Product Overview

The Sintered Gears are flagship powder metallurgy products from Zhida Powder Metallurgy, engineered as critical mechanical components and structural parts for high-efficiency power transmission systems. Leveraging advanced powder metallurgy technology, these gears deliver exceptional precision, durability, and cost-effectiveness—outperforming traditionally machined gears in demanding industrial applications.

Crafted through precision compaction and controlled sintering, our sintered gears feature a uniform, dense structure that ensures smooth meshing, low noise, and high load-bearing capacity. As a complementary mechanical component to our oil-impregnated bearing bushing lineup, they form integrated drive solutions that minimize friction and maximize energy efficiency. Compliant with international standards (ISO, DIN), these gears meet the rigorous requirements of automotive, industrial machinery, electronics, and consumer goods sectors—delivering reliable performance and reduced total ownership costs.

What sets our sintered gears apart is their near-net-shape production, which eliminates material waste and reduces secondary machining. The porous powder metallurgy structure also enables optional oil impregnation, enhancing self-lubrication and wear resistance for low-maintenance operation. Whether used in gearboxes, motors, or precision drive systems, these structural parts embody our commitment to producing high-quality powder metallurgy products that drive industrial innovation.

Product Features & Competitive Advantages

Our Sintered Gears outperform traditional machined gears and competitors’ offerings through innovative design and manufacturing:

1. Precision Engineering & Smooth Meshing

Advanced compaction and sintering ensure uniform tooth profile accuracy (ISO 6-9 class), enabling smooth meshing with minimal backlash (≤0.05mm for high-precision versions).
Strict dimensional control (CMM inspection) guarantees consistent performance across batches, reducing transmission errors in drive systems.
Helical and bevel gear options offer quiet operation (≤65dB) and improved load distribution compared to standard spur gears.

2. Durable & Wear-Resistant Construction

High-density powder metallurgy structure (6.8-7.4g/cm³) and optional heat treatment enhance tensile strength (≥350MPa) and wear resistance.
Corrosion-resistant material options (stainless steel, copper-based alloy) withstand moisture, chemicals, and outdoor exposure.
Optional oil-impregnated design leverages porous structure for self-lubrication, reducing friction and extending service life by 2-3 times.

3. Cost-Effective & Efficient Production

Near-net-shape manufacturing reduces material waste by 40% vs. traditional machining, lowering production costs without compromising quality.
Integrated design eliminates the need for assembly of multiple components, reducing labor costs and improving production efficiency.
Short lead times (2-4 weeks for standard orders) support just-in-time manufacturing strategies.

4. Versatile & Customizable

Wide range of gear types (spur, helical, bevel, planetary) and sizes to fit diverse transmission systems.
Customizable module, number of teeth, and face width to meet specific speed and torque requirements.
Compatible with our oil-impregnated bearing bushing lineup for integrated, low-maintenance drive solutions.
