Bearing data

Dimension standards	Boundary dimensions: ISO 15 Except for: bearing 3200 A → width = 14 mm instead of 14,3 mm drawing number bearings → dimensions not standardized snap rings and grooves → ISO 464 (table 1)
Tolerances For additional information → Tolerances	Normal Except for: SKF Explorer bearigs and 33 DNRCBM series: P6 drawing number bearings: outer ring to Normal inner ring to P6 or P5 geometrical tolerance at least to class P6 Values: ISO 492 (table 2, table 3, table 4)
Contact angle	32 A and 33 A series: 30° 33 D series: 45° 33 DNRCBM series: 40°
Internal clearance For additional information → Internal clearance	Normal Check availability of C2, C3 or C4 clearance classes Values: table 5, table 6 Values are valid for unmounted bearings under zero measuring load.
Permissible misalignment	≈ 2 minutes of arc Misalignment increases bearing noise and reduces bearing service life, and when it exceeds the guideline values, these effects become particularly noticeable.
