Dimension standards

Not standardized

Bore and outside diameter for many bearings: diameter series 9 or 0 (ISO 15)

Tolerances

For additional information → Tolerances

  • P6 尺寸公差
  • P5 级几何公差

Values: ISO 492 (table 1, table 2 and table 3)

Radial internal clearance

For additional information → Bearing internal clearance

C3 or C4

Except for bearings with a helical groove in the inner ring(s) bore (feature G in the Design variant/feature → product table): C2


Values: ISO 5753-1


Values are valid for unmounted bearings under zero measuring load.

Permissible misalignment

Misalignment increases bearing noise and reduces bearing service life.

For bearing arrangements where misalignment cannot be avoided, contact the SKF application engineering service.

轴向许可位移图 1

S最大 → 产品表


内圈或外圈上无挡边的轴承,或内圈或外圈上仅有一个挡边的轴承,可以允许一定限度的轴向位移。 轴相对于轴承座的位移发生在这些轴承内。 因此几乎不增加摩擦。
