7/64" (2.778mm) 2000pcs Chrome Steel Bearing Balls G10 Precision Hardened (AISI52100)

Condition: 100% brand new In Stock: Yes Ball Diameter: 7/64" (2.778mm) Grade : 10 Ball Material: Chrome steel AISI52100/1.3505/100Cr6/GCr15/SUJ2 Features : AISI type 52100 chrome steel bearing balls have excellent surface quality and dimensional precision. They offer superior wear resistance, high hardness (Rockwell C 60-66) and high load bearing capacity as a result of through-hardening. Chrome steel is a chrome alloy carbon steel, not a chrome plated steel. It's approximately 95% iron. Carbon = 0.95 - 1.1% Chromium = 1.3 - 1.6% Relative magnetic permeability ( µ ): Ferromagnetic > 300 General Uses & Applications: : These chrome steel balls are widely used in precision bearings, automotive components (brakes, steering, line shaft), bicycle, agitators, appliances, sliders, quick couplings, machine tool, lock mechanisms, conveyor belts, skates, pens, pumps, castors, measurement instruments, valves. Balls are environmentally friendly non-toxic. Please be rest assured to use! Warm Tips: : 1. Dimension check: These are very precision balls, when you check the dimension, please kindly use micrometer with accuracy at least +/-0.001mm, otherwise the test results are likely to be inaccurate. 2. Magnet: Since these balls are approximately 95% iron, they can be attracted by magnet. But they are not magnet balls themselves nor magnetized, they couldn't be used as magnet purpose. 3. Package: Balls will be nicely packed into transparent plastic bag, then with bubble envelop or carton for protection outside.

• Material: Low alloy martensitic chrome steel AISI 52100/ Gcr15. They offer superior wear resistance, high load bearing capacity, excellent surface quality and dimensional precision.
• Size: 7/64" (2.778mm) with diameter tolerance +/-0.0001".
• Hardness: HRC 60-66, hardened.
• Applications: Precision bearings, linear guide rail, ball screws, bicycle, scooters, skates, castors, sliders, automotive components (brakes, steering, line shaft), quick couplings, lock mechanisms, conveyor belts, measurement instruments, valves etc.
• Features: very small size; They can be attracted by magnet, but they are not magnet balls themselves nor magnetized; Widely used where high hardness is important, but corrosion resistance is not.
