rid of, especially now the winter oil solidification, the lubrication effect is less. It is recommended to use low temperature grease in winter or add some oil to dilute it. The best way is to change the grade of grease. If the inner ring of the bearing can be removed, grease can be filled from it.

Q:Why cylindrical roller bearings can not bear axial load?.: The thrust bearing retainer plate and two pieces of circular hole of the ball and the ball hole and shaft wear in the park, circular plate, steel ball track between two plate, shaft and the bearing seat of the top plate in the round two sides, in addition to the track groove, it is not binding the radial direction, so it cannot withstand the radial load.The radial bearing by the size of the two steel ring, steel ball size between steel ring, steel ring diameter fixed by a bearing seat, shaft mounted on a small steel ring, binding only in the radial direction and axial direction of the load is not binding, so it cannot withstand the axial diameter.

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:Why are there no double row cylindrical roller bearings in the mechanical design manual?: but they move axially with the roller and the outer ring?If so, the cylindrical roller bearings without bearings on both sides of the bearing should be normal
