• Overall dimensions of self-aligning bearings are in accordance with ISO 3228 standards
• All self-aligning bearings are interchangeable with their correspondent cast iron versions
• Self-aligning bearings are equipped with stainless steel AISI 304/316 bushes
to reinforce mounting holes
• The reinforcing bushings avoid damages to the plastic Lange during screw tightening
• Only best quality glass Ibre reinforced polyamide PA FV/polypropylene PP FV
thermoplastic resins are used for the self-aligning housings
• The resins used guarantee high resistance to oxidation and
corrosion and at the same time equal the strength offered
by cast iron housings. They offer a better resistance to impact
• Polyamide PA FV resins offer maximum heat and mechanical
resistance
• Polypropylene PP FV resins offer maximum resistance to
chemical agents
• A system of waterproof seals protects the
bearing from external environment
• Protection from dust, humidity, washouts,
chemical agents
• The clip-on protection cover allows inspection
of the bearing
• Self-aligning bearings are equipped with ball bearings
featuring multipurpose sealing systems.

- Superagriseal unit. The system consists of a metallic
ring Itted with a low friction rubber sealing lip

- Superagriseal unit + centrifuging ring. The system
is further equipped with a metallic protection ring
providing a centrifugal sealing action.
•
C steel
- Superagriseal unit + rubberised centrifuging ring.
This system is used in stainless steel bearings. The upper lip of the centrifuging ring together with
the grease trapped between the base seal and the ring itself guarantees maximum sealing capacity.
• Waterproof self-aligning bearings feature seals for the protection against
external environment
• Viton rubber seals ensure maximum resistance to chemical agents
• All bearings are self-aligning, capable of compensating misalignments up to 2°
