Double row cylindrical roller bearings
The rollers of the double row cylindrical roller bearing are usually guided by two flanges of a ring.
Because this assembly part composed of cage, roller and guide ring can be separated from another
ring, the cylindrical roller bearing belongs to separable bearing. This type of bearing can be easily
mounted and dismounted. Its advantages are obvious especially when there is interference fits
between the inner, outer ring and the axis, housing.
This bearing is usually subjected to radial load, only the single-row bearing with inner& outer rings
flanges.
- NN double row cylindrical roller bearings
This kind of bearings with inner rid, no outer rid.This assembly part can be separated from another ring, and they have larger radial load capacity than other single row cylindrical roller bearings with the same size, but the axial or housing is free axial displacement, so this kind of bearings can only bear the axial load.
★ Product Features:
The rollers of the cylindrical roller bearing are usually guided by two flanges of a ring.
Because this assembly part composed of cage, roller and guide ring can be separated from
another ring, the cylindrical roller bearing belongs to separable bearing. This type of bearing
can be easily mounted and dismounted. Its advantages are obvious especially when there is
interference fits between the inner, outer ring and the axis, housing.
This bearing is usually subjected to radial load, only the single-row bearing with inner& outer
rings flanges can bear small steady axial load or great intermittent axial load. It has a high
requirement on the processing of the fitting parts such as axis and housing bore, etc.
★Product Application:
Cylindrical roller bearings are mainly used for:
- Iron and steel metallurgical industry
- medium and large motor
- generator
- combustion engines
- gas tuibine
- machine tool spindle
- speed reducer
- loading and unloading machinery and all kinds of industrial machinery
Double Row Cylindrical Roller Bearings Catalogue
- Q:Attention problems of cylindrical roller bearings
- 1. The installation of bearings must be carried out in a dry, clean environment. Before installation, the machined surface of the shaft and shell, the shoulder end, the groove and the joint surface shall be carefully inspected. All mating surfaces must be carefully cleaned and removed, and the cast surface must be clean. 2, before the installation of bearings, should be cleaned with gasoline or kerosene, dry after use, and ensure good lubrication, bearings generally grease lubrication, oil lubrication can also be used. Grease lubrication, grease, anti rust, extreme pressure and other excellent greases should be used. Grease filling capacity for bearings and bearing box volume of 30%-60%, should not be too much. Double row tapered roller bearing and water pump shaft bearing with sealing structure have been filled with grease, which can be used directly by users and can not be cleaned again. 3, bearing installation, must be applied equally in the circumference of ferrule end face pressure to press into the ring, and may not directly tap bearing end face to the top tool, so as not to damage the bearing. Small amount of interference in the case, at room temperature can be used to suppress sleeve bearing ring face, beating with a hammer sleeve, the sleeve will be pressed into the ring balance. If installed in large quantities, use hydraulic press. When pressing, the outer end surface of the outer ring and the outer shoulder of the shell face shall be ensured, and the inner ring end face is tightly pressed with the shoulder end of the shaft platform, and no gap is allowed.
- Q:What kind of material is used for cylindrical roller bearings?
- What's the material? The question is not good enough to answer? Usually bearing steel. And stainless steel, plastic. Carbon steel, iron, ceramics, etc.
- Q:Can cylindrical roller bearings bear high temperature?
- Bearing is not high temperature grease is not high temperature, a grease temperature does not exceed 120 degrees, high temperature will lead to bearing lubrication performance, unable to work, in fact, the bearing itself can be high temperature resistant.
- Q:Can the Nu and N type NJ NUP cylindrical roller bearings bear axial force?
- The answer upstairs is clear. Such bearings can not be designed with axial force. In use, the inner and outer rings of the bearing can have larger axial displacement, and the aim is to compensate the length change caused by the rotating part of the two bearing due to the temperature rise.
- 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!
- In general, this kind of bearing does not use the bearing seat
- Q:How are the twin row cylindrical roller bearings classified?
- The NN0000K type conical bore double row cylindrical roller bearingThis kind of bearing is compact in structure and bears little deformation under load, so it is suitable for the support of spindle of machine tool. The inner bore of the bearing is taper, and the radial clearance of the bearing can be adjusted slightly.This kind of bearing with no outer wall, so you can install the outer ring and the inner ring assembly respectively (with roller and cage), does not limit the axial displacement of the shaft or shell, cylindrical roller bearing with the same radial size is compared, can bear larger radial load.
- Q:What is the limit speed and rated dynamic load of NSK full M40-19g cylindrical roller bearings, HTF?
- NSK bearing type suffix solution of NSK bearing type by the basic code, prefix and post code, the basic code bearing series (including type) diameter and contact angle; pre code specific bearing; post code structure shape, bearing size, material, seal, retainer, clearance, heat tolerance processing, lubrication, change and other technical requirements, in addition to the basic code added after bearing code. NSK bearing model prefix F - deep groove ball bearing with flange outer ring (for D less than 10 mm), for example: F605. HR - high load tapered roller bearings, for example: HR30207J. MF - Flanged, outer race, deep groove ball bearings of specified sizes (D less than 10 mm), MF52. MR - deep groove ball bearings of specific size (for D less than 10 mm), for example: MR31. NSK bearing type rear code (1) internal structure A - internal design and standard different bearings. A - angular contact ball bearings with a contact angle of 30 degrees. A5 - angular contact ball bearings with a contact angle of 25 degrees. B - angular contact ball bearings with a contact angle of 40 degrees. C - angular contact ball bearings with a contact angle of 15 degrees. C - tapered roller bearings with a contact angle of 20 degrees.
- 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: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: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).
