Technical specifications and applications

Main Description

The NSK 6805 DD ball bearing 25x37x7 is a precision-engineered, slim deep groove ball bearing designed for compact mechanical systems where installation space is limited. With dimensions 25x37x7, it provides reliable performance in applications requiring low profile components without compromising load capacity and rotational stability.

This model features DD double-sided rubber seals, which protect the rolling elements from dust, moisture and contaminants while retaining factory-applied lubrication inside the bearing. The sealed construction reduces maintenance requirements and extends operational life, making it suitable for continuous-duty industrial environments.

As a single-row deep groove ball bearing, the 6805 DD offers smooth rotation, low friction and stable load distribution. It is primarily designed for radial loads, while also supporting moderate axial loads in both directions. These characteristics make it widely used in electric motors, compact gear systems, automation equipment and light industrial machinery.

The slim-section design ensures compatibility with tight housing configurations and compact bearing units. It can be integrated into mechanical assemblies with bearing housings and drive components requiring precise alignment and dependable performance. High manufacturing standards ensure dimensional accuracy, consistent running performance and long-term durability.

The NSK 6805 DD 25x37x7 ball bearing is a dependable solution for OEM production, maintenance operations and industrial applications where reliability, efficiency and extended service life are essential.
