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: Why are cylindrical roller bearings suitable for traveling support?: Should be the inner ring and the outer ring without the edge of the can do moving support.

Q: Which column roller bearing brand is good?: you can look at yourself, they recently in the Qingdao market to great influence, you can understand.

Q: What are the differences between cylindrical roller bearings nu208m and nu208em?: E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!

Q: Can cylindrical roller bearings bear high temperature?: Bearing is not high temperature grease is not high temperature, a grease temperature does not exceed 120 degrees, high temperature will lead to bearing lubrication performance, unable to work, in fact, the bearing itself can be high temperature resistant.

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: 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: The Russian bearing suffix No. ZST is a cylindrical roller bearing: 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?: So under normal circumstances, the bearing bore and the shaft is no gap.But do you mean that the inner ring and the shaft of the bearing are fixed,

Q: Cylindrical roller bearingWhat are cylindrical roller bearings, are they available in Kunshan?: This is the simple cylindrical roller bearing rolling body is cylindrical roller, divided into full (no fixed retainer) and belt retainer 2 categories, because the rolling roller, so the axial bearing capacity relative to the ball bearing to be bigger.

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.
