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 equipment
(e.g.mercury-vapor lamps, high-voltage equipment, electric motors, sources of
electrical sparks 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 ashock-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 professional 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 datasheet 90312.
Table 7: Storage time with factory corrosion protection
Storage conditions Standard corrosion protection Long-term corrosion
protection (optional)
Closed, dry room, uniform
temperature between +5°C and
+20°C. Undamaged and closed
corrosion protection film.
Maximum 12 months Maximum 24 months
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 atest 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 BoschRexroth service partner.
For questions regarding repair and spare parts, contact your proper BoschRexroth
service partner or the service department of the manufacturer's plant of the
axial piston unit, see chapter 10.5 "Spare parts" on page 44.
