Bearings \u2013 Roller bearings and sliding bearings<\/h2>\n

[\/et_pb_text][et_pb_text admin_label=”History & Use and construction of roller bearings” _builder_version=”3.27.4″]<\/p>\n

The history<\/strong> of bearing is already more than 2000 years old, for example, in old Egypt, the heaviest boulders, for the construction of the pyramids or other cultic sites, were stored on simple wooden tracks to transport them over large distances. It was already ascertained that the required power was significantly lower when logs were used instead of the skids.<\/p>\n

In the 16th century, it was Leonardo da Vinci, who dealt scientifically with the topic of abrasion and developed determining insights into the function of rolling<\/strong> and sliding bearings<\/strong> – for example, the cage for the roller elements. The invention of the steam engine, at the beginning of the industrial revolution, brought the real breakthrough for the machine element bearings.<\/p>\n

Use and construction of roller bearings<\/h2>\n

Roller bearings<\/strong> are one of the most commonly used machine components today. Wherever loads are supported or guided, bearings are in use. So the essential functions are the transmission of movement and the transmission of forces. One distinguishes between sliding and rolling bearings. In sliding bearings, the power transmission and the rotational movement take place between so-called sliding surfaces.<\/p>\n

Roller bearings are composed of an inner ring, an outer ring and the roller elements arranged therebetween. These roller elements provide a low-friction movement and power transmission. Roller bearings are clearly superior to sliding bearings<\/strong>, especially in slow-turning applications.<\/p>\n

Ball bearings and roller bearings<\/h3>\n

Roller bearings<\/strong> can transmit forces in the radial and \/ or axial direction. Also a distinction is made between ball bearings and roller bearings. In ball bearings, the rolling element is a ball and in roller bearings a roller, a cylindrical roller, a barrel roller, a needle roller, a tapered roller or a flexible roller<\/strong>.<\/p>\n

[\/et_pb_text][et_pb_image src=”https:\/\/eich-rollenlager.de\/wp-content\/uploads\/2018\/07\/walzlager-eich-rollenlager.jpg” alt=”Roller bearing – Eich-Rollenlager” title_text=”Roller bearing – Eich-Rollenlager” align_tablet=”center” align_last_edited=”on|desktop” _builder_version=”3.23″][\/et_pb_image][et_pb_text admin_label=”Standard bearings or special bearings” _builder_version=”3.27.4″]<\/p>\n

Standard bearings or special bearings (Different types of roller bearings)<\/h2>\n

Basically, a distinction is made between roller bearings with point contact (ball bearings)<\/strong> and roller bearings with line contact<\/strong> (roller bearings)<\/strong>. Rolling bearings can also be differentiated according to the mode of loading, namely radial roller bearings and axial roller bearings. Some roller bearings are combined loadable.<\/p>\n

Nowadays rolling bearings<\/strong> are considered mature machine elements. DIN 611:2010-05 provides an overview of most types, individual parts, designations and the associated national and international standards. Further standards define e.g. the dimensions (DIN 616: 2000-06), the materials (DIN EN ISO 683-17: 2015-02) or the calculation (DIN 26281: 2010-11, DIN ISO 76: 2009-01). This regulatory framework then also describes and defines the performance parameters<\/strong> of the standard roller bearings, such as the operating conditions or the durability.<\/p>\n

Manufacture of special roller bearings<\/h3>\n

However, there are also limiting conditions that preclude the use of standard bearings, such as extreme operating conditions (high temperatures, high impact loads, etc.) or even geometric restrictions. In these cases, special roller bearings<\/strong> are used.<\/p>\n

This is the range in which Eich Rollenlager GmbH<\/a> has specialized and has now gathered over 75 years of experience<\/strong>. Eich has built up competencies and has established itself as a reliable partner for the industry. The slogan of the company Eich is: We develop bearings<\/strong> \/ solutions that become standards instead of the other way round.[\/et_pb_text][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner _builder_version=”3.25″ column_structure=”1_2,1_2″][et_pb_column_inner type=”1_2″ saved_specialty_column_type=”2_3″ _builder_version=”3.25″ custom_padding=”|||” custom_padding__hover=”|||”][et_pb_text admin_label=”Telefon” module_class=”kontakt-tel” _builder_version=”3.27.4″]<\/p>\n

3D measurement of rolling bearings<\/h2>\n

The bearings produced have to be measured again and again during production so that the dimensions are exactly right. The following video shows a quality control of a rolling bearing in the house of Eich Rollenlager GmbH<\/strong>. This is done using the latest measuring equipment and qualified employees.
