FRW156zz Bearing Product Overview & Core Advantages
The FRW156zz is a single row ball bearing designed for high-performance applications requiring reliable radial load capacity and compact design. Manufactured to ABEC1 precision tolerances, this inch-series bearing features an extended inner ring for simplified axial location and a shielded design to retain lubrication and exclude contaminants. Its construction from chrome steel components ensures durability and consistent operation across a wide temperature range from -86 to 230 °F, making it a robust solution for precision mechanisms.
FRW156zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| zz | Indicates shielded construction on both sides. The 300 Series Stainless Steel shields protect the bearing interior from contamination while retaining lubricant, contributing to a longer service life. |
| Extended Inner Ring | The inner ring extends beyond the bearing width, facilitating easier mounting and axial positioning within an assembly. |
FRW156zz Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a stainless steel cage and 10 precision balls provides stable support and a radial dynamic load rating of 69 lbf, suitable for sustained radial loads.
- Precision & Speed: Built to ABEC1 tolerance standards with a controlled radial internal clearance (MC3), this bearing supports a limiting speed of 110,000 rpm, ideal for high-speed applications.
- Durability & Corrosion Resistance: Components made from chrome steel and a stainless steel cage offer excellent wear resistance. The shielded design helps maintain performance by protecting the internal geometry from debris.
- Compact & Lightweight: With an outside diameter of just 0.3125" and a weight of only 0.2 g, it is engineered for space-constrained and weight-sensitive designs.
FRW156zz Bearing Typical Application Areas
- Precision Instruments: Small motors, optical encoders, and medical devices requiring ABEC1 precision and compact bearing dimensions.
- High-Speed Spindles: Applications in small drills, CNC tooling, and dental handpieces that demand high limiting speed and reliability.
- Electronics & Robotics: Cooling fans, miniature gearboxes, and robotic joint assemblies where light weight and effective radial load support are critical.
