Oil supply Fully self-contained lubrication is achieved by using a loose oil ring. Alternatively, where bearings are lubricated by an external oil circulation system, this loose oil ring can be used to permit an emergency shutdown without damage in case an oil system failure occurs. Z-bearings can be used for marine applications, where an oil ring guide assures proper lubrication even if extreme vessel motions occur. Electrical insulation To prevent stray currents conducted by the shaft, Z-bearings can optionally be supplied electrically insulated. In this case, the spherical seat of the housing...

1) Limit dimensions of the shaft acc. DIN 31 698, form and positional tolerance and surfaces roughness acc. to DIN 31 699. 2) Standard thrust clearance is 0,6 mm. If reversible thrust loads or shock load occur, dimension b20 can be reduced by 0,3 mm. If a locating bearing (shell type B,K) is needed only for test runs, dimension b20 can be enlarged by 4 up to 6 mm. 3) If the non-locating bearing must allow larger motions (due to heat expansion or to large thrust clearances caused by the unit), dimension b21 can be enlarged. 4) The plunge cut d32 is dropped, if it is equal or smaller as the shaft...

1 // Types and dimensions of seals 1) These sizes of seals can be manufactured in floating labyrinth seal or rigid seal. All other seal sizes can only be manufactured in rigid seal. 2) Details on request. Rigid seal* (Protection IP 44) *Can be combined either with a bolt-on baffle (IP 55) or with a dust flinger (IP 54) Floating labyrinth seal with bolt-on baffle (Protection IP 55) Floating labyrinth seal with dust flinger (Protection IP 54) Special seal designs for specific applications upon request.
