Product Specifications:

cylindrical roller bearing , Cylindrical roller and race for line contact bearing. Load capacity is big, mainly bear radial load .

1. Friction coefficient is small, suitable for high speed limit speed close to deep groove ball bearings

2.N and NU type axial movement, can adapt to shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing

3. On the shaft or hole of the processing and the demand is higher, bearing outer axis relative deflection after installation to be kept under strict control, so as not to cause contact stress concentration

4. Inner ring or outer ring separable, easy to install and remove

Product Applications:

Cylindrical Roller Bearing Application Flied:Rolling Mills,Crusher,Mining

Metallurgy Petroleum,Chemical Industry,Engineering Machinery,Port,Oil,Gas,

Wind,Agriculture,Lathe,CNC,Steel Works,Electrical Machinery,Axle/Limber,

Tractor,Autocar,Crude Oil Engine and so on.

NJ 303 E,Cylindrical Roller Bearing Used Mower Wheels Bearings

Q: How much is the shaft shoulder height of the 81105 cylindrical roller bearings with inner diameter 25mm?: The shoulder height (diameter) shall be smaller than the big diameter of the bearing (less than 42), mainly for easy unloading.

Q: How to check the thrust cylindrical roller bearings?: This data is the minimum axial load, not the maximum axial 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: Double row cylindrical roller bearings how to disassemble?: If it is replaced, use the flame to heat it quickly under the conditions permitted! The inner ring is heated and expanded and removed rapidly; flame cutting is used directly.

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: 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: How to calculate the clearance of bearings, such as 23226 double row cylindrical roller bearings: 1, radial clearance: non preload, bearing radial load, the radial clearance of G for any angle along the radial direction, in the absence of external load relative to the outer ring inner ring from a radial eccentric limit position, move to the opposite limit position of the radial distance arithmetic mean.2, axial clearance: non preload, bearing can withstand axial load in two directions, the axial internal clearance of G: without external load, a ring relative to the other ring, from an axial limit position toward the average axial distance limit position opposite the.

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.
