Why choose one over the other? 81X is at the heart of every modern sawmill operation. This versatile chain is available in many grades of quality. At Tsubaki we are proud to offer three tiered levels of 81X quality:

81X Lambda:
Features
Oil impregnated sintered metal bushing for lube-free operation.
  • 7-14 times longer life than unlubricated chain
  • Same precision of material, heat treatment, fabrication and assembly as 81X Premium.


Applications
Multi-strand Timed Conveyors:
  • Drop Sorter
  • Trimmer
  • Scanner
  • Any application where contamination of the product must be avoided


Note that 81X Lambda chain has a slighter wider profile than Premium or Econo.
