10,000-20,000 operating hours (standard conditions); proper maintenance and clean fluid can extend life to 30,000+ hours.

Use high-quality hydraulic filters (10 µm or finer), regularly replace fluid, keep reservoirs sealed, and avoid mixing different fluid types.

Yes--Rexroth supplies genuine replacement parts (seals, solenoids, spools, coils) globally; contact authorized distributors for fast sourcing.

Low temperatures thicken fluid (slower response); high temperatures degrade seals and reduce fluid viscosity (leaks, reduced control precision).

Yes--Rexroth offers compact, rugged models (with IP65/IP67 protection) designed for mobile equipment (excavators, tractors, trucks).
