55mm 1pcs Chrome Steel Bearing Ball G100 Precision Hardened (AISI52100)

Condition: 100% brand new In Stock: Yes Ball Diameter: 55mm Grade: G100 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% 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. Dimensional inspection: These are high precision balls, when checking the dimensions, please kindly use micrometer with accuracy at least +/-0.001mm, otherwise the measurement results will be compromised. 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. Packaging: Balls will be securely packed into a transparent plastic bag, then further protected with a bubble envelope or corrugated carton to ensure damage-free transit.

• 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: 55mm with diameter tolerance +/-0.01mm.
• 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: 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.
