Explore our certified heavy-duty petroleum drilling components, components manufactured with precision.
In modern hydrocarbon exploration and heavy engineering hoisting operations, Roller Bearing Sheaves are essential mechanics. Under intense operational stresses, crown blocks and traveling blocks demand minimal rotational friction coupled with maximum radial and thrust load capacity. Utilizing precision-configured tapered roller bearings or cylindrical roller bearings within steel sheaves is paramount to ensuring safe lifting profiles and preventing catastrophic wire rope degradation.
From the deep wells of the Permian Basin to off-shore drilling platforms in the North Sea, these sheaves run continuously under millions of pounds of static hook load. Replacing standard journal bushings with high-grade roller bearings significantly reduces mechanical wear. This reduces fuel consumption on drawworks, decreases wire rope replacement intervals, and avoids structural failures in mast systems.
Advancing structural integrity and rope lifespan through metallurgy and bearing configuration.
Unlike cast sheaves prone to internal porosity, MTPM utilizes forged structural steel. Precision-machined wire rope grooves undergo induction hardening (ranging from 35 to 45 HRC) at a controlled depth. This minimizes abrasive wear on the crown block and traveling block wire lines.
By incorporating double-row tapered roller bearings with specialized labyrinths and synthetic lip seals, MTPM sheaves remain fully sealed from external mud, sand, and ocean brine. This directly prevents catastrophic seize-ups in sub-zero or high-desert installations.
Certified lifting capacities mandate compliance with industry certifications. MTPM sheaves are rigorously engineered and tested to API 8C specifications, guaranteeing structural load capacity rating and material traceability for global drilling safety mandates.
Your Trusted API Certified Oilfield Equipment Partner Since 2003
Was established on July 15, 2003, and is headquartered in Baoji City, Shaanxi Province, sharing location advantages with industry pioneer BOMCO. As a leading manufacturer of petroleum machinery and components, we were among the first outstanding enterprises in our local industry to begin exporting our products and engage in both import and export business. For many years, we have dedicated ourselves to manufacturing high-quality petroleum machinery and supplying reliable products and technical services to drilling companies and oilfield equipment traders worldwide.
Our quality management system is strictly implemented, ensuring rigorous inspections at every stage, from raw material procurement to final product delivery, to provide customers with high-quality, high-performance products.
MTPM is an API Authorized Manufacturer. We have obtained API Monograms for API-7K (Mud Pump and Drawworks Components), API-8C (Hoisting Sheaves), and API-11D1 (Downhole Equipment) since 2014.
MTPM is an authorized and recognized supplier of high-quality replacement parts for leading drilling equipment brands such as BOMCO, HONGHUA, RG, LANSHI (LSNOV), and DFXK.
Engineered precision. Proven oilfield lifespan.
Witness the precision engineering and certification backing every product.
Three core tenets that define our industry leadership in petroleum components manufacturing.
We focus on research and development as well as innovation, focusing on the precision manufacturing of mud pumps and spare parts, fully covering the drilling rig components used throughout the oil drilling, exploration, and production process. Currently, we hold 16 proprietary Chinese patents and have obtained 3 API certificates, including 7K, 8C, and 11D1, which significantly enhance the reliability and durability of our products, strengthening their competitiveness in the market.
The company operates a modern manufacturing facility spanning 5,000 square meters, equipped with over 80 advanced production machines and testing & inspection equipment, ensuring efficient, large-scale, and standardized production. Our team includes more than ten highly skilled technical professionals with extensive industry expertise. Additionally, our core team has been with the company for over 15 years, providing strong support for technological innovation.
Our company is an approved supplier for BOMCO, LS Group, and Honghua. Additionally, our products are widely supplied to drilling companies under CNPC and Sinopec, as well as their major subsidiary oilfields. We have successfully expanded into international markets across Europe, the Americas, Africa, Central Asia, and the Middle East. Through long-term and stable partnerships with well-known enterprises worldwide, we have built a strong reputation in the industry.
Comprehensive integrations for Crown Blocks, Traveling Blocks, and Masts.
Every drilling rig hoisting mechanism functions as a dynamic system. Forged steel sheaves fitted with specialized roller bearings cannot operate in isolation; they must align perfectly within traveling blocks, crown blocks, and mast structures to avoid fleet angle issues. If the sheaves have even a minor alignment deviation, wire rope wear increases exponentially, shortening the working lifespan of expensive drilling lines.
MTPM Solutions: Our engineering division supplies complete replacement crown block sheave assemblies and deadline sheave assemblies. By controlling the heat treatment processes, groove polishing, and bearing fit in-house, we deliver components that are 100% interchangeable with major drilling rig brands such as BOMCO, Honghua, and Lanshi (LSNOV). This facilitates straightforward replacement workflows, lowering operational overhead during field maintenance intervals.
