Introduction
250# material（HT-250） is made of cast iron based metal with special lubricants embedded. The base metal withstands high load and the solid lubricants provide for self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/lower temperature with lower speed. |
