Martin 4012COV Aluminum Coupling Cover
Martin 4012 Coupling Cover – Aluminum – Inch – 4″ OD – 2″ Length,
This Martin coupling cover is for use with Martin taper bushed, Quick Disconnect (QD) and stock, and finished bore roller-chain style couplings.
It is made of aluminum for corrosion resistance and minimal additional weight to the coupling, and has synthetic rubber seals to keep lubricants contained and keep contaminants out.
This coupling cover consists of two halves to facilitate installation with gaskets between the halves to help prevent lubricant leakage or debris intrusion between the halves.
Martin roller chain couplings are suitable for use in a variety of industries for applications that involve slow speeds and high torque, including conveyors, fans, blowers, pumps, motors, and gear boxes, among others.
Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other.
Most flexible couplings consist of two hubs and a middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the two shafts.
Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from one shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from one type of misalignment to another.
Flexible couplings are used in a broad range of applications, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.
Martin Sprocket & Gear manufactures power transmission and conveying products.
Martin provides tools that meet American National Standards Institute (ANSI), National Aerospace Standard (NAS), and Deutsches Institut für Normung (DIN) standards.
The company, founded in 1951, is headquartered in Arlington, TX.
