Conveyor chain developments
Ramsey’s experience in the manufacture of two pin silent chains for almost 100 years has helped the company to produce what is described as a superior glass bottle conveying chain. Continuous R&D efforts have resulted in the development of innovations and special production methods for 100% steel Sentry two pin chains.
Features of this equipment include guard links with fully recessed pin heads, 100% hardened alloy steel construction (no sintered metal), two pin chain joints and staked pin heads. Pre-stressed for reduced chain elongation, these chains are available in ½in pitch and 1in extended pitch designs.
According to Ramsey, Sentry two pin chains (pictured) blend time tested extended pitch assemblies, two pin joint designs and wear protected recessed pin heads to produce chains that are fully interchangeable with existing two pin chain designs and run on standard sprockets. A proprietary staking process is used to head the pins rather than the traditional method of laser welding. This design does not add extreme heat to the links and pins and means that the pins and links are the same hardness throughout. The result is a chain that wears consistently and has a longer life.
Sentry links are specially designed to allow pins to slide in and out easily, making connection considerably easier, the manufacturer reports.
