Polymer Underwater Bearing Unit

ASAHI “Bearing that can be used in water” refers to Polymer Underwater Bearing Unit; ASAHI is the one and only manufacturer of this kind of bearing.
Polymer Underwater Bearing Unit is also known "high density polyethylene bearing and polymer PEEK bearing"; it is applicable to food processing machinery and medical equipment in humid environment such as disinfection, disinfectant, salt water and water. In case of high humidity or underwater circumstances, this kind of bearing unit is characterized by its excellent corrosion resistance comparing with ordinary stainless steel bearing and is more widely used than martensitic stainless steel bearing.

Features of ASAHI Polymer Underwater Bearing Unit:


1. Corrosion resistance: housing of the bearing is made of latest PEEK plastic which makes the bearing applicable in water, fluid and other corrosive medium;

2. Thermo-stability: normal performance of Asahi Polymer Underwater Bearing Unit can be assured underwater with tolerance temperature range of: - 20 - + 250, and it is characterized by its excellent adaptability in various temperature;

3. Minimum friction: wear resistance, small friction coefficient and long service life;

4. Larger loading carrying capacity: the appropriate elastoplasticity distributes thrust load on a relatively wide contact surface and hence improves loading carrying capacity of the bearing.

5. Automatic lubrication: lubricating layer is formed during operation to protect shaft from friction and injuring;

6. Simple adjustment: performance of the bearing unit does not depend on the hardness of shaft; easy treatment of shaft and easy machining of relevant component is thus ensured.

7. Small: the bearing unit is in a wall structure which is thin and light, the volume of equipment can be thus reduced.
