SKF Ball Bearing, Deep-Groove Bearing Type, Shielded, 4mm ID, 9mm OD - 638/4-2Z


Use this single-row deep-groove ball bearing from SKF to ensure your light-load to medium-load applications perform effectively. It handles axial and radial loads in both directions to reduce wear on shafts and limiting downtimes. The unit minimises friction, which in turn curbs noise and vibration to support high rotational speeds. Integrated double-ended shielding helps to seal in lubricants while keeping contaminants out, to extend the service life of the bearing and save time on maintenance. A light weight of just 1.3g item adds minimal strain to installations.

• Sealed unit is suitable for outdoor applications
• Robust bearing steel for durability and heavy-duty use
• Non-contact seals enable friction-free movement
• Limiting speed of 70,000 rotations per minute for high-speed and very-high-speed systems

Applications


• Agricultural machinery
• Centrifugal pumps
• Transmission systems
• Domestic appliances
• Office equipment

How do I choose the right deep-groove ball bearing?


When choosing a ball bearing, you first need to match the bearing's inner diameter to your shaft. You also need to know the size of load the bearing can handle and it must be able to accommodate the rotational speed of your application.
