SSF1405.50CWHII Sany Original Factory Rotation Support | Material Code: 13484728
Original Factory Manufacturer: Sany Sote Transmission (SANY self-researched SSF single row four-point contact internal tooth turntable)
I. Compatible Models
Dedicated to: SY365H, SY375H, SY395H National IV Excavators (equipped with Hengli HVME400 distribution valve as original machine, main models of 36-ton class)
Not interchangeable with old SY360 Kawasaki configuration turntables.
II. Model Explanation SSF1405.50CWHII
- SSF: Single row four-point contact ball, internal tooth type rotation support (standard excavator structure)
- 1405: Raceway center diameter φ1405mm
- 50: Ball diameter 50mm
- CWHII: Sealing structure + reinforced quenched gear ring second-generation improved version
III. Key Specification Parameters
1. Gear: Internal tooth, module M10, total 90 teeth (meshing with small gear of rotation reducer)
2. Outer Ring Fixing Holes: 35 installation bolt holes; Inner Ring Installation Holes: 40 bolt holes
3. Material: 50Mn forging, raceway + tooth surface medium frequency integral quenching, original factory carburizing wear-resistant process
4. Sealing: Three dustproof + oil seal combination, CWHII improved mud and water leakage prevention structure
IV. Installation Position
Between the upper frame and lower chassis, connecting the rotation reducer and upper assembly, bearing the whole machine's axial force, radial force, and overturning moment.
V. Product Functions
1. Support the cab, counterweight, and boom assembly, enabling the whole machine to rotate 360°;
2. Internal tooth meshing rotation motor reducer, transmitting rotation torque;
3. Four-point contact balls simultaneously withstand the composite load of pulling, pressing, and flipping during excavator digging.
VI. Common Faults
1. Excessive turntable clearance and rotation play: Ball/raceway wear, causing rotation wobble and material甩头;
2. Tooth surface chipping and breakage: Lack of lubrication, rotation impact jamming, and misalignment of reducer assembly;
3. Leakage from outer ring oil seal: Damaged dustproof ring allowing mud and sand ingress, leading to raceway rust and grease leakage.
VII. Original Factory & Aftermarket Differentiation
- Sany Original 13484728: Outer ring cast with SANY logo + model steel stamp, uniform tooth surface quenching, accompanied by original factory certificate;
- Aftermarket: No steel stamp, insufficient tooth surface hardness, easy to wear and exceed clearance after 3000 hours of heavy load.
