Cylindrical Roller Bearing
Description
Cylindrical roller bearings have no ribs on either the inner or outer ring, so therings can move axially relative to each other. These can be used as free-end bearings. Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.Cylindrical roller bearings are available in many designs, series and sizes. The majority are single row bearings with a cage. High-capacity bearings, single and double row full complement bearings (without a cage) complete the international standard assortment listed.
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.
Application of cylindrical roller bearings:
Cylindrical roller bearings are used in a variety of applications. Examples include mining, petroleum production, power generation, power transmission, cement processing, aggregate crushing, and metal recycling. Some cylindrical roller bearings are used in briquetting machines, rubber mixing equipment, rolling mills, rotary dryers, or pulp and paper machinery. Others are used in construction equipment, crushers, electric motors, blowers and fans, gears and drives, plastics machinery, machine tools and traction motors and pumps.
F&Q
Q:How long es cycle of bearing life?
A:According to international standards, at least a year and a half , up tu 2 years
Q:How to maintenance bearing
A:Add to lubricantes on time
Q:Have diagram for bearing
- Q: NSK cylindrical roller bearings EW/EM series of differences and characteristics
- E international is called "reinforced type" load, also means to increase rolling bodyW international is called a steel cage
- Q: How much is the axial force of double row cylindrical roller bearings? How is it calculated?
- The cylindrical roller bearings have ribs can withstand certain axial force, the axial force for cylindrical but still belongs to the non normal stress, can cause early failure of the bearing, it is generally not given the axial bearing capacity, no formula
- Q: In the car there is a cylindrical roller, the size of the diameter of 25mm, the outer diameter of 32mm, width of 9.5mm, who knows what the standard size, have direct purchase Mody, thank you!
- This could be a car only bearing! NSK sample short column can not find the corresponding model!
- Q: Can you make it clear? I don't understand. Thank you for being here first.
- A rolling body is a short cylinder.The inner ring (or outer ring) of the bearing can be split.
- Q: What are full cylindrical roller bearings?
- Full cylindrical roller bearingCommon cylindrical roller bearings1, single row full cylindrical roller bearingsNCFNJG2 、 double row full cylindrical roller bearingNNCLNNCFNNCNNFTwo, not common full cylindrical roller bearings1, full spherical cylindrical roller bearings2, CARB ring roller bearings
- 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: How should I find the concentricity of cylindrical roller bearings after installation?
- Any form of assembly, adjustment center is a very troublesome thing, but also in the measuring installation is not very complete, the usual method is to in the base below (or below) thin copper with different thickness, until you feel better, but each installation to re adjust. So, in the machining process, try to use special fixtures and parts drawing in tol and other measures to avoid such a remedy".
- 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? ?
- The higher the speed, the greater the centrifugal force, this point should be mastered. If the grease of good quality, from the bearing chamber to consider the change of the bearing chamber space, the sides of the bearing sealed by using injection nozzle gun grease can improve the lubrication condition.
- Q: The thrust cylindrical roller bearings do not need the bearing seat, and the thrust bearings, shaft rings and seat rings on our unit are all in the bearing seat, often broken. The rotation of the 1. shaft in the bearing seat will not be affected, moreover, the shaft will have radial runout. 2. do not use the bearing seat, usually how to refuel?.Are there any field installation drawings or data on thrust bearings?. Thanks a million!
- In general, this kind of bearing does not use the bearing seat
- Q: Why are there no double row cylindrical roller bearings in the mechanical design manual?
- Normally, the inner diameter of the bearing should be in interference fit with the shaft (for some light loads, too, with a transition fit).
