Unlike ball bearings, roller bearings have cylindrical rolling elements, which are particularly suitable for higher loads at relatively lower rotational speeds. The rollers provide a larger contact surface between the rolling element surface and the raceway than in the case of ball bearings. Because of this, the force transferred per unit area compared to a ball bearing decreases, resulting in higher load ratings. In turn, rollers have different rolling characteristics than balls. The increased warming due to the larger contact surface between the rolling element and the raceway especially limits the maximum rotational speed of roller bearings.
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.
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.
ZKL’s spherical roller bearings impress with their high reliability, even in heavy-duty applications, such as in the mining industry. The bearings consist of single-piece inner and outer rings as well as cage-guided barrel rollers. The inner rings are equipped with either cylindrical or tapered bores.
