Bearing Description

Introduction to angular contact ball bearing

1) Angular contact ball bearing is especially suitable to be subjected to the combination of radial and axial load compared with other types of ball bearings. The bigger the contact angle is, the higher axial load withstanding ability it has.

2) The high precision and high speed angular contact ball bearings usually adopts 15°angle.

3)The angular contact ball bearing could be divided into 2 types according to the quantity of roller rows, that are single row and double rows angular contact ball bearings.

4) Conventionally, there are 3 assembly ways for the angular contact bearings, back to back type(i.e 7000/DB) ,face to face type(i.e 70000DF) and series assembly type(i.e 70000/DT).

5) Applications such as lathe main axle, high frequency motor, food machinery,oil pump, fan and blower, and others are recommended to use the angular contact ball bearings, either single row or double rows type.

Reasons to Choose Us ?

Reasons to choose CZPT Bearings as your Chinese Good Performance Angular Contact Ball Bearing partner

1. Bearing designing: Guomai has our own bearing R&D team and adopts Germany technology. This enables us to provide OEM and ODM service to you.
2. Production process: We strictly follow the 5S production process and acquired ISO9001:2008 quality management system certificate. Besides, we introduced from abroad world famous brands lathes and heat treatment equipment, this enables us to provide high precision bearings with similar quality to world famous brands such as SK F,TIMKEN,NSK,NTN,KOYO,NACHI and so on.
3. Materials: To ensure the high quality of bearings, we use high carbon chrome bearing steel which provides high rigidity, and high resistance to CZPT wear to produce the bearings. Low carbon cold rolled steel and low carbon stainless steel is also used according to customers’ requirements.
4. Quality inspection: All bearings will be strictly tested before packing. We have CZPT talysurf, hardness meter,clearance detector,vibration(speed) measuring instrument,roundness instrument to guarantee all bearings are qualified with the standards.
5. Lubricants: Suitable lubricants are used to protect the bearings from oxidation or corrosion of parts thus enable our bearings with longer lifetime, low noise and better high temperature performance. Selection of lubricants is generally governed by the bearing application. Right choice of high quality lubricants could prevent metal to metal contact and conduct heat away from the bearings.
6. Packing: Guomai bearings pay attention to every detail in the bearing production process. We adopt plastic bag, Kraft paper, thick paper box and cartons to protect the bearings from unexpectable damage during the transportation and warehouse stock.
7. Factory direct marketing: We are the factory and not the distributor or trading agent, so we could provide the same quality with competitive price.

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.

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.
