【 Jiaxing bearing 】 The distinction between cylindrical bearings and needle roller bearing principle

Jiaxing bearing group sales co. , LTD. , is the spot sales center of jiaxing bearing factory, specializing in HRB bearings, application in production design and related machinery has a wealth of technical experience, today we are together and we learn to distinguish between principle of cylindrical bearings and needle roller bearings. The distinction between cylindrical bearings and needle roller bearing principle: look from the shape, needle roller and the difference between standard has two kinds: the first is the ratio of 2. 5 as the cut-off point. The second is based on proportional 4 standard. In terms of stress, needle don't bear axial force ( Needle of end face grinding, if the contact and shoulder, the friction is very big) And the roller, if take the shoulder is can withstand the axial force, of course not too big, principle is no more than 1/10 of the radial force. From the application point of view, needle is mainly used in place with limited space, so the car, motorcycle, textile machinery, widely used. And inner ring is equipped with the needle, namely if the hardness of shaft, roughness in conformity with the requirements, such as can not inner ring ( Space is limited) The degree of processing, but if the shaft is lower, or more soft, you will need to match inner ring raceway. And the floating roller are often used to support shaft, to absorb axial expansion amount. Four columns on roller with the more, mainly is the roller bearing capacity is very big.
