6.2 Storing the axial piston unit
Requirements
• The storage areas must be free of corrosive materials and gases.
• To prevent damage to the seals, ozone-forming equipment (e.g. mercury-vapor
lamps, high voltage equipment, electric motors, sources of electrical sparks or
electrical discharge) must not be operated in storage areas.
• The storage areas must be dry.
Recommended relative humidity ≤ 60%.
• Ideal storage 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.
After delivery
The axial piston units are provided with corrosion protection packaging at the factory
(corrosion protection film).
Table 7 lists the maximum permissible storage times for an originally packed axial
piston unit as per data sheet 90312.
Table 7: Storage time with factory corrosion protection
Storage conditions
Closed, dry room, at an even
temperature between +5 °C
and +20 °C. Undamaged and
sealed corrosion protection
film.
Warranty is void if the requirements and storage conditions are not observed
or after expiration of the maximum storage time (see Table 7).
Procedure after expiration of the maximum storage time:
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 function and leak-
tightness.
3.
If the storage time exceeds 24 months, the shaft seal must be replaced.
After expiration of the maximum storage time, we recommend that you have the
axial piston unit inspected by your Bosch Rexroth service partner.
In the event of questions regarding repair and spare parts, contact your responsible
Bosch Rexroth service partner or the service department of the manufacturer's plant
for the axial piston unit, see chapter 10.5 "Spare parts" on page 54.
