Enduro Sealed Cartridge - High-Performance Replacement Bicycle Bearings

Sealed cartridge radial bearings — precision, durability, all-weather protection

High-performance ABEC-3 radial bearings engineered for demanding bicycle and light fitness applications. Designed with C3 clearance and deep-groove races to accommodate large balls, these sealed cartridge bearings deliver smooth rolling performance, long life, and reliable service under daily abuse and exposure to the elements.

Features include Grade 10 balls, dual-lip LLB seals that ride in a micro-groove to form a full labyrinth, and 90% fill with high-pressure waterproof grease for superior contamination resistance and low friction. The robust sealing system and grease fill help bearings resist water, grit, and road debris so your hubs, pivots and bottom brackets keep spinning freely.

Available in multiple material options — high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD15 with ceramic or stainless balls — to match your riding style and environmental needs. For suspension pivots, a MAX-type bearing is recommended where higher impact and articulation demands exist.

Engineered with the deepest possible groove races to maximize ball size and load capacity, these bearings provide dependable performance for hub bearings, pivot points, older square-taper bottom brackets and various exercise bike applications. Durable construction and meticulous sealing make them an excellent choice for replacement or upgrade when smoothness, longevity and weather resistance matter.
