What is a release bearing and the use of clutch release bearings Bearing ablation damage phenomena and common causes The release bearing is the bearing used between the clutch and the transmission. Usually, we call it “clutch release bearing”. When the clutch is stepped on, if the shift fork is combined with the clutch pressure […]

The history of bearings 1

The invention of the rolling bearing, in the form of wooden rollers supporting, or bearing, an object being moved is of great antiquity, and may predate the invention of the wheel.

Though it is often claimed that the Egyptians used roller bearings in the form of tree trunks under sleds, this is modern speculation. They are depicted in their own drawings in the tomb of Djehutihotep  as moving massive stone blocks on sledges with liquid-lubricated runners which would constitute a plain bearing. There are also Egyptian drawings of bearings used with hand drills

The earliest recovered example of a rolling element bearing is a wooden ball bearing supporting a rotating table from the remains of the Roman Nemi ships in Lake NemiItaly. The wrecks were dated to 40 BC.

Leonardo da Vinci incorporated drawings of ball bearings in his design for a helicopter around the year 1500. This is the first recorded use of bearings in an aerospace design. However, Agostino Ramelli is the first to have published sketches of roller and thrust bearings. An issue with ball and roller bearings is that the balls or rollers rub against each other causing additional friction which can be reduced by enclosing the balls or rollers within a cage. The captured, or caged, ball bearing was originally described by Galileo in the 17th century.

The first practical caged-roller bearing was invented in the mid-1740s by horologist John Harrison for his H3 marine timekeeper. This uses the bearing for a very limited oscillating motion but Harrison also used a similar bearing in a truly rotary application in a contemporaneous regulator clock.

Angular Contact Ball Bearings

  Supertembo offers one of the most comprehensive ranges of Angular Contact Ball Bearings designed to meet OE manufacturers’ demanding requirements. These bearings have a contact angle that enables them to withstand significant axial loads in one direction together with radial loads. They are generally used in pairs, triplex sets, quadruplex sets, or multiplex sets since an axial component […]

Self-Aligning Ball Bearings

    Thrust Ball Bearings are composed of a “washer-like” bearing ring with raceway grooves for the balls and are classified into flat seats or aligning seats. Designed to handle thrust loads while operating at high speeds, these ball bearings are able to sustain axial loads but no radial loads.   Available in two designs:  single direction and double direction. Single […]
