If the Bearing 7220 KOYO is not to be used immediately, it should be stored in a clean, dry place which is vibration free. Temperature should be stabilised to -20°C to +40°C. Eyebolts and/or lifting trunnions supplied with the Bearing 7220 KOYO should be screwed down until its shoulder is firmly against the face of the stator frame to be lifted. Eyebolts are normally designed for a vertical lift. Where two eyebolts are used with inclined loading, the maximum safe working loads of the table on page 10 (approximate weights) should not be exceeded.
