Product Applications:

Cylindrical roller bearings are widely used in machinery and equipment, electric power, steel, metallurgy, petroleum,

chemical engineering, machine tool, spinning, car, electrical machine, precise instrument,

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: 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: Double row cylindrical roller bearings how to disassemble?: If it is replaced, use the flame to heat it quickly under the conditions permitted!

Q: Why cylindrical roller bearings can not bear axial load?.: Bearing bearing axial force or radial force is determined by the structure of the bearing, thrust ball bearings are also called plane bearings, which are mainly used to bear axial force; cylindrical roller bearings can bear radial forces and are not suitable to bear axial force.

Q: Why does cylindrical roller bearings fail abnormally?: 5, improper reinforcement of uranium bearing seat, so that the bearing capacity of the axle is uneven, the bearing seat is provided with holes, or some fasteners, such as a compression screw, etc., are supported, and the supporting parts are provided with grooves or printing places near the roller track of the cylindrical roller bearings.

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: What does "cylindrical roller bearing" ENV mean?: Cylindrical roller bearings, the basic model suffix ENV meaning:E: enhanced design with improved bearing load capacityN: the outer ring of the bearing is provided with a stopping grooveV: full installed roller (no cage)

Q: Rolling bearing face to face or back to back on the use of cylindrical roller bearing pairs, the speed limit will be reduced? Please, thank you!: Cylindrical roller bearings, applicable speed can be very high, check all kinds of high speed motorized spindle bearing configuration will know.

Q: How to calculate the clearance of bearings, such as 23226 double row cylindrical roller bearings: 3, the bearing clearance in different conditions: the bearing clearance can be changed under different conditions, in particular, can be divided into: 1) the original clearance: the original bearing clearance refers to the complete installation in front of the machine after the bearings, the clearance in a free state of the. In fact, the original clearance is not to be measured by measurement, so the original clearance is often replaced by a test clearance. The inspection is in clearance inspection status, applied in measuring load conditions, clearance data instruments detection and, strictly speaking with the original bearing clearance is not the same, but little difference in the readings on the two in general, so it can replace each other without causing much error. 2) effective clearance: effective clearance, or work clearance, refers to the bearing in the installation of the host, in a certain load, to a certain temperature rise in a stable state of operation, bearings exist in the actual clearance. Obviously, the effective clearance is smaller than the original clearance.And 4, bearing clearance: clearance of bearing is to ensure that the bearings are to operate flexibly without blocking, but also requires that can ensure the bearing running smoothly, the bearing axis has no significant settlement, and the number of rolling elements bear the load as much as possible. Therefore, the clearance of the bearing has a great influence on the dynamic performance of the bearing (noise, vibration and friction) and the rotation accuracy, and the carrying capacity (wear and fatigue) of the bearing.

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.
