The 52305 is a high-quality Thrust Ball Bearing with bore diameter of 20.0000 mm, outer diameter of 52.0000 mm, and width of 34.0000 mm.
With a dynamic radial load rating of 7,762 lbf and static load rating of 13,500 lbf, the 52305 is engineered to handle demanding operating conditions. It supports speeds up to 5,000 rpm, making it suitable for high-speed applications.
- High load-carrying capacity (7,762 lbf dynamic) for extended service life
- Optimized operating speed for stable performance
- Open design for easy relubrication and low friction operation
- Precision manufacturing to ISO standards ensures consistent quality
- Fully interchangeable with major international brands (SKF, NSK, FAG, NTN)
The 52305 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 52305 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 52305 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 52305 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.
