SKF W 638/8 Series Ball Bearing, 8mm Inside Diameter, 16mm Outside Diameter - W 638/8-2Z
This ball bearing is a single-row sealed radial bearing designed to provide low-friction rotation for Compact assemblies in automation, electronics and mechanical systems. It combines corrosion-resistant construction with an integral sealing arrangement to support continuous rotational applications where space is limited and component durability is required.
Features & Benefits
• Stainless-steel raceways and balls deliver corrosion resistance and longevity
• Integral shields reduce contamination ingress for extended service life
• Limiting speed 45,000 rpm supports high-speed rotating components
• Dynamic load capacity 0.715 kN allows sustained operational loading
• Static load capacity 0.3 kN resists brinelling under installed loads
• Integral shields reduce contamination ingress for extended service life
• Limiting speed 45,000 rpm supports high-speed rotating components
• Dynamic load capacity 0.715 kN allows sustained operational loading
• Static load capacity 0.3 kN resists brinelling under installed loads
**Applications**
• Suitable for miniature motors in industrial automation
• Ideal for precision fans in electronic enclosures
• Used with rotary encoders and position sensors
• Can be used for small gearbox shafts in electrical drives
• Suitable for spindle assemblies in laboratory equipment

What bore Interface does it use for mounting on shafts?
It has a cylindrical inner bore requiring interference or location methods such as a snug fit with shaft shoulders or securing rings for axial positioning.
How is the bearing retained axially in Compact assemblies?
Axial retention is typically achieved by shoulders, circlips or end caps that bear against the outer ring faces while allowing free rotation.
How does the shielded end type influence lubrication needs?
Integral shields moderate lubricant egress and contaminant ingress, reducing maintenance frequency but still requiring appropriate grease selection for sustained high-speed service.
