It restricts relative movement to reduce the load placed on the part and the machine. But there are different types of bearings, including plain, ball, roller, fluid and magnetic. The most basic type, plain bearings consist of a flat surface without any balls or rollers.

There are many types of bearings, each used for different purposes. These include ball bearings, roller bearings, ball thrust bearings, roller thrust bearings and tapered roller thrust bearings. Ball bearings , as shown below, are probably the most common type of bearing. They are found in everything from inline skates to hard drives.

We produce a broad range of precision ball bearings, wide inner ring ball bearings and housed units for standard industrial applications and specialized uses. From standard single-row deep groove radial ball bearings to advanced integral designs, Timken has your solution.

How Bearings Work

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly e. As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.

Catalog excerpts

Должно быть, это какая-то ошибка. Следопыт показывал адрес, не имеющий никакого смысла. Взяв себя в руки, она перечитала сообщение. Это была та же информация, которую получил Стратмор, когда сам запустил Следопыта. Тогда они оба подумали, что он где-то допустил ошибку, но сейчас-то она знала, что действовала правильно. Тем не менее информация на экране казалась невероятной: NDAKOTA ETDOSHISHA. EDU - ЕТ? - спросила Сьюзан.

Вызовите мне машину. Мужчина достал мобильник, сказал несколько слов и выключил телефон. - Veinte minutos, - сказал. -Двадцать минут? - переспросил Беккер.  - Yel autobus. Охранник пожал плечами. - Через сорок пять минут.

Сьюзан удалось протиснуть в щель плечо. Теперь ей стало удобнее толкать. Створки давили на плечо с неимоверной силой. Не успел Стратмор ее остановить, как она скользнула в образовавшийся проем. Он попытался что-то сказать, но Сьюзан была полна решимости. Ей хотелось поскорее оказаться в Третьем узле, и она достаточно хорошо изучила своего шефа, чтобы знать: Стратмор никуда не уйдет, пока она не разыщет ключ, спрятанный где-то в компьютере Хейла.

Он хотел отдать кольцо. Какие же страшные были у него руки.

 - Надеюсь, удача не оставит. Беккер опустился на колени на холодный каменный пол и низко наклонил голову. Человек, сидевший рядом, посмотрел на него в недоумении: так не принято было вести себя в храме Божьем. - Enferno, - извиняясь, сказал Беккер.

 Боже всемилостивый, - прошептал Джабба. Камера вдруг повернулась к укрытию Халохота.

Bearings are mechanical assemblies that consist of rolling elements and usually inner and outer races which are used for rotating or linear shaft applications, and there are several different types of bearings, including ball and roller bearings, linear bearings, as well as mounted versions that may use either rolling element bearings or plain bearings.
