How to Choose the Right Bearing: SFL vs. MKFL vs. MUFL
When selecting a square flange bearing, it’s essential to choose the right type to ensure optimal performance, secure mounting, and minimal maintenance for your application. Below is a comparison guide to help you decide whether an SFL, MKFL, or MUFL bearing is the best fit for your needs.
| Feature | SFL Bearing | MKFL Bearing | MUFL Bearing |
| Series | Standard 200 Series | Set screw locking | Eccentric locking collar |
| Mounting Style | Standard fit | Set screw tightening | Eccentric locking mechanism |
| Shaft Grip | Basic support | Strong hold with set screws | Extra-secure grip with eccentric collar |
| Misalignment Tolerance | Self-aligning | Moderate | High |
| Resistance to Slippage | Moderate | High | Very high |
| Best for... | General applications | Medium-duty machinery | High-torque or high-vibration environments |
Which Bearing is Right for You?
SFL Bearings – Versatile and Cost-Effective for General Use
- Best for standard industrial applications where precise shaft locking is not required.
- Ideal for conveyors, fans, and general machinery.
- Offers self-aligning capabilities for minor misalignment compensation.
- Choose SFL bearings if you need a reliable and budget-friendly flange bearing for moderate loads and general-purpose use.
MKFL Bearings – Set Screw for a Secure Hold
- Designed for medium-duty applications where additional shaft security is needed.
- The set screw mechanism locks onto the shaft, reducing movement and improving stability.
- Suitable for automation, light machinery, and material handling equipment.
- Choose MKFL bearings if you need a stronger shaft hold and more secure positioning than a standard SFL bearing.
MUFL Bearings – High-Torque Applications with an Eccentric Locking Collar
- Provides the strongest shaft grip, making it perfect for high-vibration or high-torque environments.
- The eccentric collar minimizes shaft wear and prevents loosening.
- Recommended for agriculture, heavy machinery, and demanding industrial setups.
- Choose MUFL bearings if you need maximum shaft security and vibration resistance in demanding conditions.
