Interesting information about ball bearings

A history of rolling bearings

Rolling bearings make movement possible. They do this in a wide variety of ways because, when it comes to rolling elements, there are three different designs: balls, rollers and needles. Italian all-round genius Leonardo da Vinci is considered the father of today’s rolling bearing technology: In 1490, he drew the first sketch of a modern ball bearing. Instead of just lubricating the axle and wheel and inserting one into the other, he put a layer of balls between the two components, thereby practically re-inventing the wheel.

However, it was only about 300 years later that this idea started to be used on a massive scale; the ball race was "reinvented" in 1772 and tested in vehicles. Another groundbreaking innovation was the invention of the ball cage, which significantly increased the performance of bearings. Friedrich Fischer’s ball grinding machine enabled perfectly even circular grinding of hardened steel balls, even in large quantities. Fischer’s development laid the foundation for the modern rolling bearing industry.
Over the decades, it was possible to achieve continuous improvements in performance. Findling’s ABEG® method uses these different technology levels in order to offer optimal technical and economical solutions.

Deep-groove ball bearings of electric motor quality

Deep-groove ball bearings from the Xspeed series are specifically designed for use in electric motors and also deliver a convincing performance at high speeds with a particularly long service life..

The Xspeed bearings are designed for high-speed applications. Their use is therefore also recommended in pumps, compressors, fans, rotary encoders or air-conditioning systems. Since running properties play a special role in this segment, Xspeed bearings meet the highest requirements when it comes to the surface quality and profiling of the raceways. They are manufactured in tolerance class P6 with increased precision and radial runout accuracy. The bearing clearance is adapted to the high speeds by tightening the tolerance. This makes it possible to optionally adjust the residual bearing clearance based on the selection of the housing and shaft fit. For a particularly long service life, lubrication and seals were optimized with respect to the requirements of high-speed applications. A special high-purity, viscous and quiet grease with excellent start-up behavior ensures optimum operation at high speeds. The 2RSDD seal variant  (axially abutting contact rubber seal inserted into the groove on both sides) reduces the internal heating of the bearing by a whole 10 °C. An even lower-friction (2RW) variant and a non-contact seal variant (LLB) are optionally available.

Findling’s rolling bearing technology

As a specialist for rolling bearing technology, we offer a wide range of ball bearings in all ABEG® performance classes, such as single-row or double-row deep-groove or angular contact ball bearings, as well as thrust or radial bearings, magneto bearings, four-point contact bearings or self-aligning ball bearings, which can have a sealed or unsealed design and be made of a variety of materials. Ball bearings are the most frequently used products and are a particularly economical solution.

Identifying and repairing rolling bearing damage

Rolling bearing damage can have a wide variety of causes and is not necessarily caused by a faulty original product. However, most companies are unable to carry out a detailed damage analysis – good thing Findling Wälzlager’s experts can provide further assistance here: Damage analysis is part of the service portfolio. Findling Wälzlager acts as an independent partner that looks into the causes of the ball bearing defects and helps solve problems.

How do I know if I’ve chosen the right bearing clearance class – C0, CN, CM, C2, C3...? An article from our konstruktiv! series. Tips series.

It is not the load rating but the right overall technical specifications that are decisive when it comes to the service life and performance of roller bearings.

Radial bearing/thrust bearing

Combined radial/thrust bearings hold a special position among rolling bearings: They are capable of simultaneously handling very large radial and axial forces and are characterized by their particularly compact design. Findling Wälzlager offers combined bearings in a wide variety of designs and rolling member pairings.

Deep groove ball bearings

With its ABEG® eXtreme product family, Findling Wälzlager offers high performance that is paired a longer service life and fast delivery times at a very good price/performance ratio. One of the four available series is Xclean: Deep-groove ball bearings, self-aligning ball bearings, thrust bearings, needle-roller bearings and numerous other series are suitable for use in damp, corrosive or aggressive chemical environments.

Customers benefit from high quality

Thin-section bearings are great for solving problems in applications where there is little installation space, but only if they are selected and used professionally. Findling Wälzlager GmbH has built up special expertise in this regard. This allows typical problems to be avoided from the outset, and the customer benefits from consistently high quality standards, regardless of whether they’re in the standard or premium segments.

The right roller bearing selection

There are a lot of popular misconceptions when it comes to the selection of roller bearings. A good example of this is the myth regarding the load capacity of roller bearings: the specification of the load factor in the catalog and above all the overall correct technical specification are both crucial in determining the performance of a bearing. When making the right selection, the bearing clearance and fit also play a decisive role in addition to the cage.
