FRW3 W19 Bearing Product Overview & Core Advantages
The FRW3 W19 is a single row ball bearing designed for high-performance applications requiring reliable radial load capacity. Manufactured to ABEC1 precision tolerance standards, this inch-series bearing features an extended inner ring for simplified mounting and axial location. Its open design allows for versatile lubrication options, while the stainless steel cage ensures stable operation across the entire temperature range from -86 to 230 °F. The combination of chrome steel components and optimized ball geometry delivers exceptional durability in compact spaces.

FRW3 W19 Bearing Structural Features & Performance Benefits
Extended Inner Ring Design: The 0.2273" inner ring width provides increased contact surface for secure mounting and improved axial positioning accuracy. This feature is particularly valuable in applications requiring precise component alignment.
Optimized Ball Configuration: With 7 precision chrome steel balls of 0.0937" diameter arranged in a single row, the bearing achieves balanced load distribution and smooth rotational characteristics. The stainless steel cage maintains proper ball spacing even at the maximum limiting speed of 43,000 rpm.
Precision Manufacturing: Manufactured to ABEC1 tolerance class with MC3 radial internal clearance (0.00008" to 0.0005"), ensuring consistent performance and minimal vibration. The tight dimensional tolerances on bore diameter and outside diameter (-0.0003" to 0") guarantee reliable fit in precision assemblies.
High Load Capacity: The bearing delivers 249 lbf dynamic radial load rating and 88 lbf static radial load rating, making it suitable for applications requiring reliable performance under significant radial stresses.
