Are these parts compatible only with SJ Petro ZJ40 Z05011400069AA Rotary Table Beam? Can they be used for other ZJ40 rotary table beam models?

All parts listed are exclusively matched to the SJ Petro ZJ40 Z05011400069AA Rotary Table Beam, ensuring 100% compatibility with the original equipment. They cannot be directly used for other ZJ40 rotary table beam models, as different models have differences in structural dimensions, load-bearing capacity, and connection positions. Using these parts for other models will cause installation mismatch, load concentration, and structural damage. For other ZJ40 rotary table beam models, provide the specific beam model number, and we will offer matching genuine accessories.

What is the recommended service life of key components (e.g., Z05011400069AA Rotary Table Beam, Z01141000001AA Fixed Seat), and how to extend it?

Under normal drill site operation conditions, the recommended service life is 24 months for Z05011400069AA Rotary Table Beam, 12 months for Z01141000001AA Fixed Seat, and 18 months for Z05011700212AA Welding Beam. To extend service life: 1. Adhere to monthly weld inspection and weekly lubrication requirements; 2. Clean all components regularly to maintain anti-corrosion performance; 3. Avoid overloading, uneven load, and accidental impact; 4. Replace worn parts in time and use only genuine accessories.

How to confirm the correct part when procuring, especially if multiple parts have the same name (e.g., Vertical Plate) but different models?

The key to ensuring correct procurement is to use the original product model (e.g., P6111532AA vs. P6042405AA Vertical Plate)—each model is uniquely designed for specific positions and load requirements on the rotary table beam, even for parts with the same name. If unsure, provide the beam model (Z05011400069AA), part name, and installation position. Our technical team will confirm the correct model, avoiding procurement errors that lead to operational failures or safety hazards.
