FRW133 Bearing Product Overview & Core Advantages
The FRW133 is a high-precision, single row ball bearing designed for demanding applications requiring compact size and reliable performance. Manufactured to ABEC1 precision tolerance standards, this bearing is engineered to handle radial loads efficiently. Its extended inner ring design facilitates easier mounting and integration into compact assemblies, making it an ideal choice for applications where space is at a premium and high reliability is essential.
FRW133 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| FRW133 | The base model number indicating the specific bearing size and series. |
| Open (Seal Type) | The bearing is unsealed (Open), requiring external lubrication and suitable for clean environments or applications where specific lubricants are applied. |
| Extended Inner Ring | Features a longer inner ring for secure axial location and simplified mounting. |
FRW133 Bearing Structural Features & Performance Benefits
- High-Precision Construction: Built to ABEC1 tolerance class with a MC3 radial internal clearance (0.00008" to 0.0005"), ensuring smooth, low-vibration operation essential for precision mechanisms.
- Optimized Load Capacity: Engineered with 10 chrome steel balls and a stainless steel cage to provide a dynamic load rating of 28 lbf and a static load rating of 10 lbf, delivering reliable performance under radial loads.
- Robust Material Selection: Components made from chrome steel (rings and balls) and a stainless steel cage offer excellent durability and corrosion resistance for long service life.
- Compact & Lightweight Design: With a bore diameter of 0.09375" and a width of just 0.0625", it is ideal for space-constrained applications, weighing only 0.21 grams.
- Wide Operating Range: Suitable for a temperature range from -86 to 230 °F, making it versatile for various environmental conditions.
FRW133 Bearing Typical Application Areas
- Precision Instruments and optical devices requiring minimal vibration and high rotational accuracy.
- Small Electric Motors and miniature gearboxes where compact size and reliable radial load support are critical.
- Medical Devices and laboratory equipment demanding high precision and cleanliness.
- Office Automation Equipment such as printers and scanners.
