The 52100 Chrome Steel Balls 0.0981 inch G10 is a precision ball-grade steel ball made from 52100 Chrome Steel. Manufactured to tight tolerances, it delivers consistent performance in bearing assemblies, automotive components, and precision instrumentation.
- Manufactured from high-hardness 52100 chrome steel for excellent wear resistance
- Tight dimensional tolerances ensure consistent performance across bearing assemblies
- Smooth surface finish minimizes friction and noise in precision applications
- Available in inch and metric sizes with multiple grade options (G5, G10, G20)
The 52100 Chrome Steel Balls 0.0981 inch G10 is available in Open (no seal), ZZ (metal shield), and 2RS (rubber seal) configurations. Open bearings offer higher speed ratings and lower friction, while sealed versions provide better contamination protection and reduced maintenance requirements.
JMP Bearings manufactures the 52100 Chrome Steel Balls 0.0981 inch G10 in various tolerance classes including ABEC-1 (standard), ABEC-3, ABEC-5 (precision), and ABEC-7 (high precision). Please contact us for specific tolerance class availability and pricing.
The 52100 Chrome Steel Balls 0.0981 inch G10 typically uses lithium-based grease (e.g., ISO VG 68) for general applications. For high-temperature or high-speed applications, synthetic greases such as polyurea-based lubricants are recommended. Contact our engineering team for application-specific lubrication guidance.
JMP Bearings offers flexible ordering - sample quantities are available from 1 piece. For bulk orders, we provide tiered pricing starting at 100, 500, and 1000+ pieces. Contact us for a custom quote tailored to your volume.
For standard 52100 Chrome Steel Balls 0.0981 inch G10 applications, shaft tolerance is typically k5 or j6, and housing tolerance is typically H7 or J6. Exact tolerance selections depend on load conditions, speed, and operating temperature. Refer to ISO 286 or consult our engineering support for detailed recommendations.
