Types of Shaft Collars
A shaft collar is a simple machine component that plays a critical role in power transmission. It is typically found in gearboxes and motors, and serves as a bearing face, mechanical stop, and locating component. Its simple design makes it easy to install and use. Its various functions make it a useful machine part for many applications.
Set screw shaft collars
Set screw shaft collars are used in many different applications and can be manufactured in a variety of materials. Typical materials include carbon steel, stainless steel, platinum, silver, nylon, polysulphone, PTFE, and PVC. Collars are easy to install and adjust. A variety of secondary services are available, including internal forming, chroming, and passivating.
Set screw shaft collars come in different styles, including standard collars, quick-release collars, split collars, and threaded collars. They can be purchased in standard and metric sizes, and are available in a variety of finishes. Standard collars are available in steel and stainless steel and have a zinc plated or black oxide finish.
Set screw shaft collars are an excellent choice for holding power transmission components in place and limiting shaft movement. They are held in place by a set screw that digs into the shaft material, providing holding power. They are available in both 303 and 316 Stainless Steel, making them a reliable and efficient choice for a variety of applications.
Clamping-style shaft collars
Clamp-style shaft collars are a versatile alternative to set-screw collars. They eliminate the problems associated with the set-screw collar, such as the possibility of shaft damage. They also lock in place by compressing against the shaft. This method distributes the force on the collar and shaft evenly, creating a stronger holding power.
Shaft collars are manufactured by many companies. You can buy them in-store or online, but it is important to buy from a reputable manufacturer. Many counterfeit collars endanger the life of your machine. Choosing a quality collar will help you avoid costly and time-consuming machine breakdowns.
Clamping-style shaft collars come in a variety of sizes and types. Some of them have a hex or D-bore. Some have circular grooves to assist with installation. They can be found in bore sizes from 1/4″ to one inch. They are often used for mounting gears, sprockets, and bearings.
Two-piece clamp collars are an excellent choice for high-load applications. They have improved clamping force and impressive holding power, and can be easily installed without major disassembly. Two-piece clamp collars can also be designed with a keyway to secure a keyed shaft. There are also special double-wide clamp collars for high axial load applications.
Another type of shaft collar is the quick clamping collar. It is an excellent choice for applications where you want to make frequent setup and adjustments. It allows for easy adjustments with minimal tools. Quick clamping collars feature a cam lever and a clamping lever. They are convenient and highly flexible, making them ideal for use in many industries.
Single split shaft collars
A single split shaft collar is designed to fit one shaft and eliminate two pieces. This makes installation and disassembly easy, reducing labor and downtime. It also uses a full seating torque of the set screws to distribute forces evenly around the shaft circumference, providing stronger holding power. It can be used on a wide range of rotating equipment.
Single split shaft collars are available from CZPT Products. They are a common, high-quality way to secure a shaft. They wrap around the shaft for a secure and tight fit. They are also a versatile option that can be easily removed. These collars can be used on both hard and soft standard round shafts. They provide superior grip compared to solid collars, provide tremendous axial force, and minimize shaft distortion.
Single split shaft collars are one of the many types of bearing shaft locking collars. They are made of EN8 steel, and come with a locking setscrew. This makes installing the collar quick and easy. The collar is available in many sizes, including small, medium, and large. If you do not find the right fit, you can also have one custom-made.
These collars are commonly used for mounting fixtures, sensors, and other assemblies. They are available in two-piece and one-piece styles, and have higher holding power than standard shaft collars. They are available in a wide range of materials, including 1215 lead-free steel, 303 stainless steel, and lightweight 2024 aluminum.
Aluminum shaft collars
The CZPT company produces Aluminum shaft collars for a variety of applications. These shaft collars feature a proprietary manufacturing process to ensure accurate face-to-bore perpendicularity. This helps to improve clamping forces and installation fit. Each collar features the CZPT name stamped on it, and the collar is finished with a black oxide process to achieve a fine glossy finish. The shaft collars are available in a variety of bore sizes and styles, and can be ordered in single or two-piece styles. Additionally, they are manufactured with a high-grade forged screw, which ensures the highest quality.
Aluminum shaft collars can be customized to fit your needs. Several accessories can be added to the shaft collar, such as steel mending plates. Those who need extra load capacity can select a keyed shaft collar. They are also available in lightweight styles. These shaft collars are easy to install and disassemble, and are made from two-piece aluminum for ease of installation.
Choosing the right shaft collar material is critical to the success of your application. You should consider steel, stainless steel, or aluminum for the best corrosion resistance. Steel is stronger and offers better holding power, while aluminum offers a lower weight and a favorable strength-to-weight ratio. When selecting shaft collars, it is important to take into consideration the corrosion resistance of each material. For example, carbon steel shaft collars will not be as corrosion resistant as aluminum shaft collars, but they are lighter and have a good hold power.
Carbon steel shaft collars
Carbon steel shaft collars are a versatile solution to holding bearings in place. They are available in a range of diameters and styles to meet your application needs. They can be used for many different applications, from aerospace and military applications to marine and automotive applications. These collars are available in a variety of materials, including carbon steel, aluminum, and stainless steel.
Carbon steel shaft collars are a cost-effective alternative to stainless steel shaft collars. CZPT manufactures lead-free carbon steel shaft collars, and they are also available with RoHS-compliant yellow zinc plating. Zinc plating is less expensive than stainless steel and is an excellent anti-corrosive option. CZPT yellow zinc collars are plated by a trivalent process rather than a non-compliant hexavalent process.
Shaft collars are available in both metric and inch bore sizes. They can be used for a variety of applications and are typically available in sizes ranging from 1/4″ to three inches. They are also available with metric screws in a range of sizes, which are useful for retrofitting equipment.
Shaft collars are available in a variety of materials, including carbon steel, 303 stainless steel, and aluminum. Some options feature threads and can be welded or bolted to shafts. For more advanced applications, aluminum threaded shaft collars can be used. They are often used for mounting sensors, fixtures, and other assemblies. They come in several styles, such as double-wide, heavy-duty, and threaded.
Hinge shaft collars
Hinge shaft collars are fastening devices that secure shafts or axles. They come in a wide range of sizes, shapes, and materials. These collars can be used in a wide range of applications, including non-rotary applications. They can be manufactured in stainless steel, 1018 steel, aluminum, and brass.
Shaft collars are simple to use but can perform a variety of functions. Their primary functions include holding components in place, locating components on a shaft, and establishing attachment between the shaft and another component. To choose the right collars for a specific application, designers should consider the design, style, materials, bore size, and geometry of the shaft. They should also consider any limitations or requirements associated with the application.
Hinge shaft collars are available in round and square bores. They are most commonly used in agricultural applications. Their size makes them easy to install, and their design makes them suitable for both large and small shafts. They are also used in situations where shafts are not easily accessible. Some types of shaft collars feature flat surfaces, which are great for mounting applications and splitting hubs.
Heavy duty shaft collars are also available. These collars have larger outer diameters, wider bores, and larger screw diameters. They are manufactured from lead-free steel with a proprietary black oxide finish.
