How to choose bearings for support rolls
Thread Content
This is a heat exchanger that I’ve encountered recently and which requires sliding movement – it needs to be moved along guide rails (not very frequently). The diameter of this heat exchanger is 1100, and its total weight is 12 tons. I was wondering what considerations should be taken into account, and what equipment is needed to support this setup. I work in pressure vessel design, and this is the first time I’ve encountered such a situation; I’m not sure where to start. Thank you!
The basic code indicates the basic type, structure, and dimensions of the bearing. It consists of the bearing type code, size series code, and inner diameter code. a1: Bearing type code – Numbers or letters are used to denote different types of bearings; details can be found in the database. a2: The size series code consists of two digits. The first digit denotes the width series (radial bearings) or height series (thrust bearings), while the second digit denotes the diameter series. The dimension tables show that bearings with the same inner diameter can have different outer diameters, and bearings with the same outer diameter can have different widths (or heights), thereby meeting various requirements regarding load-bearing capacity. a3: The inner diameter code indicates the nominal inner diameter of the bearing, expressed as a number. Example: Bearing 2 32 24 2 – Type code; self-aligning roller bearing ； 32-size series code ； 24 – Inner diameter code, d=120mm; Example: Bearing 6208-2Z/P6. 6 – Type code, deep groove ball bearing ； 2-Size series code ； 08-Inner diameter code, d=40mm ； 2Z-bearings have dust covers on both end surfaces ； P6 – The tolerance grade meets the standard specification for grade 6
It is a non-standard device; the frames can be fabricated on-site, and then the number of mining wheels required can be determined based on the load.
