Deep Groove Ball Bearings 6203

Description

Dimension standards Boundary dimensions: ISO 15 Snap rings and grooves: ISO 464 Tolerances For additional information → Tolerances Normal P6 or P5 on request Except for SKF Explorer bearings: Dimensional tolerances to P6 and tighter width tolerance: D ≤ 110 mm → 0/ –60 μm D > 110 mm → 0/ –100 μm Run-out: D ≤ 52 mm → P5 52 mm < D ≤ 110 mm → P6 D > 110 mm → Normal Except for small bearings in the 618 and 619 series, which comply to P6 tolerances. Refer to the technical specifications for each bearing (product table). Values: ISO 492 (table 1, table 2, table 3) Internal clearance For additional information → Internal clearance Single bearings and matched bearing pairs arranged in tandem Normal Check availability of C2, C3, C4, C5, reduced ranges of standard clearance classes or partitions of adjacent classes. Except for bearings with suffix JEM: C3 Values: ISO 5753-1 (table 4) Values are valid for unmounted bearings under zero measuring load. Matched bearing pairs arranged back-to-back or face-to-face Supplied either with clearance or preload: CA – small axial internal clearance GA – light preload Values: (table 5) Values are valid for unmounted bearing sets under zero measuring load. Permissible misalignment Single bearings ≈ 2 to 10 minutes of arc Misalignment increases bearing noise and reduces bearing service life, and when it exceeds the guideline values these effects become particularly noticeable. Matched bearing pairs Any misalignment increases bearing noise and reduces bearing service life. For additional information, contact the SKF application engineering service.
