German Brammer bearings Brammer models Brammer prices

Brammer bearings can simultaneously withstand radial and axial loads. They can operate at higher speeds. The larger the contact angle, the higher the axial load capacity. The contact angle is the angle between the line connecting the contact points of the ball and raceway in the radial plane and the perpendicular to the bearing axis. High-precision and high-speed bearings typically use a 15 degree contact angle. Under axial force, the contact angle increases.

Brammer bearing applications

Single-row angular contact ball bearings: machine tool spindles, high-frequency motors, gas turbines, centrifugal separators, front wheels of small cars, differential pinion shafts, booster pumps, drilling platforms, food machinery, indexing heads, repair welders, low-noise cooling towers, electromechanical equipment, painting equipment, machine tool T-slots, arc welders Double-row angular contact ball bearings: oil pumps, Roots blowers, air compressors, various transmissions, fuel injection pumps, printing machinery, planetary gearboxes, extraction equipment, cycloidal gearboxes, food packaging machinery, electric welders, soldering irons, junction boxes, gravity spray guns, wire stripping machines, half-shafts, inspection and analysis equipment, fine chemical machinery.

Brammer 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 bearings perform 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 speed.

Brammer bearing maintenance

1) When the bearing has operated for a certain period (or during the maintenance interval), remove all bearings; 2) Soak and clean the bearings with diesel or kerosene; if technical conditions allow, open the seals for cleaning; 3) After cleaning, let the cleaning oil air dry, and visually inspect for damage; 4) Use a wooden rod (preferably a hollow tube) approximately 150mm long, with a diameter equal to the inner diameter of the angular contact ball bearing, fixed with 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 and melt an appropriate amount of lubricating 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 maximum residual grease. Determine the amount of residual grease as needed. 9) Wipe the external grease off the bearings with a soft cloth or toilet paper, and assemble the FAG bearings back onto the pulley in their original state to complete the maintenance work.
