German FLURO-Gelenklager bearings FLURO-Gelenklager models FLURO-Gelenklager prices

FLURO-Gelenklager bearings have raceways on both the inner and outer rings, and the inner and outer rings can move relative to each other along the bearing axis. This type of bearing is particularly suitable for withstanding combined loads, i.e., loads acting radially and axially at the same time. The axial load carrying capacity of angular contact ball bearings increases as the contact angle α increases. The contact angle is the angle between the line connecting the contact points of the ball and the raceway in the radial plane and the perpendicular to the bearing axis.

FLURO-Gelenklager bearing lubrication

The purposes of rolling bearing lubrication are to reduce internal friction and wear, prevent seizure; extend service life; dissipate frictional heat for cooling, prevent bearing overheating, and prevent lubricant aging; it also prevents foreign matter from entering the bearing interior, or prevents rust and corrosion. Bearing lubrication methods are divided into grease lubrication and oil lubrication. To ensure the bearing performs well, first select a lubrication method suitable for the operating conditions and purpose. If only lubrication is considered, oil lubrication has superior lubricity. However, grease lubrication has the advantage of simplifying the structure around the bearing. Compare the pros and cons of grease and oil lubrication. Pay special attention to the amount during lubrication; whether using oil or grease, too little leads to insufficient lubrication affecting bearing life, while too much creates significant resistance, affecting rotational speed.

FLURO-Gelenklager bearing maintenance

1) When the bearing has operated for a certain period (or maintenance interval), remove all bearings; 2) Soak and clean the bearings with diesel or kerosene; if technical conditions allow, open the seal covers for cleaning; 3) After cleaning, let the cleaning oil drain dry, and visually inspect for damage; 4) Use a wooden rod (preferably a hollow tube) about 150mm long, with a diameter equal to the inner diameter of the angular contact ball bearing, fix one bearing at one end; 5) While manually rotating the bearing quickly, press the other end of the wooden rod (tube) against your ear or an audio amplifier microphone to listen for bearing rotation noise; 6) After fixing the bearing, move the wooden rod laterally to check for wear or looseness; 7) FAG bearings with severe looseness, excessive rotation noise, or serious defects should be discarded and replaced with the same model; 8) Take a bucket, melt an appropriate amount of grease (high-quality yellow dry oil) over a gentle flame (do not overheat), immerse the inspected bearings in the bucket until no bubbles emerge. Remove the bearings before the grease cools for minimal residual grease. Remove the angular contact ball bearings after the grease cools for more residual grease. Determine the amount of residual grease as needed. 9) Wipe the grease off the outside of the bearing with a soft cloth or toilet paper, and assemble the FAG bearing back onto the pulley in its original state; maintenance work is then complete.
