Feroball® FBX-series

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) and Steel or Stainless Steel (FBT and FBX series).

Design:

The Feroball® FBX series is a product made of Feroform PR18 and Stainless Steel (1.4404). This makes the Feroball® FBX a superior corrosion resistance spherical bearing. Although Feroball® bearings are a low stick-slip design, Feroball® FBX bearings have a higher coefficient of friction than Feroball FBT series.

Standard materials

• Inner ring: Stainless Steel 316L (1.4404)
• Outer ring: Feroform PR18

Standard sizes

Feroball® FBX-series are the standard range of the Feroball® spherical plain bearing design. The Feroball® FBX are only available as ND-series (Normal Duty design) and start with a shaft size of Ø20 going up to Ø200 mm.

Grease groves

Although Feroball® FBX-series bearing are a self lubricating design, it is possible to grease the bearings to increase lifetime. Feroball® FBX-series bearings are standard produced in the range Ø20 up to Ø200 without grease groves. On request grease groves can be produced. All groves come with three grease holes.

Specials

For special applications special changes can be made to the Feroball® concept. Kuhne Industrie BV has designed many changes to fit Feroball® bearings in existing applications or on design request to avoid thermal expansions and other combined radial and longitudinal movements.

Lifetime Calculation

To prevent bearings from failure it is important to choose the right bearing design. Kuhne Industrie BV can advise for design and calculate life time prediction as an extra service to the Feroball® products.
