This suffix indicates that the bearing is designed for very high operating temperatures. In general, the temperature is indicated after this suffix.Beware, these bearings are not suitable for all applications, and will require a high temperature for optimum service life.

Pack the new smaller bearing with grease and slide it on to the spindle inside the rotor. Now install the thrust washer and retaining nut onto the spindle.

Step 3: Lift up the vehicle. Use the floor jack and a pair of safety jack stands to lift and secure the vehicle. This will allow you to safely remove the tire.

Some bearings are available with more or less important variants (high or low internal clearance, special grease, very high temperature, etc.). These variants are systematically indicated by prefixes and suffixes in the part number.For example, the suffix "2RS" means that the bearing is splash-proof, thanks to a sealing flange on both sides of the bearing.The suffix "C3" means that the bearing has increased internal clearance, and will require a higher operating temperature, or a higher rotation speed.

These suffixes indicate that the cage (the part of the bearing that holds the balls apart) is made of polymer material. Usually made of glass-fiber-reinforced polyamide.

Step 4: Remove the lug nuts. With the vehicle lifted and secured, remove the lug nuts completely and then remove the tire and place aside.

Congratulations, you have successfully changed your vehicle’s wheel bearing. It is important to perform a test drive after changing the wheel bearings to ensure that the repair is complete.. If you encountered any problems while changing your wheel bearings, call a professional mechanic, such as one from YourMechanic, to replace them for you.

Changing your own wheel bearings is considered an intermediate job that can be done at home, but will need some speciality mechanic tools. The steps provided below are generalized to cover the three most common types of wheel bearings that are found on most vehicles. Be sure to obtain your vehicle's service manual and identify the type of wheel bearing your vehicle is equipped with before you begin the repair.

Step 2: Install the tire. Replace the wheel and tighten the lug nuts by hand. Support the vehicle with a floor jack and remove the safety jack stands. Slowly lower the vehicle until its tires just touch the ground.

These suffixes mean "with 1 or 2 sheet metal deflectors", for dust-tightness. At 123Roulement, we specify whether the bearing is sealed on 2 sides with "ZZ".

Step 3: Complete the installation. Use a torque wrench to tighten the lugnuts to manufacturer specifications. Lower the vehicle completely and remove the floor jack.

Step 7: Unbolt and replace the hub. Some cars have permanently sealed front wheel bearings as shown in the image above. The rotor mounts on a hub that contains the pressed-in wheel bearing.

Step 8: Remove the spindle if needed. If your bearing is pressed into the spindle, it is recommended that you remove the spindle from the vehicle and take both the spindle and the new wheel bearing to your local repair shop. They will have the specialty tools to press out the old bearing and press in the new one.

The Deep Groove Ball Bearing, known as 95DSF01-A1-CG37-NSK NSK, has an inner diameter of 95 mm, an outer diameter of 120 mm and a thickness of 17 mm.

These suffixes mean "with 1 or 2 rubber seals". At 123Roulement, we use the number "2" to specify when the bearing is sealed on both sides.

Step 6: Install a new cotter pin. Tighten the retaining nut until it is snug and turn the rotor counterclockwise at the same time.

Step 4: Rub bearing grease into the casing. Place the rotor face down on the floor with the back side facing upwards. Take the new larger bearing and rub the bearing grease into the casing.

A stainless steel bearing is generally magnetizable, as it is made from AISI 420 stainless steel, which is harder and more shock-resistant than standard stainless steel (AISI 304).To check whether your bearing is made of stainless steel, simply read the reference engraved on the side of the bearing. This reference should begin with the prefix "S" meaning "Stainless Steel".

Step 1: Remove the brake caliper and bracket. Use your ratchet and ⅜ socket set to unbolt the disc brake caliper and bracket from the spindle. Use a screwdriver to remove the caliper itself.

To do this, use your pliers to remove the cotter pin and retaining nut and then slide the rotor forward to release the outer wheel bearing(smaller wheel bearing).

Means "increased internal clearance". Often referred to as high-speed, this means that the bearing is designed for high rotational speeds and moderately high temperatures. CAUTION: a bearing with increased internal clearance will not operate optimally at low speeds. Please refer to the data sheet for the bearing you are looking for to find out its rotation speed limit.

Wheel bearings are parts that allow the wheels on your vehicle to spin freely and with as little friction as possible. A wheel bearing is a set of steel balls that are housed in a metal case known as a race, and it is located inside the wheel's hub. If you hear a moaning or humming sound while you are driving, it is likely that one of your vehicle’s wheel bearings is starting to fail.

Step 1: Put the brake rotor and caliper back on. Now that the new bearing is installed, the brake rotor and caliper can be placed back onto the vehicle using a ratchet and the appropriate sockets that were used to remove them.

The ABEC standard is used to classify bearings according to their machining tolerance. This standard is regularly called into question because it does not include certain technologies that are important for guaranteeing proper operation, both in terms of efficiency and bearing life.123Roulement therefore makes little use of this standard.

Step 3: Remove the rotor and inner wheel bearing. Replace the retaining nut on the spindle and grab the rotor with both hands. Proceed to pull the rotor off the spindle, allowing the larger inner bearing to get caught on the retaining nut, and release the bearing and grease seal from the rotor.

Step 5: Install the new bearing. Place the new bearing into the back of the rotor and apply grease to the inside bearing cavity. Install a new bearing seal over the new larger bearing and slide the rotor back on to the spindle.

In most cases this service can be done inexpensively. Once the new bearing pressed in, the spindle can be installed back on to the vehicle.

Step 2: Remove the outer wheel bearing. If the wheel bearings are housed inside your disc brake rotor, as often seen in trucks, you will need to pry off the central dust cap to expose the cotter pin and retaining nut.
