In addition to seals or guards, there are other suffixes such as cage design, materials, heat treatment, accuracy, clearance, preload, quiet operation, stability, lubrication, and other special specifications.

The third and fourth digits in the bearing model number are important because they usually represent the bearing’s inner diameter (ID) in millimeters. They provide important information about the fit of the bearing to the shaft on which it is mounted.The bore diameter in the bearing model number ranges from 0 to 3, representing 10 to 17 mm.For numbers above “03”, the bore size is calculated as 5 times the value represented by the 3rd and 4th digits in the bearing model number.For example, in “6206”, “0 6” corresponds to the bore diameter, therefore, “0 6” translates into a bearing bore diameter of 6*5=30mm.If there is no fourth digit in the bearing model number, the third digit represents the bore diameter.For example, for a bearing size “234”, the number “4” (equivalent to 4 mm) indicates the bore diameter.

On average, the cost for a Ford Escape Wheel Bearings Replacement is $210 with $70 for parts and $140 for labor. Prices may vary depending on your location.

The bearing model number is a guide in identifying the bearing type, typical uses, durability and suitability. No matter what brand of bearing you buy, as long as you understand the meaning of the standard bearing model number, you can accurately identify the bearing you need. It’s worth noting that bearing model numbers are not universally standardized and may vary from brand to brand. As the top bearing manufacturer and supplier in China, we believe it is necessary to train non-technical personnel with bearing needs. Today we will discuss bearing numbers to identify bearings.

Tire and wheel assembly does not turn smoothly. With the wheel jacked up, and the car not in gear, the wheel should rotate smoothly. Rough or inconsistent movement, which is often accompanied by noise, can signify damaged bearings. Be sure the brakes are not dragging as you perform this check.

Bearingcodes and sizes

Identifying bearings by number requires understanding the bearing terminology and numbering system used by the manufacturer. Each bearing model number encodes specific information about the bearing type, size and design. Typically, this number includes a series code indicating the bearing type, a size series code indicating the bearing’s dimensional characteristics, and additional suffixes indicating specific design features such as seals, guards, or internal clearance. It is important to know whether the manufacturer follows the ABMA bearing code standards or uses a different standard. All manufacturers provide code keys on their websites or catalogs to help users interpret or specify the bearings required for their application. Regardless of which numbering system is used, each number and letter used in a bearing code has a specific meaning and helps identify the type and specification of the bearing. Many manufacturers or distributors offer bearing model number crossovers to facilitate interchange of bearings from one manufacturer to another. Due to the lack of interchange guidance for other bearing manufacturers, most suppliers will provide information for switching between their numbers and the ABMA standard.

The complexity of wheel bearing replacement varies greatly depending on the vehicle make, model, year, the wheel position (front versus rear), and the drive type (AWD versus FWD):

* In case there is no fourth digit, then the 3rd digit indicates the bore size in mm. For example: in case of bearing 636, the bore size of the bearing will be 6mm

The second digit in the bearing model number usually indicates the bearing series. It reflects the sturdiness of the bearing, and its number indicates the light, medium or heavy series. Therefore, this number can give you insight into the bearing’s ability to handle different loads. For example, in “6 2 0 6”, the second number “2” means “very thin part”.

Axial or radial play in the wheel or wheel hub. Should the wheel hub move up and down or in and out, the bearing may be worn.

Vibration in the steering wheel or vehicle body and/or wandering. Vibration and lack of directional stability could be consequences of loose or worn out wheel bearings.

The starting number in the bearing model number is significant because it usually indicates the type of bearing. It helps determine the core design of the bearing. For example, in “6206”, the first number “6” means “single row deep groove ball bearing”. The table below lists the various types of bearings and their type codes.

Growling or grinding noise from a wheel. Failed or failing wheel bearings make a very characteristic growling noise which will grow louder as the bearing wear progresses. If you believe the wheel bearing noise is coming from one side of the car, you can self-diagnosis your wheel bearing as you drive the car by loading and unloading vehicle weight You can do this by “swerving” from side-to-side. For example, if the noise markedly increases when you swerve to left, which shifts the vehicle’s weight to the right, then it often indicates the wheel bearing on the right is failing.

Suffixes indicate different designs or variations that deviate from the original or current basic design. For example, shielded bearings and sealed bearings have different suffixes. For “6 2 0 6 LLB”, “LLB” stands for bearings with non-contact rubber seals.

The prefix mainly indicates a specific component of the bearing, but may also identify various bearing variants. Let’s take the NTN prefix as an example. In terms of thermal stability:

A wheel bearing assembly consists of rolling elements, such as hardened steel ball bearings or roller bearings, that roll on and around hardened steel bearing races. The wheel bearings support the front and rear axle, and all the weight of your car. Wheel bearings are made with a high-precision technique using extremely hard steel in order to withstand all the normal impacts that occur to the wheel and tire assembly as you drive along the road.

The series of numbers and words in a bearing model number may seem confusing, consisting of several paragraphs, each providing specific information about the bearing. Typically, a bearing model number consists of three distinct parts: prefix, base name, and suffix. The bearing model number indicates the specifications of the bearing, including bearing type, overall dimensions, running accuracy and internal clearance. This is true for the ABMA bearing codes as well as the codes used by Aubearing, which is similar to the numbering system used by many other manufacturers. Take NTN deep groove ball bearing code “TS2-6206 x1 LLB N C3 P5/2AS” as an example:

No. Wheel bearing failure is usually gradual, although in some cases it starts immediately after the dramatic impact of the wheel and tire assembly with a deep pothole. Wheel bearings can sometimes make noise for quite some time before you experience a catastrophic failure that would result in complete separation of the wheel and tire assembly from the axle. Generally, the risk of sudden failure increases with the noise level. But strictly speaking, once the bearing has started to fail it is impossible to predict exactly when it will fail completely. So it should not continue to be driven. Were a failing bearing to seize or break while you are moving, you could experience loss of control of the vehicle. Once you receive a conclusive diagnostic that a wheel bearing has failed, replace the bearing promptly.
