These loose bearing balls are made of durable low carbon steel AISI1015 and have a 3/8″ (9.525mm) diameter.
With a G100 precision grade, these carbon balls are ideal for general-purpose use on carts, conveyors, bicycles, and hobby projects.
They are ideal for bulk replacement or DIY repairs, especially in applications requiring high load capacity and toughness.
Application:
- Strong and impact-resistant for high-load applications
- Suitable for wheels, pulleys, and mechanical linkages
- G100 grade offers a good balance between cost and precision
- Common in bicycles, tools, and industrial hardware
Description of carbon steel ball
Material: AISI1010,1015,1020,1045,1085 available.
Sizes: 0.8mm to 3″(76.2mm)
Grades: Tolerances for carbon steel balls are ±0.0005 (grade 100) up to ±0.005 (grade 1000). G100,G200,G500,G1000 available.
Hardness: HRC58-62
Profile
Carbon steel balls Supply High hardness and excellent wear resistance,are an economical alternative to through-hardened precision balls. Carburized outer case, soft core, provides good load capacity, resistance to shock loads and surface wear. Non-heat treated carbon steel soft balls are also available applicated where the ball would need to be welded, modified, or drilled.
Hardness
Soft Carbon steel ball hardness at HRC10-30 deponds on the materials.Carbon steel balls are case-hardened to Rockwell C 60 minimum to provide strength and long life.
Applications:
Carbon steel balls are used in ball bearings to facilitate both linear and radial motion in applications from small equipment to industrial machinery.They provide reliable performance for less expensive anti-friction bearings, steering columns, casters, conveyors and trolleys, roller skates, toys and drawer slides,bicycles, roller skates, slides, trolleys and conveyors,Hinges,BB shot Carbon steel balls are also specified for vibratory finishing, stopper balls and aerosol cans, where ingredient mixing is required
