Fine Pitch Gearing

At Allied Sinterings, we leverage the capabilities of powder metal processing to manufacture premium quality, close tolerance, fine pitch gears. Our fine pitch gears provide precise rotational motion in applications where space is at a premium and performance is critical. We furnish precision fine pitch gears to companies with demanding quality criteria, such as medical device, automotive, industrial equipment, and consumer product manufacturers, among others.

As a precision gear manufacturing company, we specialize in producing miniature to small sized powdered metal gears with a diametral pitch up to 120. With our expertise in powder metallurgy, we attain repeatable dimensional accuracy when producing sintered metal gears with complex shapes and designs. All of our fine pitch gears, including spur gears, helical gears, and bevel gears, conform to AGMA Class 8 standards.

When reproducing the detailed geometry of a fine pitch gear or gear assembly, powdered metal processing offers advantages. We work with a variety of high purity metal powders, and we can blend powders to create unique alloy compositions that satisfy a specific set of performance criteria regarding strength, wear resistance, lubricity, and other material properties. Some examples of the materials we work with include brass, nickel steel, copper steel, stainless, and several others.

We produce fine pitch gears to near net shape. State of the art equipment and fully calibrated process monitoring provide accurate, repeatable results over thousands of cycles. The sintered parts have good surfaces and require minimal machining, and we offer resin impregnation to improve machinability or the surface qualities. For quality assurance, we use statistical process controls and high-end metrology equipment to ensure products conform exactly to customer specifications.

For companies considering a switch to powder metal processing for the production of fine pitch gears, we hold seminars to explain the benefits and outline the design constraints. Whether a fine pitch gear is used as part of a medical assembly, telecommunications device, or a high-performance power tool, powder metallurgy can save up to 70% over other manufacturing processes.
