ZheJiang Qilu Industrial Co., Ltd were already engaged in exporting steel for 11 years, could supply a great variety of hot forged, hot rolled and cold drawn Steels,  including engineering steel, cold work tool steel, hot work tool steel, plastic mold steel, spring steel, high speed steel, stainless steel etc., besides Qilu Industrial also has their own heating treatment shop and machining shop to provide heating treatment, cutting and further machining service.

Since 2008 year, ZheJiang Qilu Industrial has the right to export all FORGED STEEL behalf of Qilu Speical Steel Co.,ltd which is specialized in smelting and forging of special steel since 1965 year, now Qilu special steel is 1 of the biggest manufacturer of forged product in China.The forged products are used in Automotive, Aerospace, Power Generation, Oil & Gas, Transportation and Industrial. 

Till 2013 year, many customers need HOT ROLLED and COLD DRAWN steel from Qilu Industrial, in order to provide one-stop solution to our customers, Qilu Industrial began to cooperate with Xihu (West Lake) Dis.bei Special Steel (HangZhou and HangZhou mill), Baosteel, Tiangong International, Changcheng Special Steel for hot rolled tool steel, cooperate with HangZhou Speical Steel, HangZhou HangZhou Speical Steel, Shagang Group, CZPT Group for hot rolled engineering steel. Now we already set up the warehouse in HangZhou and HangZhou City, more than 20000 tons ex-stock could be supplied with kinds of sizes.

Then from 2018 year, Qilu Industrial decide to provide further manufacturer processing service, at present we could supply various of lage main shaft, turbin shaft, cylinder shaft, windy generator shaft, roller shaft, wheel forging, drill bit forging and kinds of irregular parts based on the drawing provided by customers.

Qilu Industrial is the professional one-stop steel manufacturer, stockist and exporter in China, our customers spread all over the world, include West Europe, North America, South America, Asia, Middle Asia, Africa, Australia, etc.

Standard Length Splined Shafts

Standard Length Splined Shafts are made from Mild Steel and are perfect for most repair jobs, custom machinery building, and many other applications. All stock splined shafts are 2-3/4 inches in length, and full splines are available in any length, with additional materials and working lengths available upon request and quotation. CZPT Manufacturing Company is proud to offer these standard length shafts.

Disc brake mounting interfaces that are splined

There are 2 common disc brake mounting interfaces, splined and center lock. Disc brakes with splined interfaces are more common. They are usually easier to install. The center lock system requires a tool to remove the locking ring on the disc hub. Six-bolt rotors are easier to install and require only 6 bolts. The center lock system is commonly used with performance road bikes.
Post mount disc brakes require a post mount adapter, while flat mount disc brakes do not. Post mount adapters are more common and are used for carbon mountain bikes, while flat mount interfaces are becoming the norm on road and gravel bikes. All disc brake adapters are adjustable for rotor size, though. Road bikes usually use 160mm rotors while mountain bikes use rotors that are 180mm or 200mm.
splineshaft

Disc brake mounting interfaces that are helical splined

A helical splined disc brake mounting interface is designed with a splined connection between the hub and brake disc. This splined connection allows for a relatively large amount of radial and rotational displacement between the disc and hub. A loosely splined interface can cause a rattling noise due to the movement of the disc in relation to the hub.
The splines on the brake disc and hub are connected via an air gap. The air gap helps reduce heat conduction from the brake disc to the hub. The present invention addresses problems of noise, heat, and retraction of brake discs at the release of the brake. It also addresses issues with skewing and dragging. If you’re unsure whether this type of mounting interface is right for you, consult your mechanic.
Disc brake mounting interfaces that are helix-splined may be used in conjunction with other components of a wheel. They are particularly useful in disc brake mounting interfaces for hub-to-hub assemblies. The spacer elements, which are preferably located circumferentially, provide substantially the same function no matter how the brake disc rotates. Preferably, 3 spacer elements are located around the brake disc. Each of these spacer elements has equal clearance between the splines of the brake disc and the hub.
Spacer elements 6 include a helical spring portion 6.1 and extensions in tangential directions that terminate in hooks 6.4. These hooks abut against the brake disc 1 in both directions. The helical spring portion 5.1 and 6.1 have stiffness enough to absorb radial impacts. The spacer elements are arranged around the circumference of the intermeshing zone.
A helical splined disc mount includes a stabilizing element formed as a helical spring. The helical spring extends to the disc’s splines and teeth. The ends of the extension extend in opposite directions, while brackets at each end engage with the disc’s splines and teeth. This stabilizing element is positioned axially over the disc’s width.
Helical splined disc brake mounting interfaces are popular in bicycles and road bicycles. They’re a reliable, durable way to mount your brakes. Splines are widely used in aerospace, and have a higher fatigue life and reliability. The interfaces between the splined disc brake and BB spindle are made from aluminum and acetate.
As the splined hub mounts the disc in a helical fashion, the spring wire and disc 2 will be positioned in close contact. As the spring wire contacts the disc, it creates friction forces that are evenly distributed throughout the disc. This allows for a wide range of axial motion. Disc brake mounting interfaces that are helical splined have higher strength and stiffness than their counterparts.
Disc brake mounting interfaces that are helically splined can have a wide range of splined surfaces. The splined surfaces are the most common type of disc brake mounting interfaces. They are typically made of stainless steel or aluminum and can be used for a variety of applications. However, a splined disc mount will not support a disc with an oversized brake caliper.
