Spur gears are among the most widely used mechanical components for power and motion transmission. With teeth positioned parallel to the shaft axis, this type of gear is preferred in a wide range of machinery and industrial systems due to its simple design, high efficiency, durability, and versatility.

At Erdişli Makina, we manufacture spur gears for the specific requirements of various industries, based on technical drawings, existing samples, and customer-specified operating conditions. In addition to manufacturing new gears, we can reproduce worn or damaged gears used in existing machinery based on the original sample.

What Is a Spur Gear?

A spur gear, also known as a cylindrical spur gear, is a type of gear with teeth cut parallel to its axis of rotation. It is commonly used to transmit rotary motion and torque between two parallel shafts.

When manufactured with the right material selection, proper tooth geometry, and high-precision machining, spur gears provide efficient, durable, and reliable power transmission. For this reason, they are widely used across many industries, from machinery manufacturing and automation to heavy industry and production lines.

Erdişli Spur Gear Manufacturing

In gear manufacturing, dimensional accuracy alone is not enough. Tooth geometry, material selection, operating loads, and working conditions must all be evaluated together.

At Erdişli Makina, we manufacture spur gears in various diameters, modules, numbers of teeth, materials, and technical specifications according to customer requirements.

Our manufacturing capabilities range from a minimum diameter of Ø20 mm up to a maximum diameter of Ø1300 mm, enabling us to provide solutions for applications ranging from small machinery mechanisms to large-scale industrial systems.

Manufacturing from Technical Drawings or Samples

A technical drawing is not mandatory for production. When an existing gear sample is available, its dimensions and technical characteristics can be evaluated to manufacture a suitable replacement gear.

This capability allows us to provide replacement solutions particularly for discontinued machinery, older equipment, and systems requiring gears with non-standard dimensions.

Materials

The service life and performance of a spur gear are directly related to selecting the appropriate material for its operating conditions. Different materials can be selected depending on load, rotational speed, impact, operating duration, and environmental conditions.

Depending on application requirements, spur gears can be manufactured from:

• 4140

• 8620

• 1040

• 17CrNiMo6

• Bronze

• Cast Polyamide

• Aluminum

Other materials suitable for specific project requirements can also be evaluated.

Heat Treatment Options

For gears operating under high loads, surface hardness, wear resistance, and mechanical strength are critical factors. Appropriate heat treatment processes can be applied to manufactured spur gears according to application requirements.

Depending on production requirements, heat treatment methods such as carburizing, induction hardening, and nitriding can be applied. These processes are intended to improve tooth surface wear resistance and extend the service life of the gear.

Advantages of Spur Gears

When properly designed and manufactured, spur gears provide high mechanical efficiency. Their relatively simple construction also offers significant advantages in manufacturing, installation, and maintenance.

Key advantages include:

• High power and torque transmission capacity

• High mechanical efficiency

• Robust and durable construction

• Manufacturing flexibility across different diameters and modules

• Easy maintenance and replacement

• Efficient power transmission between parallel shafts

• Wide range of material options

• Suitability for a broad variety of machinery and industrial systems

Applications

Spur gears are used extensively across industrial applications, particularly in mechanical systems where motion or power needs to be transmitted between parallel shafts.

Typical applications include machinery manufacturing, production lines, conveyor systems, gearboxes, automation systems, agricultural machinery, packaging machinery, textile machinery, food processing machinery, metalworking equipment, and various other industrial systems.

Custom Spur Gear Manufacturing

Every machine operates under different conditions and requires different gear specifications. For this reason, in addition to standard solutions, we also provide custom spur gear manufacturing according to specific project requirements.

Gear diameter, module, number of teeth, hub design, keyway, bore diameter, material, and heat treatment specifications can all be determined according to the requirements of the application.

By manufacturing according to technical drawings or existing samples, we provide solutions particularly for maintenance, overhaul, and machinery spare-part requirements.

Why Erdişli Makina?

Since 1987, we have combined our experience in manufacturing machine gears and spare parts with modern manufacturing requirements.

With a production infrastructure capable of meeting a wide range of requirements, from small custom components to large industrial gears, we manufacture gears from Ø20 mm to Ø1300 mm based on technical drawings or existing samples.

Our goal is not simply to manufacture a gear, but to provide a reliable and long-lasting power transmission component engineered for the specific machine, operating conditions, and requirements of our customers.
