Q:The known bearing type is 7307, how to determine the bearing seat size?

On the market there are cast bearing seat sold, divided in the upper and lower halves, you can compare the bearings to buy. In addition, the seller who sells bearing housings know which is the 7307 bearing seat and which is the 7308 bearing seat......

Q:Encountered a problem: how to measure the bearing seat insulation after generator operation?. It is said that the bearing seat must be insulated, and the insulation is not good. What harm does it have? Expert guidance please. Thanks very much。

The insulation of the bearing seat uses a measuring point of the meter to the bearing seat, and the other measuring point is facing the ground (mainly to test whether the insulating plate and the anchor bolt of the bottom of the bearing seat are correctly or damaged).The insulation of the bearing shell uses a measuring point of the meter to the bearing seat, and the other measuring point is opposite to the bearing shell (whether the insulation plate between the bearing plate and the bearing base is properly installed or damaged or not)- some units due to the lubricating oil used with insulating effect, so the insulating plate between bearing and bearing seat is not, in the process of installation without the oil car under the pump start, is unable to measure the insulation of the above two kinds, once again after turning measuring insulation is qualified.

Q:Who has the bearing size of P209 210, please?

P209 center height 54, installation hole center diameter 146, total length 190, total height 106, width 54P210 center height 57.2, installation hole center diameter 159, total length 206, total height 114. The width of 60

Q:What's the material of UCP210 bearing seat?

UCP210 bearing housings are made of ductile iron and gray cast iron;Ductile iron is used more, grey cast iron is relatively less.

Q:After casting, planing, and clamping boring, before the final assembly is the main bearing hole, with four edges of the anchor wire hole, and is often not parallel with the spindle drill, and the control is not good, there will be inclined, after assembly, solution and support holes can't match, how to do it can be done symmetrically. And to ensure that the same side of the anchor wire hole parallel to the spindle, then?Once a model, is bearing the ground plane style, has small eyes in the four hole position, through the eye, and then drilling, but there are errors!

1) after the heat treatment, the first dimensional arrangement should be made, taking into account the allowance of the machined surface, the location of the non machined surface and the location of the important screw holes;2) then draw the bottom as the base plane;3) locate the bottom with a machined surface and clamp the bore;4) clamping to the center bore as above, as a benchmark, in the boring machine by coordinate shift, accurate processing of each installation hole bottom (positioning accuracy of common boring machine could reach 0.02 0.05mm, if it is a processing center, the positioning accuracy can reach 0.005mm);5) on the boring machine, with a good bearing, installation holes and end face positioning, on the machined bottom surface to find the correct table, through coordinate displacement, processing the anchor screw hole.The above process method can guarantee the processing of qualified workpieces, but the cost of drilling holes is higher than that of using the rocker arm.

Q:What's the difference between the bearing seat and the pedestal?

The former can be bearing, but also can be said to rolling bearing, the latter refers to the sliding bearing. The bearing is used to make the axis along the circumference of the supporting shaft and operation, the conventional usage is two or more than two bearing, its role is to make the normal operation of the shaft, and the bearing seat is used to support the bearing outer ring is fixed. Bearing inner ring outer ring, just let the rotation, remain motionless, always keep consistent with the direction of transmission (such as motor running direction), and balance.

Q:Selection of tolerances for bearing housings?

It's usually like H7

Q:Deep groove ball bearing seat

Can use side open bearing seat, model is 310

Q:How can the model of stainless steel bearing seat be correct?For example, P205 iron bearing, stainless steel said that some SP205, some SSP205 said, why?And ordinary cast steel seats. What's on the model? And plastic seat and zinc alloy seat and how different?Forget predecessors eliminating! Thanks

Stainless steel, English StainlessOrdinary cast steel outer sphere is P205, so P refers to this bearing seat type, as well as T, F, FC, PA, PH and so onAdd a S, which means that the seat of stainless steel.The price of zinc alloy is K, such as KP003,I don't know much about plastics.

Q:What's the number of the bearing seat? 1511 of the line can not ah, I do not know much about this, but the bearing seat is written on 1511, with the bearings, I feel like 6309 of the ball bearings.

General bearing seat is to do their own, buy very little, most of them do not meet their own requirements.
