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: 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?: 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: 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. The latter is mainly used as a precision screw shaft for the radial motion and axial runout requirements are very strict, generally used when they are two back-to-back, when pre tightening have strict requirements, general requirements for the radial motion and axial runout should not exceed 5 per thousand mm.

Q: Why cylindrical roller bearings can not bear axial load?.: Bearing bearing axial force or radial force is determined by the structure of the bearing, thrust ball bearings are also called plane bearings, which are mainly used to bear axial force; cylindrical roller bearings can bear radial forces and are not suitable to bear axial force.

Q: For example, NU, NJ, N, RNU, NUP, NF, NO, NN, RN, what do you mean, who can tell me about that hero?: NN double row cylindrical roller bearing inner ring gear side no outer wallRN no outer ring type N cylindrical roller bearing

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!: Generally speaking, the reduction of the limit speed is positive. As for radial loads, the two bearings are not multiplied by 2. on the carrying capacity of a single bearing, and the coefficient is different for each company.

Q: Cylindrical roller bearings, in the grease after the operation for a short period of time, the grease was thrown out (thrown to the end cap), resulting in roller and raceway between the lack of grease, lubrication poor. Decomposition found that the roller has round circumferential friction marks, but also on the roll, but compared to the roller is very slight. And there are relatively sound bearings, abnormal sound.Is this phenomenon normal? What if it doesn't work? What was the reason? What's the solution? StopThanks for your help!Assuming the grease is no problem, viscosity, consistency, selection is no problem If exclusion is the problem of grease, what other reasons can this be the case? ?: Grease over dry, thin will affect the effect, but also with the brand of grease is also related, you can try several kinds of grease, to see what kind of effect is bestChangshou City Kazakhstan axis electrical and mechanical materials trade, we are agents of a variety of well-known bearings

Q: Full use roller bearings: The FAG space division has also been involved in the development of bearings and other NTN precision components for Airbus wide body passenger aircraft A380 engines. The fuel efficient Boeing 787 aircraft reduces consumption by 20% compared to similar NACHI aircraft fuels, thanks to its improved aerodynamics, better operating systems and lighter materials. From the general electric KOYO GEnx engine and the Trent 1000 engine Rolls-Royce also play a role in ensuring that the airplane plays a key role more fuel-efficient. This high performance, lighter weight engine bearing support also plays a key role in the engine. FAG Aerospace entered the concept of bearing development, the engine as early as 2005. TIMKEN bearings, China's general agent, the first prototype manufactured bearings are available in 2006 to provide general electric and Rolls-Royce, FAG rolling bearing device design factors. The first engine test operation, which took place in the fall of 2006, achieved very positive results. The civil aviation authority's approval process for the two engines will be completed by the end of 2007.. In the summer of 2008, the first batch of FAG bearings was delivered to the airline. The main production base for the FAG China production base in Shanghai and INA roller bearing Chinese sales center, as well as Germany, Canada, Sweden SKF bearing China general agent of American Timken FAG office production base. The key role of space rolling bearing FAG in Rawls Royce and general electric engine plays, FAG bearing supply of Boeing 787 aircraft, Japan NMB bearings, the two engines for the new long haul aircraft rely on Aerospace Corporation of FAG rolling bearing

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: Thrust cylindrical roller bearings, the main use?: Our factory uses the bearings of Changzhou Enke Bearing Co., Ltd., they have many kinds of bearings and meet various demands.
