Deep Groove Ball Bearings

Deep groove ball bearings are the most commonly used type of rolling bearings. In addition to radial forces, they can also absorb axial and combined forces and are particularly suitable for high speeds. Deep groove ball bearings cannot be disassembled and only allow a small tilting angle.

Standards

The general dimensions of single row deep groove ball bearings are standardised in ISO 15 (Radial bearings - Boundary dimensions, general plan), DIN 616 (Rolling bearings - Dimensions), and DIN 625-1 (Radial deep groove ball bearings). The dimensions of the circular groove and circlip correspond to ISO 464 (Radial bearings with snap ring), DIN 616, and DIN 5417 (Securing parts for rolling bearings - Snap rings for bearings with ring groove).

Dimensions and Tolerances

KRW supplies deep groove ball bearings with normal tolerance (PN) in accordance to DIN 620-2 (Tolerances for roller bearings) and ISO 492 (Radial bearings - Dimensional and geometrical tolerances). All other deviating or special tolerances must be specified with the order

Bearing Design

Deep groove ball bearings are non-latching bearings that cannot be disassembled. In addition to radial forces, they also absorb axial forces from both directions. Depending on bearing clearance, contact angles are adjusted in the process. The radial load limit for ball bearings is significantly lower than for roller bearings with line contact due to the point contact.
