“Bridgestone... Serving Society with Superior Quality”
BRIDGESTONE, THE RUBBER TRACK EXPERT
It was Bridgestone engineers who pioneered the Rubber Track for excavators in the 1970’s. Construction machinery manufacturers all over the world have adopted our Rubber Tracks on their machines. Bridgestone is the world’s largest manufacturer of Rubber Tracks. By drawing on the group’s extensive R&D, design and testing resources and combining this with our vast experience of tracked vehicles, Bridgestone Rubber Tracks for excavators meet the most demanding specifications in the industry.
Using the latest Bridgestone technology Tri-Tech has improved durability, reliability and performance. Behind these three improvements Tri-Tech incorporates several new technical features including Pro-Edge, Tapered Core Metals, an Interlocking system, Anti-rust Steel Cord and Block Tread Pattern.
Three improvements using the latest technologies from Bridgestone
Bridgestone developed innovative Pro-Edge technology to minimize edge-cut damage. Pro-Edge technology is based on the combination of a rounded shape core metal edge design to avoid the build-up of stress concentrations and additional rubber volume on both inner and outer sides to make the track more durable.
Bridgestone has reduced the vertical movement of the track rollers by adopting an advanced tapered protrusion technology. This results in improved ride comfort without the need of additional material.
A newly developed blocked type tread pattern reduces lateral slippage, allows efficient mud release and provides good ride comfort.
Bridgestone uses an interlocking design to reduce de-tracking. By interlocking adjacent core metals the track benefits from greater lateral stiffness.
Minimizing deterioration caused by rust. Even when moisture or mud penetrate from external cuts, steel cord tensile strength is maintained for longer with Bridgestone’s Anti-Rust Steel Cord.
1. IMPROVED DURABILITY
Bridgestone’s Pro-Edge technology is now well accepted by many customers and proved in the market. The benefits of Pro-Edge are also proved by Bridgestone’s internal testing and by FEM analysis.

2. IMPROVED RELIABILITY
Interlocking technologies have become common features in Bridgestone short pitch tracks. Positive market feedback, successful supply history and Bridgestone’s internal testing all confirm the benefits of interlocking technologies.
The following testing was carried out at Bridgestone’s proving ground in Tochigi Japan. Even in loose tension conditions (sag=45mm) interlocking tracks did not de-track.
Salt bath testing carried out over 7 days has proved over 41% improvement in performance compared with standard steel cord.
3. IMPROVED PERFORMANCE
Better ride comfort
Data obtained by FEM analysis and field testing clearly shows a reduction in vibration using tapered core metals. This brings greater ride comfort to the operator.
Thanks to the segmented block pattern, lateral slippage common when working on slopes is reduced. Operating therefore becomes safer.
Rail type tracks are for machines which use an outside running roller which runs on the outer flat surface of the track (not on top of the core metals). There are two types of rail track depending on your machine. Check with your Bridgestone representative which type is compatible with your machine.
Tapered Core Metal: Better ride comfort
Track size is indicated by a size numbering system consisting of 5 elements. This part number is normally vulcanized on the inner surface of the track.
