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 should the main shaft be coupled with double row cylindrical roller bearings?: Separable, easy to install and disassemble, mainly used in lathe, milling machine, machining center and other high-precision machine tool spindle. Hope to be of help to you.

Q:How to check the thrust cylindrical roller bearings?: Bearing dimensions (or bearing samples) have "basic rated load (KN)", this column can be directly detected, in general, according to the use of appropriate multiplied by a (1.2~1.5) safety factor. In accordance with the requirements of the design manual, the equivalent load can be calculated (considering the speed, temperature, load and stability).

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:Full use roller bearings: The service is applied to all axle box bearings, including FAG cylindrical roller bearings, spherical bearings and tapered roller NSK bearings. In addition, FAG industry services also provide support to customers in the rail industry who introduce maintenance management systems. INA bearing agent Chinese by helping clients improve internal maintenance procedures, F IS can enhance the data exchange between various departments, and clearly useless procedures, such as entry in IT system and database in different kinds of data. This reduces the cost of raw material management and speeds up maintenance activities. NSK it is very important for the effective maintenance management to install the bearing units rapidly and effectively in china. At the same time, the F IS offers a range of energy saving bearing heaters. Including the FAG Powertimken series induction heater, to enable customers to reduce the installation time of bearing, NSK bearings so as to shorten the downtime, instead of using the traditional heating method (oil bath heating stove, or board). FAG is a research and development partner and supplier of the world's leading Boeing 787 manufacturer. The quality, reliability and efficiency of Schaeffler's aviation bearings, INA bearings, price fits, and performance in extreme conditions, the INA bearing agent provides support for the international space navigation corporation. FAG's bearing technology is used on almost all modern aircraft.

Q:Cylindrical roller bearings NUP2311E mounting dimensions: Da (max): 69Da (min): 64DB (min): 72DC (min): 80Da (max): 111What are the specific meanings of these dimensions? Thank you, master: Da means shoulder diameter, that is to say, the maximum shoulder size is 69mm, and the minimum is 64mm

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: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).

Q:My notes is the former has a taper hole on the cone position preload, the latter is a nut. But the online information seems a little different. Are the preload methods for two direction thrust angular contact bearings and angular contact ball bearings the same?: Dissimilarity！ The former is mainly used as the support of the shaft with larger load. The main prevention is the radial runout, which is usually used individually, so there is not much demand for the preload.

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:Why cylindrical roller bearings can not bear axial load?.: The thrust bearing retainer plate and two pieces of circular hole of the ball and the ball hole and shaft wear in the park, circular plate, steel ball track between two plate, shaft and the bearing seat of the top plate in the round two sides, in addition to the track groove, it is not binding the radial direction, so it cannot withstand the radial load.The radial bearing by the size of the two steel ring, steel ball size between steel ring, steel ring diameter fixed by a bearing seat, shaft mounted on a small steel ring, binding only in the radial direction and axial direction of the load is not binding, so it cannot withstand the axial diameter.
