G8 Series Heavy Duty Chains and Sprockets

Tsubaki’s G8 Series is the rebirth of the drive chain with improved quality and performance compared to its predecessors. Heavy Duty Drive Chain has a higher maximum allowable load (MAL) and tensile strength than standard RS roller chain.

• Super Chain has 5-10% higher maximum allowable load than the G7 series.

• Super-H Chain has 20% higher maximum allowable load than the G7 series.

• RS-HT Chain has twice the wear life of G7 series and offers slip fit connecting links.

Heavy Duty chains offer many benefits

1) Saves space.

For example, RS80-SUP-H-1 Super-H Chain has the same maximum allowable load limit as RS80-2-RP double strand chain. This means a single strand of Super-H Chain can replace the need of double strands. Furthermore, a single strand chain requires a smaller sprocket compared to that of a double strand chain. By using a smaller chain and sprocket, more compact parts are used, saving space in your operation.

2) Saves Money

Using smaller chains and sprockets can reduce costs. Below chart is a cost comparison between Super-H Chain and Double Strand RS Roller Chain – reduced cost by 50%!

Combat High Speed and Accelerated Elongation with Tsubaki’s Titan Chain

Issue:

An end user’s re-saw outfeed was causing frequent unplanned downtime. The serpentine application was using a competitor’s 80 riveted chain that runs through a series of idler sprockets with a lot of articulation running consistently at high speed with no room for adjustment. Lubrication was difficult due to its location, causing accelerated elongation and chain frequently jumping off the sprockets as it elongated.  The entire chain run had to be replaced every four (4) months; but more significantly it caused 5-10 unplanned downtimes per week. This included 15 minutes of maintenance time per incident to do a “quick fix” and get the line running again at a rate of $100/minute of maintenance cost to the mill.

Tsubaki Solution:

To combat the issue of high speed, accelerated elongation and lubrication, Tsubaki recommended 80 Titan chain. Titan’s special coated pins provide extra hard, low friction surface limiting the wear between the pin and bushing area, significantly extending wear life and providing robust performance especially in high-speed applications. In addition, Tsubaki’s Performax bushings with lube grooves on the inner surface retain lubrication at the point of contact, further increasing wear life.

Cost Savings:

Tsubaki’s Titan Chain lasted over a year compared to the competitor’s four (4) months and eliminated the unplanned downtimes. With a higher degree of reliability, Tsubaki helped the customer save $174,775.77.
