How to choose Hub Unit Bearings

Points to check when selecting, with the values for this product (ONI Product Compatibility Table (RIM)).

1. 1. Select a capacity that matches the axle load of the vehicle

   Hub unit bearings directly bear the vehicle weight and the loads during driving, so confirm that the axle load of the target vehicle falls within the applicable range. The listed products cover a range of 4.9 to 19.7 kN, and the required capacity differs greatly between kei cars and SUVs. For applications where the axle load increases due to loading or towing, select with a margin.

2. 2. Match the wheel mounting dimensions

   The wheel cannot be installed unless the pitch circle diameter (P.C.D.) of the wheel bolt holes and the number of bolts match those of the wheel side. The listed products have a P.C.D. of 100 to 139.7 mm and 4 to 6 bolts. Check the P.C.D. and bolt count as a combination, and verify together with the brake disc mounting.

3. 3. Confirm the generation (structure) and mounting method

   The vehicle body side mounting structure differs by generation: the first generation press-fits the bearing unit alone into the housing, while the second and third generations fasten the flange with bolts. For repairs of existing vehicles, the same generation and shape must be selected; for new designs, compare assembly man-hours, weight, and rigidity to determine the generation.

4. 4. Distinguish between drive wheel and driven wheel use

   The shape of the inner ring differs: drive wheel types have a spline hole for passing the drive shaft, while driven wheel types do not. The classification of each wheel changes with front-wheel drive, rear-wheel drive, and four-wheel drive vehicles, so confirm whether the mounting position is a drive wheel or a driven wheel before selecting the part number.

5. 5. Check ABS sensor compatibility

   For vehicles equipped with ABS or vehicle stability control, a hub unit with a built-in encoder (magnetic ring) or sensor for detecting wheel speed may be required. Confirm that the sensor type and mounting position match those of the vehicle, including the presence or absence of the encoder.

6. 6. Compare low torque and sealing performance

   The rotational resistance of the bearing affects fuel economy and electric power consumption, and some listed products claim a 50% torque reduction compared with current products. On the other hand, reducing seal contact increases the risk of muddy water intrusion, so also check for measures against muddy water such as labyrinth structures, and whether the product suits the usage region and road conditions.
