Stainless Steel Balls for Valves, Bearings and Measurement
REDHILL supplies precision stainless steel balls for measuring devices, bearings, valves and pumps. Each steel grade offers a different balance of hardness, wear resistance and corrosion resistance. Therefore, choose the material to match the fluid, contact load and operating temperature.
Applications of Stainless Steel Balls
Gauging and Measuring Devices
Gauge makers use precision balls as contact points and measurement references. For example, stainless steel spheres form part of ball bars and other inspection tools. Therefore, specify diameter accuracy, roundness and surface finish to suit the measurement.
Bearings and Precision Mechanisms
Hardened grades such as AISI 440C provide a hard, wear-resistant surface for rolling contact. As a result, engineers use these balls in bearings, guides and other moving parts. In addition, match the hardness and finish to the mating surfaces.
Valves and Pumps
Stainless steel balls act as closing elements in check valves, metering pumps and sprayers. However, sealing and pressure capacity depend on the complete valve design. Therefore, choose the ball material and finish for the seat, fluid and cleaning conditions.
Choosing a Stainless Steel Grade
- AISI 440C: High hardness and wear resistance after heat treatment.
- AISI 302 and 304: Good toughness and corrosion resistance for many industrial uses.
- AISI 316: Higher corrosion resistance than 304 in many process fluids.
However, the right choice depends on the actual fluid, temperature and cleaning method.
Sizes and Specifications
Specify the diameter, steel grade, precision grade, surface finish and quantity. In addition, include the working conditions and any special requirements.
