Schaeffler PNA Series Roller Bearing, 20mm Bore Diameter, 42mm Outside Diameter - PNA20/42-XL
This roller bearing is a needle-type aligning bearing designed to carry radial loads in Compact assemblies. It incorporates an inner ring with a parallel bore to support accurate shaft positioning and is intended for applications operating across a broad temperature range. The component is supplied as an outer cup and inner ring arrangement to simplify installation where alignment and constrained axial displacement are required.
Features and Benefits:
• 17,800r/min limiting speed for high-speed rotation capability
• 21,300N dynamic load rating for sustained radial load handling
• 30,500N static load rating for resistance to heavy static loading
• 5,400N fatigue load limit for predictable service life under cyclic loads
• 20mm race width enabling Compact axial packaging
• 21,300N dynamic load rating for sustained radial load handling
• 30,500N static load rating for resistance to heavy static loading
• 5,400N fatigue load limit for predictable service life under cyclic loads
• 20mm race width enabling Compact axial packaging
Applications
• Suitable for precision gearboxes with tight axial space
• Ideal for high-speed motor shafts requiring Compact bearings
• Used with indexing mechanisms needing radial alignment
• Can be used for machine tools where constrained axial play matters
• Suitable for actuators operating within temperature limits

• Suitable for actuators operating within temperature limits
What internal components control axial displacement?
The design limits axial movement via the inner ring width and specified minimum axial displacement Value of 0.5mm.
What are the permissible operating temperatures?
The bearing can be used from -20°C up to 100°C as specified for normal operation.
How should chamfer dimensions be accommodated on mating parts?
Mating shaft and housing should observe minimum chamfers of rmin 0.8mm and r1min 0.3mm respectively.
What flange and raceway interfaces must the housing provide?
The outer cup requires a flange diameter of 36.5mm while the inner raceway diameter is 25mm for correct seating.
