The B2 is a high-quality Ball Bearing Bearing with bore diameter of 15.0000 mm, outer diameter of 24.7000 mm, and width of 12.0000 mm.
Equipped with Double Sealed sealing, the B2 bearing offers effective protection against dust and moisture while retaining internal lubricant, reducing maintenance requirements.
With a dynamic radial load rating of 10 lbf and static load rating of 5 lbf, the B2 is engineered to handle demanding operating conditions.
- Reliable load capacity for general industrial applications
- Optimized operating speed for stable performance
- Double Sealed sealing for reduced maintenance and longer bearing life
- Precision manufacturing to ISO standards ensures consistent quality
- Fully interchangeable with major international brands (SKF, NSK, FAG, NTN)
The B2 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 B2 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 B2 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 B2 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.
