The eccentric shaft and crankshaft are the core mechanical power components that drive the pistons in a reciprocating motion. They require high-strength and wear-resistant materials to ensure smooth operation even under heavy load.
Connecting rod – Part No.: 30213401 | Serial No.: 17 | Size: Ø58.3 × Ø15 × 83
Piston – Part No.: 30223370 | Serial No.: 18 | Size: Ø41
Piston assembly – Part No.: 30229795 | Serial No.: 16 | Size: Ø41
These precision-machined components ensure stable piston movement inside the cylinder and maintain high compression efficiency. Designed for long-term continuous operation in refrigeration systems.
Cylinder head – Part No.: 30236013 | Serial No.: 30 | Size: 165 × 123 × 43
Valve plate – Part No.: 30405909 | Serial No.: 33 | Size: Ø41
Both the cylinder head and valve plate are critical to compression efficiency and sealing performance. We also supply matching valve plate gaskets and cylinder head gaskets to maintain perfect sealing.
Crankcase bearing cover – Part No.: 30510741 | Serial No.: 10
Motor-end cover – Part No.: 30522901 | Serial No.: 55
Bearing sleeves – Part No.: 31111201 / 31112501 | Size: Ø40 × Ø36 × 30

Part No.: 34321901 — 200–260 V, 120 W
Part No.: 34321902 — 100–140 V, 120 W
Oil heaters prevent oil from thickening at low temperatures and ensure smooth circulation, protecting the compressor during start-up and operation in cold environments.
Terminal boards – Part No.: 34550015 / 34550401
Aluminum junction box – Part No.: 34350241 | Size: 206 × 136 × 73
Black plastic junction box – Part No.: 34350944 | Size: 202 × 95 × 57
Made from heat-resistant and corrosion-resistant materials, these electrical components ensure safe and reliable system connections.
Discharge shut-off valve – Part No.: 36131510 | Size: Ø16 – Ø14
Suction shut-off valve – Part No.: 36131512 | Size: Ø22 (7/8″)
Sight glass – Part No.: 36181501 | Size: Ø22 × 1 1/8″ – 18 UNEF
Used for piping connections, system monitoring, and maintenance operations.
