Tsubaki of Canada Limited - Extra Heavy Duty Offset Sidebar Mill Chains

One of the backbones of forestry operations, Welded Steel Chain operates in some of the most demanding applications. The inherent design provides high tensile and fatigue strenght. This brute of a chain must withstand high shock loading, provide resistance to abrasive material and operate in extreme temperatures and climates. Building upon the basic design, Tsubaki's Mill Chain Sidebars and Barrels are shot peened for additional fatigue strenght, Pins are precision fit for a superior press fit into side bar.

Notes:
1/ WR: Offset sidebar style, with heat treated rivets.
2/ WH: Offset sidebar series, with all parts heat treated.
3/ WRXHD: Offset sidebar extra heavy duty series, with heat-treated rivets.
4/ WHXHD: Offset sidebar extra heavy duty series, with all parts heat treated.
5/ If extended wear life pin is required Tsubaki can supply IBR or IBRS as an option for all chain on this page.
6/ Riveted type connecting pins are supplied as standard cottered upon request.
