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: 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: Which column roller bearing brand is good?: you can look at yourself, they recently in the Qingdao market to great influence, you can understand.

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: What's the difference between imported bearings and imported bearings?: Domestic bearings used in the cage and rivet and washer, spacer ring, sealing ring, pillar, pin etc. the material is divided into black metal materials (such as low carbon steel, stainless steel etc.), non-ferrous metal materials (such as brass, bronze and Aluminum Alloy etc.) and non metal materials (such as plastics, phenolic textolite three) etc..

Q: How should I find the concentricity of cylindrical roller bearings after installation?: 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.

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!: Rolling bearing face to face or back to back, the speed limit will be reduced? Yes, especially in order to obtain a large preload or a large gap of the matching. Cylindrical roller bearings in pairs, the limit speed will be reduced? Cylindrical roller bearings do not exist in pairs, one said that you can use the same internal and external diameter of double row, four column cylindrical bearings, the same internal and external diameter of double row, four column bearings, compared to single row cylindrical bearings limit speed will be reduced

Q: The thrust cylindrical roller bearings do not need the bearing seat, and the thrust bearings, shaft rings and seat rings on our unit are all in the bearing seat, often broken. The rotation of the 1. shaft in the bearing seat will not be affected, moreover, the shaft will have radial runout. 2. do not use the bearing seat, usually how to refuel?.Are there any field installation drawings or data on thrust bearings?. Thanks a million!: Hello, I have sent a message to your mailbox, I hope you can help! Have problems you can contact us directly, Beijing Sheng Yi Huitian Electromechanical Equipment Co. Ltd

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.
