The Igus M250 series plain bearings require a relatively large amount of bearing clearance for optimal operation. This ensures that the bearing bushings work reliably even when they expand due to an increase in temperature or absorb water. The bearings are designed for press-fit into a housing machined to a H7 tolerance. After the bearing has been installed in a housing with nominal dimensions, the inner diameter automatically adjusts itself in accordance with the specified D11 tolerance.
