Coupling a pump shaft (spline shaft) to a cylindrical hub

Spline Coupling Manufacturer – Maintain High Torque and Grip 

Deal with challenging components inside the excavators through spline couplings. They are in the best form at Guangzhou Xiebang Machinery Co., Ltd. We manufacture them with precise diameter, thickness, and teeth strength. You can expect an unbelievable performance from them. They will maintain high torque with the shafts. Another feature is the grip they form through their teeth. Both these advantages will create a secure installation of couplings.

Compact Designs for Higher Compatibility with Gears

Their compact designs will meet the compatibility level of your excavators. The axles and shafts will shift the force better through spline couplings. This creates a need for a manufacturer of spline couplings. Guangzhou Xiebang Machinery is one of the best names in the industry. The performance of the excavators will improve significantly. All because of the designs and durability of couplings.

Reducing Misalignments, Secure Grip on Shafts

Another primary advantage is that they will offer their adjustment with misalignments. Their teeth will create a firm grip on the shafts. For that reason, you can find a trustworthy spline coupling supplier. That supplier is available here with proven coupling performance. We maintain a level of grip between the teeth and the shafts. There is complete coordination between them after you install them.

We Go Beyond the Borders with Mega Supply

 

Guangzhou Xiebang Machinery offers international supply of spline couplings. Buyers in the excavators market can get bulk supply from us. We maintain the quality of couplings at a high level through strict inspection. Everyone has an opportunity to place bulk orders for international supply. Our supply will reach you wherever you are.

YNF Machinery is committed to providing total solutions for excavator accessories. The coupling is one of the most important accessories. In the center of the coupling – the spline hub, although the damage rate in daily use is very low, a high-quality spline can greatly reduce the damage to the hydraulic pump and engine during the operation of the machine.

■ Materials

If the material is not strong enough on the flywheel side, it can be compensated for by changing the bolt length. YNF Machinery is always using the best material to provide the cylindrical hub.

How many different hubs do you have?

There are two ways to categorize the spline hubs, one is by the outer diameter, and the other is by the inner teeth.

YNF Machinery provides spline hubs with 60mm outer diameter to 160 mm outer diameter. Also, we provide the hubs from 0 teeth hubs (key-way hub) to 27 teeth hubs.

Moreover, we also have the ability to produce the hubs according to your requirement. We provide customized service for our customers.

How can I confirm which spline hub I need?

There are 4 steps to confirm the spline hub that you need:

  1. Measure the outer diameter. To categorize a hub by the outer diameter is a good way. So it’s easy to confirm it by its outer diameter. There are 60 mm outer diameter, 70 mm outer diameter, 85 mm outer diameter, 100 mm OD, 125 mm OD, and 160 mm OD.
  2. The second step is to count the inner teeth. Because the inner teeth of the spline hub are connected to the pump shaft, you can also count the teeth of the pump shaft. So far, we have developed the following teeth types: 0 teeth, 9 teeth, 10 teeth, 11 teeth, 12 teeth, 13 teeth, 14 teeth, 15 teeth, 16 teeth, 17 teeth, 21 teeth, 22 teeth, 24 teeth, 27 teeth.
  3. The third step is to measure the inner diameter. Our spline hubs meet different standards which areJIS D2001, SAE J498b and ANSI B92.1. So it’s easy to find the hubs that you need for your machine. If you don’t know what standard of the hub you need, you can just send us the measurement of the hub. We’ll confirm it for you.
  4. The last step is to check the height of the hub. If you have the old hub at hand, just measure your old hub. Or you can check your pump. The hub is usually slightly shorter than the pump shaft making sure there’s enough room.
I want you to customize the spline hub for me. What information I should send you?

There are two kinds of customization ways.

In one situation, you have the old hubs in your hand. In this situation, you can send us the photos and dimensions of the hub to our staff. We’ll confirm the correct hub for you. If we don’t have the hub in stock, we’ll confirm if we have the teeth mold, and we can make it based on our mold. Or you’ll have to send the sample to us.

The second situation is that you only have the drawing. In this case, you can send us the drawing of the hub to our staff and our staff will confirm the details with you.

Can I order the spline hub which are made of other material?

No, sorry.

Currently, the material of the spline hubs we produce is S45S which is the most suitable material. Because we are producing it in bulk, with scale production, we can order the material at a lower cost. If producing with other materials, the cost will be much higher causing the product price high.

What couplings do these spline hubs fit for?

The spline hubs fit the Centaflex-A couplings and Centaflex-H couplings.
