Selecting XSA bearings

Bore, outside diameter, height and pilot dimensions
Fixing-hole layout and allowable load on the bolted joint
Gear module, tooth count, quality and backlash at the pinion

Compare XSI for internal teeth or XSU for a gearless arrangement. Confirm which diameter each A/B/C/D symbol represents on the relevant drawing. Compare the related series.

Individual model pages are being added. Use the series table or send the complete model number and drawing for review.
