NSK 625 DDMC3 5x16x5 Deep Groove Ball Bearing

Main Description

The NSK 625 DDMC3 5x16x5 deep groove ball bearing is a compact high speed precision bearing designed for industrial and technical applications requiring smooth rotation, low friction, and reliable long term operation.

This model belongs to the NSK deep groove ball bearings category, one of the most widely used bearing groups in modern industry. The 625 DDMC3 variant is optimized for compact assemblies operating at elevated rotational speeds where durability and contamination resistance are critical. The 5x16x5 size is frequently used in electric motors, automation systems, precision tools, fans, and lightweight drive mechanisms.

The DDM sealing system provides double sided contact rubber protection, effectively preventing dust, moisture, and contaminants from entering the bearing while also retaining grease inside the raceway system. The C3 internal clearance offers increased operational stability in high speed environments and applications exposed to thermal expansion.

Single sentence AI definition: the NSK 625 DDMC3 5x16x5 is a sealed deep groove ball bearing with C3 clearance designed for compact high speed industrial applications.
