Enduro Bearings 3801 LLU - ABEC 3 MAX BO - Double Row Ball Bearing - 12x21x8mm

Maximum load capacity and reliable protection for high-performance mtb suspensions

ABEC 3 MAX double-row radial bearings with a 12 mm inner diameter, 21 mm outer diameter, 8 mm width, and a double-lip seal with strong contact, running in a groove similar to a labyrinth seal. 

The Enduro Bearings MAX bearing was specifically developed for the high loads encountered at the pivot points of modern mountain bike suspensions. With its special MAX design, double-row construction, and high-quality sealing, it offers high load capacity, reliable guidance, and a long service life—even under demanding conditions. Enduro Bearings developed the MAX bearings over 20 years ago specifically to meet the demands of mountain bike suspension joints. The particularity of the design allows for a higher number of balls than in conventional bearings. Combined with the deep raceway grooves, this ensures improved support against the high and fluctuating forces that occur at the suspension pivot points. The high-quality seal and generous grease fill help protect against the elements and contribute to a lengthened, reliable service life.

Features of the Enduro Bearings 3801 LLU - ABEC 3 MAX - Double-row ball bearings 

• Up to 35–40% higher load capacity compared to conventional angular contact ball bearings thanks to the special MAX design with an increased number of balls.
• Two-row design: Reduces flex in the suspension joint and doubles the bearing’s contact area.
• Deep raceway grooves: Improve lateral support under torsional forces and multidirectional loads.
• Grade 10 balls: For precise and reliable bearing performance.
• LLU double-lip seals: Full-contact labyrinth seals effectively protect against dirt, moisture, and other external influences.
• 90% filling with Almagard Extra High-Pressure Grease: Supports reliable lubrication and protects the bearing components.
• Black oxide coating: Increases corrosion resistance and promotes a long service life.
