Product Features
✓
Each MTPM sheave is produced to sustain the mechanical stress of continuous drilling operations.
✓
The forged steel sheave body minimizes material fatigue while ensuring uniform strength distribution across the equipment.
✓
The optimized groove geometry provides steady rope guidance, reducing friction and extending wireline service life.
✓
Precision machined sheaves hole allow smooth rotation under heavy load, while the sealed bearing housing effectively prevents contamination from mud and dust.
✓
The surface coating system delivers durable corrosion protection, retaining its structural integrity and color stability even after prolonged field exposure.
As a source manufacturer, we supply sheaves fully compatible with major OEM equipment from BOMCO, LS NOV, Honghua, RG and other well-known drilling equipment brands. Customers can expect high interchangeability, strict compliance with API 8C requirements, and production traceability from raw material to final inspection.
