What are Mounted Bearings
Mounted bearings are machine components that support rotating or linear motion. They are mounted onto a shaft or surface and help to reduce friction and wear between the moving parts of a machine. Mounted bearings come in various shapes and sizes, and they can be used for different types of machines, including conveyor systems, food processing equipment, and packaging machinery.
Mounted bearings typically come with a housing that provides support and protection for the bearing. The housing is a stationary part of the machine and is usually made from materials such as cast iron, stainless steel, or plastic. The housing can be designed to accommodate different types of bearings, such as ball bearings, roller bearings, or needle bearings.
Mounted bearings work by supporting and facilitating rotational or linear motion in a machine. The bearing is the component that directly supports the shaft, while the housing provides protection for the bearing and helps to keep it in place. When the machine is in operation, the bearing rotates or moves linearly, and the housing helps to keep it aligned and prevent it from coming loose.
Types of Mounted Bearings
There are several types of mounted bearings and housings, each designed to meet different application requirements, most importantly pillow block bearings, flange bearings, take-up bearings, and insert bearings.
Pillow Block Bearings
Pillow block bearings, also known as plummer blocks, are a type of mounted bearing designed to provide support for a rotating shaft. The name "pillow block" comes from their shape, which resembles a pillow with a flat base and a rounded top. Pillow block bearings consist of a housing and an insert bearing, which is designed to fit inside the housing. The housing is usually made of cast iron, but can also be made from other materials such as stainless steel or thermoplastic.
Pillow block bearings are commonly used in applications such as conveyor systems, agricultural equipment, and industrial machinery. They are known for their ease of installation and maintenance, as well as their ability to support heavy loads and operate at high speeds. When selecting a pillow block bearing, it's important to consider factors such as load capacity, speed rating, and environmental conditions.
Flange bearings, also known as flanged mounted bearings, are similar to pillow block bearings in that they provide support for a rotating shaft. However, they differ in shape and mounting options. Flange bearings have a flat housing with a protruding flange on one or both sides, which can be bolted to a mounting surface. The insert bearing is designed to fit inside the housing and is secured in place with set screws or a locking collar.
Flange bearings are commonly used in applications where space is limited or where a shaft needs to be supported at a specific location. They are often used in conveyor systems, printing presses, and medical equipment. When selecting a flange bearing, it's important to consider factors such as load capacity, speed rating, and mounting options.
Take-up bearings, also known as frame-mounted bearings, are designed to provide support for a rotating shaft while allowing for easy adjustment of the shaft's position. Take-up bearings consist of a housing with a take-up frame that can be adjusted to tighten or loosen the belt or chain that is driving the shaft. The insert bearing is designed to fit inside the housing and is secured in place with set screws or a locking collar.
Take-up bearings are commonly used in applications such as conveyor systems, packaging equipment, and textile machinery. They are known for their ability to provide easy shaft adjustment and their resistance to harsh environmental conditions. When selecting a take-up bearing, it's important to consider factors such as load capacity, speed rating, and adjustment range.
Insert bearings, also known as radial insert ball bearings or wide inner ring bearings, are designed to be mounted on a shaft and inserted into a housing. The insert bearing has an extended inner ring that provides additional support for the shaft and allows for easy mounting and dismounting. The housing can be made from a variety of materials, including cast iron, stainless steel, or thermoplastic.
Insert bearings are commonly used in applications such as agricultural equipment, food processing machinery, and HVAC systems. They are known for their ease of installation and maintenance, as well as their ability to handle radial and axial loads.
