How to choose the right F2 bearing for your application
Selecting the correct 2-bolt flange bearing (F2 bearing) is key to ensuring long-lasting, trouble-free operation and reduced maintenance costs. At BJ-Gear, we supply a complete range of high-quality F2 bearings — and we’re here to help you identify the best option for your equipment.
1. Determine your shaft diameter
The first step is matching the bearing to your shaft size.
Our F2 bearings cover Ø20 mm to Ø60 mm, making them suitable for everything from light conveyors to heavy industrial drives.
2. Consider your environment
Is your installation exposed to water, frequent cleaning, or aggressive media?
Our F2 bearings are designed for exactly these challenges, with:
Polyurethane housings in either black or blue, offering outstanding chemical and impact resistance.
Stainless steel inserts, ensuring high corrosion protection even in washdown or outdoor applications.
Nitrile rubber (NBR) seals, rated IP66/67, effectively blocking out water and dust.
The blue versions also feature steel-reinforced mounting holes, providing additional strength and stability — ideal for heavy loads or high vibration environments.
3. Check your mounting layout
All our F2 bearings use a 2-bolt flange design.
Be sure to verify the bolt hole spacing to ensure it fits directly into your existing setup. We stock multiple centre distances to accommodate a wide range of installations.
4. Select your locking system
Our bearings use an eccentric locking collar, a proven solution that ensures a secure, vibration-resistant fit. It’s simple to install and well-suited for applications with frequent starts and stops.
5. Plan for reliability and maintenance
F2 bearings from BJ-Gear are equipped with straight grease nipples, making it easy to perform periodic re-lubrication and extend bearing life as part of your planned maintenance.
