NSK will heat resistance and strength in the rolling bearing raised to use on the component such as degree. Through adding polyvinyl resin in fibrous material, with the strengthening polylactic acid resin, tensile strength and rigidity than higher. In addition, through to cooperate to use improver and won the assembly required softness.

The original biodegradable plastics in 120 ℃ can quickly degradation or dissolution under melting. And new development of plastic is different, even in 120 ℃ environment placed 1000 hours and almost won't, because this can actually used the deteriorating component. Melting point about 200 ℃, the highest working temperature of 100 ℃. The company says, will new development of plastic placed in the soil, in can be decomposed 180 days above 60%.

The company developed in keeping the device and seals used this plastic manufacturing "highly environmentally friendly rolling bearing". Filled with internal lubricating oil using biodegradation "GREEN EXCELLA NS7 lubricant", through the shape of the outer contrive internal realize low torque. This bearing at 100 ℃ under the environment of 10,000 RPM, 5,000 hours of durability test, confirm the material has excellent durability.
