# Shaft and Housing Fits That Keep Rings From Spinning

Loose shaft fits let the inner ring frett against the journal. Tight housing fits can crush clearance. The H7/m6 family and its neighbors exist so designers pick interference where rotation happens and clearance where the ring must float.

Field crews still mix up layout rules when drawings are thin. Cross-check the notes from bearing fits guide before the next change-out. TFL Bearing collects the practical checks in one place for maintenance and design review.

Keep Shandong TFL Bearing Co., Ltd bookmarked with the shaft drawing. Shandong TFL Bearing Co., Ltd publishes application notes so teams share the same language on fits, clearance, and locating ends.
