Brass Eccentric Wheel

An eccentric wheel is a wheel whose geometric center and rotating center are not at the same axis.
Its core function is to convert rotary motion into reciprocating linear motion or oscillating motion, used for pushing, clamping, triggering, driving, positioning and other functions.
A brass eccentric wheel is an eccentric wheel made of brass by upset forging. It is the most commonly used type of eccentric wheel.

1. High precision of eccentricity
Directly determines the movement stroke and positioning accuracy.
2. Strict dimensional and geometric tolerances
Roundness, coaxiality, and flatness ensure smooth operation without jitter or jamming.
3. High surface finish
Reduces friction, lowers noise, and improves wear resistance.
High wear resistance and self-lubrication of the material
4. Brass is the most suitable, as it resists wear and seizing during long-term operation.
5. High dynamic balance and operational stability
Ensures low vibration, low noise, and long service life at high speeds.

As a core component in precision transmission, eccentric wheels are most prone to issues such as inaccurate eccentricity, easy breakage, poor wear resistance, jitter, high noise, rusting and seizing.
Brass eccentric wheels perfectly solve these problems with their outstanding advantages.

Advantages of brass eccentric wheels include:
1. Dense structure & high strength
Upset forging refines the internal grain structure of brass, free from porosity and shrinkage, making it durable and resistant to fracture.
2. Excellent wear resistance & long service life
Uniform hardness after forging ensures minimal wear during long-term operation, with a service life far exceeding that of ordinary turned parts.
3. High dimensional accuracy & good consistency
Suitable for mass production; precise eccentricity guarantees smooth and stable operation without jitter.
4. Smooth surface, low friction & low noise
Small machining allowance after forging, smooth surface and good self-lubrication ensure quiet operation.
5. High material utilization & cost efficiency
Near-net-shape forming saves material and time, ideal for mass production of precision transmission parts.
The material and process for manufacturing eccentric wheels mainly depend on the application scenario. Carbon steel or stainless steel can also be used for other working conditions.

With excellent wear resistance, self-lubrication, stable operation and low noise, brass eccentric wheels are widely used in precision transmission, automation, valves, motors, home appliances, automobiles and other fields.

Typical applications include:
1. Valve Actuators: Solenoid valves, pneumatic valves, control valves, metering valves
2. Precision Instruments & Meters: Sensors, timing mechanisms, adjusting devices
3. Small Motors & Power Equipment: Micro motors, gear motors, vibration motors
4. Automation Equipment: Packaging machinery, textile machinery, printing machinery, automatic assembly machines
5. Home Appliances & Office Equipment: Small household appliances, massage equipment, precision actuators
6. Automotive Components: Automotive adjusting mechanisms, actuators, control units

At Shata Machinery, we use hot upset forging for preliminary forming + precision turning for precise machining to produce brass eccentric wheels.
Hot upset forging is a one-time hot forming process using a special mold with pressing machines, it is the first choice for medium-small brass parts with large order quantities, ensuring reliable quality and on-time delivery.
