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 Econo:
Features
An economical version that meets the general need of non-timed sawmill applications.

Applications
Non-Timed Conveyors:
  • Transfers


81X Premium:
Features
Building upon the strength of the 81X design, Premium offers better performance on multi-strand timed conveyors where relative length tolerance and rate of stretch is critical.
  • Improved material & heat treatment
  • Precision and consistency of fabrication & assembly


Applications
Multi-strand Timed Conveyors:
  • Scanner
  • Trimmer
  • Drop Sorter


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.
