DIN is a German standard in which rolling bearings, for example, are also standardized.

Rolling bearings according to DIN 625 are bearings that are used to support shafts or axles in order to enable rotary motion with minimal friction loss. These bearings typically consist of two concentric rings (the inner ring and the outer ring) and a series of rolling elements (balls) arranged between the rings. The rolling elements roll between the rings and thus enable low-friction movement.

DIN 625 is a German industrial standard that defines the specifications and dimensions for deep groove ball bearings. Deep groove ball bearings are the most commonly used rolling bearings and are characterized by their ability to support both radial and axial loads in both directions.

Here are some key features of rolling bearings according to DIN 625:

1. Designs: The standard specifies various designs of deep groove ball bearings, including single-row and double-row bearings as well as variants with or without seals and covers.
2. Dimensions: DIN 625 specifies the exact dimensions of the bearings, including the outer diameter, inner diameter and width. This ensures that bearings from different manufacturers are interchangeable.
3. Materials: The standard also specifies the materials from which the bearings and rolling elements are made, usually high-strength steel.
4. Load capacity: The bearings are designed for different loads, and the standard specifies the maximum radial and axial loads that the bearing can withstand.

Deep groove ball bearings to DIN 625 are widely used in machinery and equipment, from household appliances and automotive applications to industrial machinery and equipment. They are very popular due to their versatility, their high load carrying capacity and their ability to achieve high speeds.

Numme­rie­rungs­sys­tem:

In der DIN 625 ist die inter­na­tio­nale Bezeich­nung für Rillen­ku­gel­la­ger festgelegt:

• 60xx – leichte Baureihe
• 62xx – mittlere Baureihe
• 63xx – schwere Baureihe

Example:

Ein 6204-Lager ist ein Rillen­ku­gel­la­ger mittle­rer Reihe mit einem Bohrungs­durch­mes­ser von 20 mm.
