    Labyrinth seal (bearing seal)

    Dears: In fact for design of a labyrinth seal in a water pump I search for the amount of gap (radial or axial) between rotary and stationary parts in an application with 1500 rpm and oil(SAE 30)sealing(bearing lubrication. can you help me? is this type of sealing useful?

    Labyrinth seal (bearing seal)

    Hi All Dears: I would like to know some detalis about Labyrinth seals in water pumps.How much is the radial gap (between housing and seal)in this type of sealing?whether this type seals is prefered to contact seals for oil lubrication?

    taper roller bearings Spacer

    For creating clearance between two taper roller bearing (face to face), Shall we use spacer ring bigger/smaller than distance between two outer rings of bearings? For example if we have 35mm distance between two outer rings, shall we use 35.05mm or 34.95mm spacer ring??

    change C3 clrearance to CN (by change the bearing seat )

    Dear Hippo41, thanks for your help. you Can't believe that 6413 C3 are not available, but believe because I live in a conutry that cant find C3. Here in markets there are various kinds of bearings with different marks that may be many of those counterfeit and we can’t trust to those. I have...

    radial clearance in bearing

    We have a centrifugal water pump, 2900 rpm speed. The water temperature is 20-30 centigrade degree. In original design (KSB Germany) this pump has two 6413 C3 bearing with 0.023-0.043 mm radial clearance. Now we can't find C3 bearing. Can we use CN (0.008-.0.028 mm radial clearance) bearing by...

    taper roller bearing (spacer ring)

    We have a high pressure pump MC200/4 wich have been bulit by Sulzer company. Now we have a problem with the reparing of its discharge side bearings wich are 2 taper roller bearing 31319(face to face). As you know a ring should be placed between them(sacer ring).The distance between outer rings...
