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.
Cylindrical roller and raceway for the line contact bearings. Load capacity, the main radial load. Rolling ring wall friction is small, suitable for high-speed rotation. According to ring without ribs, can be divided NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. The bearing is the inner, outer separable structure.
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.

- Q: Why are cylindrical roller bearings suitable for traveling support?
- Cylindrical roller bearings without inner sides of the inner ring or outer ring, whose inner and outer rings can be moved relative to the axial direction, so they can be used as free end bearings.
- 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: KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?
- The allowable deviation of 1, the inner and outer diameter, width and the width of the assembly allowable deviation 2, roller diameter and the outer round round in group 3, the diameter of the chamfer size bounds value 4, the width of the allowable rotation accuracy (momentum and rotating body beating related projects) 1, inner ring and the outer ring allows for radial and axial beating 2, inner ring 3, allowing the lateral runout of outer surface inclination to allow changes in volume 4, the thickness of the thrust bearing raceway permissible variation
- Q: What are the differences between cylindrical roller bearings nu208m and nu208em?
- E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!
- Q: Attention problems of cylindrical roller bearings
- High temperatures often indicate that cylindrical roller bearings are in exceptional condition. High temperature is also harmful to bearing lubricants. Sometimes the bearing is overheated and can be attributed to the lubricant in the bearing. If the bearings are longer than the temperature of 125 degrees, even the transfer will reduce the bearing life. The causes of high temperature bearings include: insufficient lubrication or excessive lubrication, impurities in the bearing raceway, extreme high speed, long term overload operation of bearings, etc..
- 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 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: What are full cylindrical roller bearings?
- Full capacity roller bearings are divided into double row full load roller, single row full roller, outer spherical roller, CARB bearingsI am a bearing manufacturer, factory direct marketing, welcome inquiry cooperation. Contact information on personal data
- 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: What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?
- What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?Semi convex, convex roller is in plane roller axis, the outer surface of a continuous or discontinuous convex curved basic cylindrical or conical roller, to prevent the end of the roller and raceway contact stress concentration. The roller is generally defined as a convex roller and a modified roller.
