Feroball® FBK-series
Product description:
Feroball® is a special designed self lubricating spherical plain bearing for slow
moving/oscillating applications. Feroball® bearings are designed for wet or humid
situations, Feroball® bearings are also known for their specific low stick-slip limits.
Feroball® spherical bearing are available in full composite (FBA series), Steel or
Stainless Steel in combination with composite (FBT, FBS and FBX series) and
spherical parts out of composite (FBK series)
Design:
The Feroball® FBK series is a product made of Railko NF22 (for shaft Ø16 and Ø20
mm) and Feroform PR18 (for shaft Ø25 and bigger). Although Feroball® bearings are
a low stick-slip design, Feroball® FBK bearings have a higher coefficient of friction
than Feroball FBT series. Feroball® FBK bearings are special designed for application
where the housing has already a spherical shape.
Feroball® FBK series are cut into two parts before turning, therefore the product fits
seamlessly.
Standard materials
• Ball:
Feroform PR18
Standard sizes
Feroball® FBK-series are the standard range of the Feroball® spherical plain bearing
design. The Feroball® FBK are standard available for shaft sizes of Ø16 up to Ø200

Grease groves
Although Feroball® FBK-series bearing are a self lubricating design, we standard
supply the bearings with a grease grove. Feroball® FBK-series bearings are standard
produced for shafts in the range from Ø16 up to Ø200 mm. On request grease groves
can be produced in diameters above Ø30mm ID. All groves come with 2 grease holes.
Specials
For special applications special changes can be made to the Feroball® concept.
Possible changes are for example:
• Different and bigger diameters
• Different wideness
• Without grease grove and holes
Kühne Industrie BV has designed many changes to fit Feroball® bearings in existing
applications or on design request.
