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.

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.

Industrial Application of Cylindrical Roller Bearing

Cylindrical roller bearings apply to electric machine, machine tool, petroleum, rolling mill, loader-unloader, transporter and all kings of machines.

Product features of cylindrical roller bearings. Cylindrical roller bearing belongs to separable bearing. It’s convenient for installation and dismantling. Cylindrical roller bearing concludes single row, double row and four rows cylindrical roller bearing. The single row cylindrical roller bearing is used the most widely

According to its capped edge of collar, cylindrical roller bearing falls into N, NU, NJ, NF and NUP, etc.

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.

Q:What are full cylindrical roller bearings?: Full cylindrical roller bearingCommon cylindrical roller bearings1, single row full cylindrical roller bearingsNCFNJG2 、 double row full cylindrical roller bearingNNCLNNCFNNCNNFTwo, not common full cylindrical roller bearings1, full spherical cylindrical roller bearings2, CARB ring roller bearings

Q:Cylindrical roller bearingWhat are cylindrical roller bearings, are they available in Kunshan?: The utility model is suitable for occasions where the bearing requirement is higher.

Q:The Russian bearing suffix No. ZST is a cylindrical roller bearing: Well, you have to write out the whole model. The suffix code is not used to distinguish the bearings, but it helps to explain the structure of the bearings and the material.

Q:What's the difference between imported bearings and imported bearings?: The 2 kind of bearing retainer material is mostly copper, and the retainer pin is also copperThere is also a steel retainerImported bearings also have copper and steel

Q:Is the nu240em cylindrical roller bearing split?: Therefore, such bearings need to be installed in the axial load bearing the main components, only at the same time using other types of bearings to withstand axial load on the premise that can be used.

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

Q:How to calculate the clearance of bearings, such as 23226 double row cylindrical roller bearings: First of all for the bearing clearance calculation is a very complicated problem, because the bearing structure of different types, and the usage of different materials, the temperature of different factors such as the clearance is different, and because of the different structure types and some bearing bearing clearance is divided into radial clearance and axial clearance; also need to pay attention to the bearing clearance is usually divided into the following 1. conditions, clearance before installation, usually refers to the bearing manufacturers factory according to the standard to determine the clearance of bearing clearance. 2., after the installation clearance, because the bearing inner ring and the shaft is interference fit, when the bearings installed on the shaft, its inner ring will be as the amount of interference and expansion, resulting in smaller clearance of bearings. 3. clearance work, because the bearing is affected by load and rotating friction in the work, the temperature will gradually increase, will cause the bearing inner ring further expansion, which will make further changes in bearing clearance. However, the main clearance of the bearing is the largest (minimum) diameter of the raceway of the outer race of the bearing, the largest (minimum) diameter of the rolling body and the largest (smallest) diameter of the raceway of the inner race. For example, cylindrical roller bearings, its largest clearance = outer raceway raceway, maximum diameter of -2* roller minimum diameter - inner raceway minimum diameter derived, and conversely, for the smallest clearance. The average user of bearings actually doesn't need to know that.The other 23226 models should be the spherical roller bearing, not double row cylindrical roller bearing.I hope my answer will be of some help to you!

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: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.
