Q: How do my car’s hub bearings affect braking safety?

A: Your car’s hub bearings include the wheel speedsensor that controls your anti-lock braking system (ABS). This sensor sends a constant signal to theABS control system, telling it how fast each wheel isturning. In an emergencysituation, the ABS controlsystem will determine if anti-lock braking is required. If the ABS sensor doesn’t work properly or fails,
the ABS system fails, so the quality of this sensor (how it is made and protected from damage) is critical to braking safety.

Q: Why are hub bearings critical to my traction control system?

A: Your car’s traction control system (TCS) uses a combination of electronic drivetrain controls in conjunction with the ABS system. Since it uses the same wheel speed sensors and components as the ABS system, it can be considered a subsystem and extension of that system. Together, ABS and TCS work to provide the driver with full control over the vehicle under potentially dangerous road conditions.

Q: Who is Kelunte and what makes their hub bearings better – and safer?

A: Kelunte manufactures Original Equipment hub bearings for many automakers all over the world. Our premium quality hub bearings are manufactured using high quality steel and surface finishes, premium seals, OE sensors, precision manufacturing techniques and precise assembly tolerances. Every Kelutne premium hub is 100% tested, that means it will fit correctly and work correctly, and last as long as the original hub that came with the car when it was new.
In many cases, it’s the same one!

Q: What is a wheel hub bearing and why is it so important?

A: Though you may never even see it, a wheel hub bearing unit is an important part of your car’s wheel assembly, enabling your wheels to turn freely and playing a crucial role in the safety and handling characteristics of your vehicle. Comprised of precisionmanufactured bearings, seals and sensors in one preassembled unit, a wheel hub bearing unit is critical to your car’s performance, from the smoothness of the ride, to fuel efficiency, to the integrity of your anti-lock breaking system (ABS). So when it’s time to replace one, you’ll want a replacement hub bearing that’s as good – and safe – as the original that came with your car when it was new.

Q: Why are “value grade” hubs a risky choice?
A: Many manufacturers sell replacement hub bearings that are very low priced. Initially, you may think that is
a great deal or value. Unfortunately, with that low price, you get a low quality hub bearing that is inferior to a
premium, Original Equipment quality hub bearing. We call these hubs “value grade,” and experience has
proven that these low performing “value grade” hubs are no real value in the long run. In fact, in many cases:
• Value grade hubs last less than half as long as premium hubs.
• Their cheaply made seals can allow moisture and contaminants to enter and destroy the bearing prematurely     – requiring you to pay for a new hub in as little as 10,000 miles.
• They can produce annoying wheel vibration and noise.
• They can cause your anti-lock braking system to malfunction, leading to safety concerns for your
   vehicle.
• They can even result in your wheel coming off while you are driving – potentially causing a fatal accident.

The main functions of wheel hub bearings are load and provide accurate guidance to the turn of hub bearings. Hub bearings not only carry axial load but also carry radial load, they are important components. They can carry heavy radial load which include axial and radial load and torques load, they can limit axial displacement both sides. They are mainly used in components which limitation of bearings and shell axial displacement of both sides. Hub bearings' design are familiar to the two back to back order single row conntact ball bearings, but the width are shorter than single row bearings. Compare to the single row bearings hub bearings have better rigidity.
