Product Overview
The Omron R88M-K40030H-S2-Z is a 400 W Accurax G5 K-series AC servo motor with an oil seal, manufactured by Omron Corporation. Hengyixin Automation ships this drive from Xiamen with the matching motor or PSU pairing recommended in the related products row below.
It delivers 1.27 N.m of rated torque at 3000 r/min from a 200 V class winding, with a peak torque of 3.82 N.m (300 percent of rated) for acceleration. The 20-bit incremental encoder (131072 counts per turn) gives smooth low-speed torque. The straight shaft has a keyway and a tapped hole for pulley or pinion mounting.
The oil-seal suffix (-Z) is the only difference from the otherwise identical R88M-K40030H-S2. Pick the -S2-Z when the shaft couples to a gearbox, a sprocket, or any oil-lubricated load. Pick the bare -S2 when the load runs dry. Powers from an Accurax G5 drive, typically the R88D-KN04H-ECT for EtherCAT or R88D-KT04H for analog / pulse. The matching power cable is R88A-CAKAxxxSR-E; the encoder cable is R88A-CRKAxxxCR-E. The brake sibling is the R88M-K40030T-S2.

Best-Fit Applications
- Conveyor belt drive on a 400 W sorting conveyor where the oil seal keeps gearbox grease off the encoder bearings on the B-side coupling
- Index-table drive on a small assembly machine where the R88M-K40030H-S2-Z pairs with an R88D-KN04H-ECT drive and runs an EtherCAT motion profile
- Spare replacement on a packaging line where the previous R88M-K40030H-S2 is upgraded for the -Z (oil-seal) variant after a gearbox oil leak reached the shaft
Buying Checklist
- Pick the R88M-K40030H-S2-Z for a 400 W Accurax G5 servo motor with keyed shaft and oil seal on the 60 mm square flange.
- Pick the R88M-K40030H-S2 instead when the load is a dry coupling or a non-lubricated pulley and the oil seal is not needed.
- Pick the R88M-K40030T-S2 instead when the cabinet needs a 24 VDC holding brake on the same 400 W 3000 rpm motor.

FAQ for R88M-K40030H-S2-Z
What is the Omron R88M-K40030H-S2-Z used for?
It is the Accurax G5 K-series AC servo motor at 400 W, 3000 r/min, 200 V class, with a keyed shaft and an oil seal. It is the typical mid-power axis on packaging, material-handling, and small machine-tool machines that need a keyed shaft for a mounted pulley or pinion, and an oil seal to keep gearbox lubricant off the encoder bearings.
R88M-K40030H-S2-Z vs R88M-K40030H-S2 - what is the difference?
Both are the same 400 W, 3000 rpm, 200 V class motor with a keyed straight shaft on the 60 x 60 mm Accurax G5 flange. The -Z suffix adds the factory-installed oil seal; the bare -S2 has no oil seal. Pick the -Z when the shaft couples to a gearbox or any oil-lubricated load. Pick the bare -S2 when the load runs dry, the IP67 body rating is enough, and you want the lowest-cost 400 W G5 motor.
What drive pairs with the R88M-K40030H-S2-Z?
Any Accurax G5 400 W drive. For EtherCAT motion control, use the R88D-KN04H-ECT. For MECHATROLINK-II, use the R88D-KN04H-ML2. For analog / pulse command, use the R88D-KT04H. For a safety drive with hardwired STO, use the R88D-KN04H-ECT-Z or R88D-KT04H-Z. The matching power cable is the R88A-CAKAxxxSR-E; the matching encoder cable is the R88A-CRKAxxxCR-E.
Does the R88M-K40030H-S2-Z need a brake?
Not for typical horizontal loads (conveyors, indexers, feeders) where coast-down is acceptable. The H suffix means no holding brake. For vertical axes (Z-axis on a press loader, lift on a stacker crane, spring-loaded reel stands) that must hold position when de-energised, pick the R88M-K40030T-S2 (with 24 VDC brake). For the same 400 W motor with a brake plus oil seal, pick the R88M-K40030T-BS2-Z or contact Hengyixin for the matching brake plus oil-seal build.
