Wheel bearing consists of a set of steel balls held together by a metallic ring (race). They are fitted inside a hollow chunk of metal called hub. For wheel bearings to be correctly installed into hubs, a wheel bearing press is required.A wheel bearing press applies the principle of pressure to either fit or remove a wheel bearing. The common types of wheel bearing include the hydraulic press and the mechanical press the former uses fluid pressure in fastening or loosening wheel bearings while the latter uses mechanical pressure.

A wheel bearing press provides full power stroke that helps fit bearings to their capacity in a safe and secure manner to avoid damage or overloads. Poorly fitted wheel bearings can cause the balls to collapse which may have fatal consequences.

Factors to choose a wheel bearing press

When buying a wheel bearing press, one should consider the tonnage. Tonnage refers to the pressure exertion capacity of press. Modern wheel bearing presses also offer a broad range of accessories depending on the user's requirements and financial capabilities. Such accessories include:

  • Pressure reversal hydraulic switches
  • Automatic (continuous) cycling
  • Sliding bolsters and rotary index tables
  • Ejection cylinders or knockouts
  • Touch screen controls
  • Distance reversal limit switches
  • Servo system feedback for precise, consistent and repeatable stroke control.

The quality of press also matters depending on the type of job at hand. Quality aspects that differ from press to press include:

  1. Cylinder diameter.
  2. Maximum system pressure i.e. point at which press develop full tonnage
  3. Frame; Frame construction-rigidity, dimensional capacity.
  4. Horsepower, about the duration, length, and speed of the pressing stroke.

Choose a gear

Since gears are a torque multiplier that changes the ratio of the rear end, the higher up the number, the shorter each gear is. Hence gets one up to their power band quicker. 4:10 gears, therefore, mean that the driveshaft will turn 4.1 times for each single wheel turn. Using the final output ratio of the transmission, it is multiplied times 4.10 to get the effective rate of engine revolutions to tire revs. 4.10 gears make drag times faster and deliver more power to the wheels faster hence boosting the performance of a vehicle. Most mechanics may, however, argue that this gear ratio change makes little or no difference on highways.

Factors to consider when choosing 4:10 gears include:

  1. Tire size
  2. Fuel consumption: in case one's car is a fuel guzzler; it is not wise to have such high gear ratios.
  3. Type of vehicle; different vehicles serve various functions.

Some vehicles are for cargo and load carriage, others for luxury purposes and others for sports such as race cars. 4:10 gears can, therefore, work best in high performance requiring vehicles as opposed to luxury cars.Just as all forms of wheel bearing press are important depending on their functions, also gear ratios are necessary depending on the use of vehicles. For instance, vehicles requiring high performance such as racing cars may necessitate a higher gear ratio than regular cars. One should, therefore, put such factors into consideration before purchasing making any installations or changes in their cars to avoid incompatibility or any other mechanical complications that may arise.
