Durobal® Medical Bearing for Rotating Applications
Unique Bearing for Rotating Applications
- Ideal as a guide mainly in rotating applications
- Prevent metal-to-metal contact
- Low friction
- Self-lubricating for cleaner operating environments
Durobal® bearings are generally used in low load, high speed applications such as blood separators, diagnostic equipment, laboratory sample processing equipment, Magnetic Resonance Imaging (MRI) and bioreactor applications in biotech processing equipment.
Materials Specific to Healthcare & Medical
The inner and outer rings are generally made of an acetal-based material with no fillers, as fillers can cause premature failure. The cage can be made with a filler material to enhance rolling element movement and reduce friction. Turcite® A is a typical cage material. The ball bearings can be made of stainless steel, glass or ceramics. All plastic constructions are ideal in applications such as MRI scanners.
Durobal® bearings are used in a variety of medical, pharmaceutical and biotechnology devices and equipment, generally in rotating applications. They usually consist of seven parts: an outer ring, seal, inner ring, ball bearings, cage, seal and shield.
The inner and outer rings provide support against the mating hardware. The cage maintains ball separation. Seals and/or shields may be added to isolate the bearing from the external environment.
