Materials

Cages are used to position and keep the balls distanced from each other at the pitch circle diameter. We offer a variety of different cage architecture and material tailor for each customer application. Cages are constructed of brass, steel, or synthetic materials. Brass and steel cages are manufactured at WIB. We also manufacturing our own tooling and can adapt cage designs to meet the requirements of the application. For certain applications, ball bearings without cages or full complemented bearings are manufactured.

Packaging is a very important parameter for the retention of the bearing quality during transport and storage. It is designed to protect the bearings against corrosion, dust, and other pollutants. Apart from that, each unit is labeled and carries all the relevant information concerning the technical and quality features of the bearing. The production batch number is printed on the label and guarantees the traceability of the product, as well as the identification of the manufacturing date. Therefore, it is advisable to unpack the ball bearing only prior to use or assembly.

The noise level is an important quality criteria of a ball bearing. It mainly depends on the following factors: precision of the geometric forms surface finish of the raceway and the balls cleanliness of the bearing type of lubricant type of cage rotational speed

It is even possible to apply a coating on the outer ring, before assembling the bearing, thus guaranteeing the best possible geometrical forms. The machining of grooves ensures that the coating perfectly adheres to the metal surface. Additionally, a wider temperature range may be covered.
