FRW155 Bearing Product Overview & Core Advantages
The FRW155 is a single row ball bearing designed for high-performance applications requiring precision and reliability. Engineered with an extended inner ring and manufactured to ABEC1 precision class, this bearing excels in handling radial loads efficiently. Its compact inch-series design makes it ideal for space-constrained assemblies, while its robust construction from chrome steel ensures durability and consistent operation. The bearing requires lubrication and operates effectively across a wide temperature range, making it a versatile component for demanding industrial environments.
FRW155 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| FRW155 | Base model number indicating specific dimensions and series. |
| Open (Seal Type) | No integral seals; requires external sealing for contaminated environments. |
| Extended Inner Ring | Facilitates easier mounting and axial location in assemblies. |

| MC3 | Specifies the radial internal clearance group for optimal performance. |
FRW155 Bearing Structural Features & Performance Benefits
Constructed with a single row design and a stainless steel cage, the FRW155 offers excellent rotational stability and is suitable for high-speed applications up to 53,000 rpm. The use of chrome steel for both rings and balls provides high hardness and wear resistance, contributing to a dynamic load rating of 69 lbf and extended service life. The extended inner ring enhances mounting precision and simplifies axial positioning. With a controlled radial internal clearance (MC3 group), this bearing ensures smooth operation and minimal vibration, which is critical for maintaining accuracy in precision machinery.
