Product Specifications:
Cylindrical roller and race for line contact bearing. Load capacity is big, mainly bear radial load .
1. Friction coefficient is small, suitable for high speed limit speed close to deep groove ball bearings
2.N and NU type axial movement, can adapt to shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing
3. On the shaft or hole of the processing and the demand is higher, bearing outer axis relative deflection after installation to be kept under strict control, so as not to cause contactstress concentration
4. Inner ring or outer ring separable, easy to install and remove

- Q: Gb/t283 cylindrical roller bearing age number?
- Hello, it's 2007.GB/T 283-2007 roller bearings cylindrical roller bearings overall dimensionsStandard number: GB/T 283-2007Rolling bearings - cylindrical roller bearings - DimensionsRolling bearings - cylindrical roller bearings - DimensionsEnglish, Name:Rolling, bearings - Cylindrical, rolling, bearings - Boundary - Dimensions
- 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: Which column roller bearing brand is good?
- Foreign SKF is better, the domestic is Kazakhstan axis, and then is Taiwan's Rui Rui, you can look at yourself, they recently in the Qingdao market to great influence, you can understand.
- 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: What are the differences between cylindrical roller bearings nu208m and nu208em?
- E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!
- Q: what does that mean? Please enlighten master, thank you.
- Cylindrical roller bearingN216E stands for the bearing retainer as a steel cageN216EM stands for the bearing holder as brass holderThe material of the cage is different (the structure that holds the roller in it for a long time)
- Q: Double row cylindrical roller bearings how to disassemble?
- If it is replaced, use the flame to heat it quickly under the conditions permitted! The inner ring is heated and expanded and removed rapidly; flame cutting is used directly.
- Q: cylindrical roller bearings N210 20Deep groove ball bearings 6120, self-aligning ball bearings 1210, cylindrical roller bearings N210 in the same radial force conditions, the life expectancy of the three levels and how to compare? What is the cause of the high and low?
- In these three bearings, the deep groove ball bearings roll with the bearing outer ring point contact, and the bearing outer ring contact surface is smallest. The self-aligning ball bearing and the outer ring of the bearing are double point contact, and the contact surface is slightly larger than the outer ring of the bearing.
- Q: Why does cylindrical roller bearings fail abnormally?
- Generally, the causes of abnormal failure of cylindrical roller bearings are as follows:1, cylindrical roller bearing manufacturing accuracy is poor, one end of the bearings with loose, and travel source is larger, bearing frame rigidity is poor. Or the bottom of the bearing seat is uneven.2, cylindrical roller bearings axis misalignment (misalignment) axis and the housing of the shoulder to the surface is not vertical, shell installation, bearing two or more holes, different axis.
- 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? ?
- Grease over dry, thin will affect the effect, but also with the brand of grease is also related, you can try several kinds of grease, to see what kind of effect is bestChangshou City Kazakhstan axis electrical and mechanical materials trade, we are agents of a variety of well-known bearings
