In the case of less interference, can be pressed at room temperature with sleeve TIMKEN bearing ring face, using hammer tapping sleeves, rings balanced through the sleeve is pushed. If the mass installation, to be used in hydraulic presses. When pressed, should guarantee the outer ring side face and the shell shoulder end surface, inner ring and shaft shoulder end surface clamping, gaps are not allowed.
Such TIMKEN bearing outer rings are separable. Normal state, the inner and outer ring raceways and rollers should not be crushing, grinding deeper pits and mark; cage should be no deformation on the ring, and rollers can be full; inner and outer ring raceways and rollers clearance should not exceed 0.06mm.
TIMKEN bearing installation, you must exert equal pressure on the circumference of the ring face, ring is pushed, do not use tools such as hammer percussion bearing faces directly, in order to avoid damages TIMKEN bearings.
