Spindle bearings

Spindle bearings are single-row angular contact ball bearings that consist of one-piece outer and inner rings and ball-cage assemblies having one-piece window cages. They are not demountable. The bearings are available in open and sealed versions. Spindle bearings have restricted tolerances for abutment dimensions and radial runout accuracy. They are particularly suitable for bearings with the highest requirements regarding guide accuracy and suitability for high speeds. They have proven their worth when it comes to carrying spindles in machine tools.

Identifying and repairing rolling bearing damage
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.

Sealed spindle bearings: ABEG® impresses with its efficiency

The requirements for rolling bearings differ considerably depending on the area of application. In woodworking, for example, cutting forces for chipping are lower than in metalworking, such that spindle bearings in milling spindles need to achieve high speeds, but they do not have to deal with very high forces. Spindle bearings in the ABEG® performance class Supra can replace premium products in many applications, which makes it an economical alternative with the same technical suitability.
