The Enduro MR 17287 LLU/LLB CN ABEC-5 Radial Bearing is a high-performance 17x28x7mm bearing engineered for durability and smooth operation, ideal for hub applications and suitable for looser press-fit bores due to its CN clearance. It features deep-groove races with Grade 10 balls, protected by outward-facing dual-lip LLU seals for extreme element resistance and inward-facing LLB seals to retain 90% fill Mobil XHP 222 waterproof synthetic grease. This ABEC-5 bearing is designed with the deepest possible grooves to accommodate large balls and dual-lip seals that create a labyrinth for superior protection against contaminants.
