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 sheave holes 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.

Frequently Asked Questions
Q
What drilling rig models are compatible with your heavy duty sheaves?
Our sheaves are engineered for high interchangeability and can be adapted to rig models ranging from 1000 HP to 3000 HP, including major OEM brands such as BOMCO, LS NOV, Honghua, RG, RONGSHENG, and EMSCO.
Q
What material is the sheave body made of, and what are its advantages?
The sheave body is manufactured from 42CrMo forged steel. This alloy provides superior tensile strength and fatigue resistance, ensuring uniform load distribution and long-term structural integrity under the continuous mechanical stress of drilling operations.
Q
What international standards and third-party certifications do your sheaves meet?
Our heavy duty sheaves are produced in strict compliance with API 8C standards. Third-party witness inspections and certification reports are available from Bureau Veritas (BV), CCS, ABS, SJS, and other recognized international certification bodies upon request.
Q
What is the expected service life of the sheave under normal field conditions?
Under normal drilling conditions with periodic bearing and groove maintenance, our sheaves are designed for a service life of 8 to 10 years. Consistent preventive maintenance is the key factor in maximizing component longevity and minimizing unplanned downtime.
Q
How does the sealed bearing system protect against harsh drilling environments?
Each sheave is fitted with tapered roller bearings featuring double-sealed protection, which effectively blocks infiltration from drilling mud, dust, and moisture. This design maintains smooth rotation under heavy load and significantly reduces the risk of premature bearing failure in demanding field conditions.
Q
Can you supply sheaves to match specific OEM part numbers or custom specifications?
Yes. As a source manufacturer with full production traceability from raw material to final inspection, we support custom specifications and OEM part number cross-referencing. Please contact our sales team with your rig model, rope diameter, load requirements, and any applicable part numbers, and we will provide a tailored technical solution.
