Detail description for barbell bar (customize your personalized barbell) :

•   Sleeve  

          Sleeves are used to load weight plates; the longer the sleeve, the more plates can be loaded.

          The surface of the sleeves can be smooth during the turning process, and it can also retain the turning marks. 

          If the surface of the sleeves is smooth, the friction will be reduced when the sleeve is locked with collar, which has the advantage of protecting the plating on the surface of the sleeve from being damaged;

          If the surface of the sleeve retains the Turning tool pattern, the friction will be increased when locking with collar, but when loading and unloading plates, 

          it will make a crisp sliding sound, even though this way is easy to cause damage to the plating layer on the surface of the sleeve, there are still a lot of customers prefer this way.

          Either way, according to our decades of production process and customer feedback, there has not been any problem, please be assured and leave a message to tell us which one you prefer. 

•   Flange (shoulder)  

          Flanges can be used to block the movement of the weight plates, or the overall weight of the barbell can be adjusted by modifying the dimensions;

          Sometimes, in order to load more weight plates, The width of the flange will be increased to ≤20mm.

          As the width of the flange gets wider, the force of the load on both sides goes outward, which makes a difference.

•   Bearing  

          Eako has 2 kinds of bearing for barbell, Needle bearing and ball bearing.

          Ball bearings: Reduce the contact surface between balls, helping to reduce noise and improve system stability. Due to the small size of ball bearings, they have an average load capacity, so they are generally used in less expensive barbells；

          Needle bearing: The rolling elements of needle bearings are needle-shaped, which allows them to bear a greater loads. They are suitable for high load-bearing barbells and are much more expensive than ball bearings.

We can customize according to customer's demand quantity, such as installing 1, 2, 3, 4, or 5 sleeves on each side of the sleeve.

•   Bushing  

Outside bushing of sleeve

Eako has 2 kinds of outside bushing of sleeve, copper bushing and stainless steel bushing.

Generally, stainless steel barbells are matched with stainless steel bushings, other materials barbells are matched with copper bushings. Barbell bushings can also be selected according to customer requirements.

Inside bushing of sleeve

Eako has 2 kinds of inside bushing of sleeve, copper bushing and graphite copper bushing.

These two kinds of inside bushing are used to replace the bearings inside the sleeve and do not require high rotation like the bearings.

Graphite is added to the graphite copper bushing, which can provide lubrication during rotation. Compared with copper bushings, the cost is more expensive.

•   Knurling  

1. Hill knurling: Flat design can undoubtedly avoid tearing the palm, scratching the calf, at the same time the palm touch is relatively mild,suitable for small light training.

2.Mountain knurling: These small, sharp bumps allow the trainer to grip the barbell into the skin of the palm, making the barbell more integrated into the palm and less prone to slipping or displacing.when the high grip strength is required, these sharp bumps will easily hurt the skin of the hand of the trainer with the rolling of the barbell bar.

3.Volcano knurling:The palm skin is squeezed into the pit at the top of the raised diamond by the force of the gripping, which makes the skin more tightly connected to the barbell, increasing friction.

•   Surface treatment  

The purpose of barbell surface treatment is to increase wear resistance and corrosion resistance.

Usually, barbell surfaces will use two types of surface treatments, one is electroplating and the other is coating. 

Coating:

Ceramic paint for shaft (handle bar), colors can be customized, colourful as shown:

Electroplating:

•   Material  

The materials used by Eako on barbell shaft (handle bar) are generally carbon steel, alloy steel and stainless steel.

In addition, In 2020 year, we have collaborated with the China lron and Steel Research Institute tocustomize specifically for barbell bar products, Developed two materials: customized alloy steel and customized stainless steel. We have adjusted and optimized the elements and composition ratio of these two materials, The mechanical properties are better than those of the other materials.

At present, we can achieve the PSI of materials for barbell：190,000 PSI to 248,000 PSI. Customers can determine the material of the shaft to be used based on their own needs.

•   Packing  

We have two types of packing for barbell: carton and paper tube.
