The axial load carrying capacity of single row angular contact bearings depends on the contact angle α, with higher contact angles providing greater axial load capacity. Typical contact angles are 15°, 25°, and 40°.
Single row angular contact ball bearings generally use solid metal cages. In some high-speed applications, solid cages are typically made of phenolic resin, but they should not exceed a working temperature of 120°C. Rubber seals (RS/2RS) provide optimal sealing effectiveness but increase friction. Open bearings without seals are suitable for extremely high speeds and are easier to relubricate. However, they are more susceptible to contamination.
Standard preload for angular contact ball bearings is classified into three levels: light (L), medium (M), and heavy (H).
