6.2 Storing the axial piston unit
• Storage areas should be free of corrosive materials and gases.
• To prevent damage to the seals, do not operate ozone-forming devices
(e.g.mercury-vapor lamps, high-voltage equipment, electric motors, sources of
electrical sparks and/or electrical discharge) in storage areas.
• Storage areas should be dry.
Recommended relative humidity ≤ 60%.
• Ideal bearing temperature: +5 °C to +20 °C.
• Minimum storage temperature: −50 °C.
• Maximum storage temperature: +60 °C.
• Keep out of direct sunlight.
• Do not stack axial piston units and store them in a shock-proof manner.
• Do not store the axial piston unit on the drive shaft or assembled parts,
e.g.sensors or valves.
• For further storage conditions, seeTable 7.
▶ Check the axial piston unit monthly to ensure proper storage.
The axial piston units come in corrosion protection packaging
(corrosionprotectionfilm) provided at the factory.
Table 7 lists the maximum permissible storage times for an unpackaged axial piston
unit as per datasheet90312.

The warranty will be voided if the requirements and storage conditions are not
observed or after expiration of the max. storage time (seeTable 7).
How to proceed once the max. storage time elapses:
1. Check the entire axial piston unit for damage and corrosion prior to installation.
2. Perform a test run to check the axial piston unit for proper functioning and
leak-tightness.
3. If storage time exceeds 24 months, replace the shaft seal.
Once the max. storage time has elapsed, we recommend that you have the axial
piston unit checked by your BoschRexroth service partner.
