16MM X 3″ Pin Bush Bolt Set

This type of bolt is used in machinery and mechanical systems to connect two shafts and transmit torque while accommodating misalignment between them. Here’s a description of a pin bush coupling bolt:

• Bolt: The central component of a pin bush coupling bolt is the threaded bolt itself. This bolt has threads on both ends, which allows it to be attached to the ends of two shafts. One end typically has a larger thread size, while the other end has a smaller thread size to accommodate different shaft diameters.
• Bushings: The pin bush coupling bolt includes two bushings, one on each end. These bushings are typically made of durable materials like bronze, brass, or steel. They have an inner diameter that matches the smaller threaded end of the bolt, and an outer diameter that fits into the hub or coupling element.
• Pins: A pin or dowel is inserted through holes in the bolt and bushings to secure them in place. The pins prevent the bolt and bushings from rotating independently on the shafts and ensure that torque is transmitted effectively.
• Coupling Element: The coupling element is the part of the machinery that connects to the bushings and transmits torque from one shaft to the other. It could be a rigid coupling, flexible coupling, or any other type of coupling mechanism depending on the specific application’s requirements.

Here’s how a pin bush coupling bolt typically works:

• The larger threaded end of the bolt is attached to one shaft, and the smaller threaded end is attached to the other shaft.
• The bushings are fitted onto the bolt, one on each end, and they slide over the smaller threaded portion.
• The pins are inserted through holes in the bolt to secure the bushings in place.
• The coupling element is connected to the bushings, and when one shaft rotates, torque is transmitted through the bolt to the other shaft via the coupling element.

The use of pin bush coupling bolts is common in various industrial applications, especially in machinery and equipment where misalignment between shafts can occur. These bolts help reduce wear and tear on equipment by accommodating misalignment and shock loads, thereby extending the life of the machinery.

The design and specifications of pin bush coupling bolts may vary depending on the specific machinery and its requirements, such as the level of misalignment tolerance, torque capacity, and shaft diameters.
