Design
Structure
CENTAFLEX-A couplings have a modular design. This design works for many industries. The main parts are strong hubs, an elastomeric arch element, and a spacer. These parts help the coupling handle misalignment. Engineers made the system to absorb vibrations and lower shock loads. The rubber inside comes in different hardness levels. This helps control how flexible it is and how well it stops vibrations.
Y&F CF-A couplings use similar engineering ideas. Their structure has high-quality rubber and metal parts. The design makes assembly and installation easy and fast. Both couplings have different setups, like adapters, flanges, and hubs. These choices let you customize the coupling for your machine.
Tip: Modular designs make maintenance faster and replacements easier.
Components
The parts of CENTAFLEX-A and Y&F CF-A couplings work together well. Each coupling has:
Hubs: These connect to shafts and give strong support.
Elastomeric arch element: This part absorbs vibrations and lets the coupling move in different ways.
Spacer: It keeps everything lined up and helps transfer torque.
A special feature is the shear disc pack. It sends torque by using friction. The elastomer is made to absorb misalignment and vibration. Careful engineering lets the couplings handle big misalignments without losing strength.
Component | Function |
|---|---|
Hubs | Connect shafts, give support |
Arch Element | Absorbs vibration, allows flexibility |
Spacer | Keeps alignment, helps transfer torque |
Y&F CF-A couplings also absorb shocks and reduce vibrations. They are a good choice because they cost less and fit well. Both couplings help protect machines and make them last longer.
Materials
Rubber Element
CENTAFLEX-A couplings have natural rubber as the main elastomer. Natural rubber makes the coupling stretchy and bendy. This rubber soaks up shakes and sudden hits really well. It helps keep machines safe from quick forces and lets them work smoothly. The rubber part also lets the coupling deal with small shaft misalignments. Because of this, the coupling works in many kinds of machines.
Y&F CF-A couplings use strong rubber for their flexible parts. This rubber is picked because it stops shaking and lasts a long time. The rubber does not wear out fast and keeps its shape. Machines with these couplings are quieter and last longer. The rubber part in both couplings means you do not need to fix them often.
Note: Good rubber parts help make machines quieter and protect important pieces inside.
Metal Parts
CENTAFLEX-A couplings use aluminum for the hubs and other metal pieces. Aluminum is light but also strong. It gives the coupling support without making it heavy. This metal does not rust and can work in hard places. Using both natural rubber and aluminum makes the coupling bendy and tough. These things help the coupling last longer and work in many jobs.
Y&F CF-A couplings use strong metal parts too. These metals give good support and help the coupling handle lots of force. The metal parts and rubber work together to soak up shocks and stop wear on machines. Both couplings use strong metals so they stay safe and are easy to take care of.
Material | CENTAFLEX-A | Y&F CF-A |
|---|---|---|
Rubber Element | Natural rubber | High-quality rubber |
Metal Parts | Aluminum | High-quality metal |
Picking these materials helps stop shaking, makes the couplings last longer, and means less fixing is needed. These things make them a good pick for many jobs.
Performance
Torque
CENTAFLEX-A and Y&F CF-A couplings give strong torque. They work well for many machines. Engineers make these couplings to handle lots of force. The force goes between the shafts that are joined. For example, the CENTAFLEX-A model CF-AR-025-0-60 is 25 mm in size. It has a torque rating of 2788 in-lbs (315 Nm). This means it can move a lot of power. It does not slip or break when working. The rubber inside gives torsional elasticity. This lets the coupling twist a little when loaded. Twisting helps protect machines from sudden shocks. Y&F CF-A couplings use this idea too. They help machines stay safe and work smoothly. Both types are good for tough jobs. They give strong and steady torque.
Tip: Torsional elasticity helps stop damage from quick starts or stops.
Vibration
Vibration can make machines wear out fast. CENTAFLEX-A and Y&F CF-A couplings use special rubber parts. These parts soak up vibrations. The rubber acts like a cushion between metal pieces. This cushion lowers noise and keeps machines quiet. It also protects sensitive parts from harm. The couplings meet DIN 7716 standards. This means they use good rubber that lasts long. Because of this, you do not need much maintenance. Operators can trust these couplings. They keep machines steady and cut down on repairs.
Misalignment
Machines can shift a little when working. Couplings need to handle these small changes. CENTAFLEX-A and Y&F CF-A couplings allow movement in three ways. These are axial, radial, and angular. This flexibility helps them fit many machines and setups.
The table below shows misalignment tolerances for CENTAFLEX-A couplings:
Misalignment Type | Permissible Tolerance |
|---|---|
Axial | ±1.0 mm |
Radial | 0.5 mm |
Angular | 0.3° |
These numbers mean the coupling can handle small shifts. It does not lose performance. The rubber bends and stretches to keep shafts joined. Y&F CF-A couplings use similar designs. They help manage misalignment. This stops extra stress on machine parts. It helps everything last longer.
Note: Maintenance-free features save time and lower costs for operators.
CENTAFLEX-A Sizes
Range
CENTAFLEX-A couplings come in many sizes. They fit lots of machines. The smallest size is 2. The biggest size is 800. This means they work for tiny and huge equipment. Each size matches a certain torque and shaft width. For example, size 25 fits a 25 mm shaft. Bigger sizes can fit up to 800 mm shafts. Engineers pick the right size for each machine. They look at how much power and what shaft size is needed.
Y&F CF-A Series also has many sizes. Customers can pick standard sizes or ask for special ones. This helps people find the best fit for pumps, fans, and more.
Tip: Picking the right size keeps machines safe and helps them last longer.
Dimensions
CENTAFLEX-A couplings are made with exact measurements. Each model has its own inner and outer diameter and length. These numbers help users match couplings to their machines. No extra changes are needed. Here are some common sizes:
Size Number | Inner Diameter (mm) | Outer Diameter (mm) | Length (mm) |
|---|---|---|---|
25 | 25 | 80 | 60 |
140 | 140 | 320 | 120 |
800 | 800 | 1600 | 300 |
You can use adapters, flanges, or hubs to mount them. These choices make putting them in easy and strong. System codes help you pick the right type. CENTAFLEX-A uses codes like Type 0, Type 1, Type 2, Type 3, and Type G. Model codes look like CF-A-140 or CF-AS-140. Hole types are marked as CF-A-OS for straight holes and CF-A-O0 for step holes.

Installation
Good installation makes couplings work well and last long. Technicians need to follow simple steps when putting couplings on shafts. First, they check if the shafts line up right. Good alignment stops stress and early wear. Next, they look at all coupling parts for damage or dirt. Clean parts work better and last longer. Using good lubricant lowers friction and helps things move smoothly. Regular checks help find problems early. Maintenance teams look for wear or misalignment. They clean the coupling and check for loose bolts or parts.
Installation Step | Purpose |
|---|---|
Check shaft alignment | Prevents stress and wear |
Inspect components | Ensures reliability |
Clean parts | Minimizes wear |
Lubricate as needed | Reduces friction |
Perform regular checks | Detects issues early |
Note: Doing regular maintenance and careful installation helps couplings last longer and keeps machines running.
Picking the right coupling needs you to think about a few things. Engineers look at the hole type and size marks. They also check what materials are used. This helps make sure the coupling fits and lasts long. They look at how much torque it can handle. They check if it works in hot or cold places. They see if it can deal with shafts that do not line up. These things help the coupling work well. Couplings like Y&F CF-A help by soaking up shocks. They lower stress and are easy to put in. Looking at datasheets or asking experts is smart. This helps you match flange sizes and hub fit. Doing this makes sure machines work well for a long time.
