Tsubaki engineers, in applying knowledge garnered from racing, have developed advanced engineering and production methods to develop chains that can endure high impact, extreme heat and sustained high speed. Tsubaki doesn’t make special megabuck racing chains for racers. Off-the-shelf Tsubaki O-ring chain is the choice of champions for its proven durability and strength, assuring you of superior value and performance.
QR SERIES
Critical areas are heat treated and shot peened for greater durability
Each chain is prestressed and pre-stretched at factory to minimize initial stretching
Economical, high-quality solid roller chain
Recommended exclusively for machines originally equipped with non-O-ring chain
OMEGA S SERIES
Each chain is prestressed and pre-stretched at the factory to minimize initial stretching
Features select alloy steel with vital components heat treated, then shot peened
Power-robbing friction and drag normally associated with O-ring chain is virtually eliminated with shouldered and projected bushing construction
