To make a ships-diesel engine perform at its best, allpa offers among other things cv-joint shafts, flexible shock-absorbing motor mounts, propeller-shafts in numerous sizes, high quality inner bearings and outer bearings.
An A-flex cv-joint shaft reduces the noise production and vibration of the engine by 90%. This type of propulsion simplifies the engine-gearbox installation. The alignment procedure is made simpler, too, thanks to the self-aligning propeller shaft.Several types of cv-joint shafts are available for engines up to 50HP. As well as for engines of 80, 90, 170, 250 en 350HP.
We supply bearings of different types, such as self-lubricating bearings, self-aligning shaft logs, water lubricated inner- and outer-bearings, fixed inner-bearings made of bronze or neoprene. The bearings are fit for propeller-shafts of 25 to 60mm. Accessories are also available, like counter-flanges, propeller-shafts, propeller-shaft struts, bearing sleeves in every size.
The allpa flexible engine mount is fit for engines up to 350HP, needs little vertical space and has a relatively large absorption-distance. The mounts and shock absorbers receive the vibration of the motor very well and they make different engine line-ups possible, e.g. with or without thrust bearing, when height in the engine-room is limited. In this online catalogue the precise information is available for the maximum weight per engine mount.
allpa supplies propeller-shafts in various sizes of length and diameter. Propeller shafts always come with propeller nuts, zinc anode and peg. allpa propeller nuts with zinc anode are always supplied with a lock washer.
