Product DescriptionProduct Description| BALLSProduct RangeThe production site specialises in the manufacture of 0.3~100mm corrosion resistantsteel balls, chrome steel balls, stainlesssteel balls, copper balls and aluminium balls. Featureshigh hardness, wear resistance, smooth surface, good roundness, not easy to rust.ApplicationsWidely used in high-speed bottom noise bearings, motors, hardware, wrought iron, machinery parts, bicycles, motorcycles, automobiles, precision instruments, medical equipment, fishing gear, toys, rails, universal ball, luggage, electronics industry, also Can be used as a grinding media. Commonly used in precision equipment such as ball screw, slider guide, linear bearing.Specification| ACCURACYThe precision level of steel balls is typically measured in terms of their dimensional accuracy and surface finish. The international standard used to specify the precision level of steel balls is ISO 3290.ISO 3290 provides a classification system for steel balls based on their dimensional tolerances. The standard defines several grades, ranging from G10 to G1000, with G10 being the highest precision level. The G10 grade indicates that the diameter of the ball has a tolerance of ±0.25 micrometers.Here is a breakdown of the ISO 3290 grades and their corresponding dimensional toleranceG10±0.25 micrometersG16±0.4 micrometersG25±0.5 micrometersG40±0.8 micrometersG60±1.2 micrometersG100±2.5 micrometersG200±5.0 micrometersG500±12.5 micrometersG1000±25.0 micrometersIt's worth noting that higher precision levels require tighter dimensional tolerances, resulting in more accurate and consistent ball sizes. This precision is important in applications like bearings, valves, measurement instruments, and precision machinery where the balls need to fit precisely and provide reliable performance. | OTHER BEARING COMPONENTSClick to the corresponding pages∨CYLINDRICAL ROLLERSPHERICAL ROLLERTAPERED ROLLERCylindrical rolling elements with line contact to rings. Offers strong radial load capacity and high speed, but no major axial load. Used in heavy machinery like rolling mills...Drum/spherical double-row rollers with self-aligning ability (1.5°–2.5° misalignment allowed). Bears heavy radial + bidirectional axial loads. Used in crushers, ball mills...Frustum-shaped rollers matching tapered raceways. Bears both radial and axial loads; used in pairs for balance. Common in car hubs, machine tool spindles.NEEDLE ROLLERCAGEBEARING RINGSlender (diameter <5mm, length/diameter >3) with dense line contact. Saves space, offers strong radial load. Used in gearboxes, hydraulic pumps...Separates and guides rolling elements to reduce friction. Made of metal (steel/copper) or polymer (nylon 66). Prevents roller scattering during assembly...Annular parts (inner for shafts, outer for housings) with precision raceways. Made of 100Cr6 steel (61–65HRC); ensures load transfer and long bearing life...Company Profile| PRODUCTION SITE WorkersThere are 60 employees, including 15 technicians perfectly and strictly implement the production management system and supportthe specialized R&D capability of Granville.CapacityThe production site specialises in the manufacture of 0.3~100mm corrosion resistant steel balls, chrome steel balls, stainless steel balls, copper balls and aluminium balls; With 30 million annual output value for different materials of balls, we successfully engadged in automotive parts, mechanicaltransmission parts, hardware, defense,and other industries.CertificationsGranville management system has been qualified by the IS09001:2015.
