The FAG brand started with an ingenious idea. In 1883, Friedrich Fischer designed a ball grinding machine in Schweinfurt, Germany that, for the first time, made it possible to produce absolutely round steel balls by grinding. This invention is regarded as the foundation for the entire rolling bearing industry. This is one of the reasons why FAG has long been considered to be a pioneer in rolling bearing technology. Today, FAG is one of the leading brands for applications in machine building, the automotive industry and in aviation and aerospace technology. The Schaeffler Group's FAG brand has companies, subsidiaries and sales agencies in all major industrial countries.

Since 2001, FAG has been part of the Schaeffler Group and has been active in all of the group’s divisions – Aerospace, Automotive and Industrial. Together with INA’s complementary product range, FAG has one of the widest product portfolios in the rolling bearing industry, covering nearly all applications in production machinery, power transmission and rail technology, heavy industry and consumer products.

    Engine bearings are used in between two parts of an engine where a good deal of motion will occur. These bearings serve the two main functions of reducing friction between the rotating parts of an engine and supporting the crankshaft. Friction is reduced by having two lubricated different metals slide against each other. When a bearing fails due to dirt or debris, a lack of lubrication,or human error, it can cause your engine major harm. There are three main types of engine bearings that keep your engine running smoothly
  • Connecting Rod Bearings

    • Connecting rod bearings are metal inserts that protect the wear and tear in between the connecting rods and the crankshaft. These rods are the link between the pistons and the crankshaft. When the crankshaft rotates, it is the connecting rods that move the pistons down and up in their cylinder bores. This constant motion may cause the bearings to wear out over time, which will impact fuel efficiency and horsepower.

    Crankshaft Main Bearings

    • Crankshaft main bearings are found in between your engine block and your crankshaft. These are also the bearings on which the crankshafts rotate. Different types of engines have a different number of main bearings. For example, modern V8 engines have five main bearings while six cylinder engines have seven main bearings. The oil film coating around the bearings is important to keep consistent to ensure the crankshafts continue to spin.

    Camshaft Bearings

    • Camshaft bearings are used to reduce friction with the rotation of the camshafts. Camshafts (referred to as cams) are long rods with various lobes sticking out that can either cover or uncover a valve in the engine. Opening and closing these valves control how much air or fuel is available for combustion. The camshaft is connected to the crankshaft directly or by a gear mechanism so that the timing of both engine parts is in sync.

    How to Check Trailer Wheel Bearings

        Driving with a trailer increases your risk factors, due in part to the reduced braking and cornering of your vehicle. One way to mitigate this risk is to always ensure your trailer is operating in proper mechanical order. The trailer's wheel bearings are often neglected because they are out of sight. It is not until they begin to squeak or there is dangerous wheel shutter that owners tend to take notice. Unfortunately, this can sometimes be too late because a wheel bearing can fail quickly, leaving you stranded on the side of the road.


    Instructions

      • 1

        Chock the opposite side wheel and jack the trailer's axle up with the car jack. Place the jack stand under the axle and lock it into a position which will support the tire in a raised position. Lower and remove the car jack.

      • 2

        Remove the bolts which secure the rim to the axle with the socket set and remove the wheel. Pry the protective cap off the end of the axle with a slotted screw driver.

      • Remove the cotter pin which locks the end bolt in place. Loosen the nut which secures hub to the axle and then slide the hub off.

      • 4

        Remove the two bearings from each end of the hub. Inspect the bearings for abnormal wear. If the individual bearings are loose in their sockets or there is obvious damage replace with new bearings. Also inspect the hub for any grooving or damage and replace as necessary.

      • 5

        Apply new grease to the hub assembly and push grease into the bearing. Reassemble the bearing and hub assembly. Grease hub with grease gun using the nipple on the end of the hub.
