  • The use of self-lubricating engineering plastic sleeves eliminates the need for lubrication.
  • Excellent wear resistance ensures long life.
  • Since no metal dust is generated from contact between the engineering plastic parts and the steel parts, your environment and equipment are kept clean. A When using the stainless steel chain series, corrosion resistance is also increased.
  • The use of engineering plastic rollers results in significant weight reduction compared to all stainless steel chain (small "S" roller type: 15% less, oversize "R" roller type: 40% less).
  • With the use of engineering plastic sleeves and rollers, quiet operation is
  • RS40, RS50 and RS60 with plastic sleeves are available upon request. Contact U.S. Tsubaki for details.
