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: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: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: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: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!: Well, as long as the shaft is well done and the structure is reasonable, what can't be done? I haven't seen the theory of 30%. Cylindrical roller bearings are easy to process, so they have high precision and high limit speed.

Q:For example, NU, NJ, N, RNU, NUP, NF, NO, NN, RN, what do you mean, who can tell me about that hero?: NU outer ring, double retaining ring, inner ring without edgeNJ outer ring, double retaining ring, inner ring, single edge

Q:KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?: Bearing accuracy grade standards for, divided into 0, 6X, 6, 5, 4, 2, six grades.The accuracy of bearings is increased in order of magnitude 0, which is adequate for general 0, but requires 5 or higher accuracy when used in other conditions or situations.In most cases, it is sufficient to apply KOYO bearings (tolerance grade PN) with general dimensional accuracy and rotational accuracy. When higher requirements are required, the bearings require higher levels of accuracy, for example, the spindle axis of the machine toolBearing. In order to achieve higher precision requirements, the standard specifies the tolerance levels of P6, P6X, P5, P4 and P2. KOYO also specified P4S, SP and UP tolerances for some special bearings in accordance with company standards.

Q:What are the components of cylindrical roller bearings?: Compared with the deep groove ball bearings of the same size, this kind of bearing has larger radial load capacity, and is also suitable for high-speed rotation from the structure.

Q:Is the nu240em cylindrical roller bearing split?: No, nu240em cylindrical roller bearings are integral.Bearing type: cylindrical roller bearingNew model: NU240EMOld model: 32240EHInternal diameter (mm):200Outside diameter (mm):360Width (mm):58

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.

Q:Double row cylindrical roller bearings how to disassemble?: The inner ring is heated and expanded and removed rapidly; flame cutting is used directly.
