Fixed‑displacement low‑speed high‑torque radial piston motor. HMKB200 = Japanese domestic variant; HMB200 = global export counterpart, fully mechanically interchangeable.

Model Code Breakdown

1. HMKB200: Frame size 200, fixed‑displacement motor

2. J1 / J3 / J6: Mounting flange form

3. F: Flange‑mount shaft; M: Spline shaft

4. M3 / SM3: Main port housing configuration

5. V: Vertical‑up shaft orientation (adds extra drain port G¼” BSPF)Kawasaki P...

6. T: Built‑in multi‑disc static brake option

Variable‑displacement two‑speed equivalent: HMKC200 (same physical envelope, switchable 100 % / ~50 % displacement)Kawasaki H....

Core Design Features

• Hydrostatically balanced radial piston design, high volumetric & mechanical efficiency

• Excellent break‑away torque; smooth rotation at very low rpm

• Bi‑directional rotation capability

• Wide range of shaft, flange and port combinations

• Optional integrated spring‑applied hydraulic‑release brake for load‑holding (winch / marine applications)

• Optional flush valve for heavy‑duty cyclic duty‑cycles

Typical Application Scenarios

1. Marine: Anchor windlasses, mooring capstans, ship winches, deck cranes

2. Industrial: Injection‑molding machine screw drives, large reel unwinders / winders

3. Off‑highway & heavy machinery: Heavy winches, mining feeders, rotary drives

4. Material handling: Large slewing drives for heavy equipment

Critical Installation & Drain‑Port Guidelines

1. Case drain line: Must run directly to hydraulic tank, no teeing into main return line. Minimum internal bore ≥ 12 mm (½ inch) for drain runs up to 5 m; increase bore for longer runsKawasaki P....

2. Vertical‑shaft‑up mounting: Order model suffix V. Extra drain port required, fitted with 0.35 bar check‑valve to prevent siphoning and preserve bearing lubricationKawasaki P....

3. Vertical‑shaft‑down mounting: Drain piping must rise above motor casing level to avoid siphoning oil out of housingKawasaki P....

4. Mounting spigot clearance ≤ 0.15 mm. Use high‑strength mounting bolts with correct torque values.

5. Shaft coupling: Strict alignment required; avoid imposing radial / axial loads onto motor output shaft.

Fluid Compatibility

• Standard unit: Mineral hydraulic oils (ISO VG46 / VG68 recommended)

• For fire‑resistant fluids (HFC, HFDU): Special seal configuration must be specified at ordering.

• System filtration recommendation: ≤ 20 μm absolute filter.

Ordering Checklist

1. Complete full part number (HMKB200‑xxx‑xxx‑xxx)

2. Shaft type: Flange(F) / Spline(M)

3. Flange code (J1/J3/J6)

4. Port housing variant (M3 / SM3)

5. Shaft orientation: Horizontal / Vertical‑up(V) / Vertical‑down

6. Options: Built‑in brake, flush valve, special seals for non‑mineral oil

7. Application details (marine / industrial, duty cycle, pressure‑speed profile)

Common Fault Symptoms & Hints

• Slow rotation / low torque: Check system pressure setting, internal wear, contamination

• Excessive case drain flow: Piston / cylinder wear, service overhaul required

• External shaft‑seal leakage: Excessive case back‑pressure, damaged seal, shaft surface damage
