Bit Holding Systems

• Available for all mining applications, from the lowest Continuous Miner, to the largest Longwall System.
• High-wear areas can be renewed by quickly replacing a sleeve.
• Bit holder and sleeve holes are induction hardened to provide extended life.
• Heat-treated alloy steel is used in the bit holders and sleeves to provide durability.

• Universal links provide 35 degrees of flex to more easily clear obstructions.
• Chain fits older machines designed for 2 5/8 inch / 67 mm pitch.
• Induction hardened pins reduce wear.

• Available in 3 1/4 and 4.1 inch / 83 and 104 mm pitch, and both can be used on JOY 10SC and 21SC shuttle cars.
• Special roller links effectively remove dirt from the journal areas to eliminate seizure of the pins in the holes.
• Dramatically lowers machine maintenance cost and improves maintenance safety.

• Designed for optimum tractive effort to provide a stable footprint for maximizing cutting.
• Treadlinks are made of high-strength heat-treated alloy steel forgings to provide durability.
• Crawler chains contain high-strength corrosion resistant, heat-treated stainless steel journal and lock pins.

• Designed to work in conjunction with the cutter drums of the continuous miner.
• Assists in transporting the cut material to the conveyor.
• Chain link assemblies are made of high-strength heat-treated alloy steel forgings to provide durability.
