ABEC 3 steel ball bearing with 27mm inner diameter, 53mm outer diameter, 7mm thickness and LLB seal.
ABEC 3 precision bearings with Grade 10 steel balls and cryogenically treated chrome steel bodies.
LLB sealing system - two sealing lips on each sealant, which ride in a corresponding groove in the inner race to make a labyrinth seal.
The outer sealing lip repels dirt/water, while the inner seal retains grease. These seals essentially form a “Hydromatic Grease Seal” when in operation, the grease forming a barrier in the groove.
The letters after the bearing number designate the type of seals that are used in the bearing. “LLB” is a double lip type seal that makes light contact and also passes through a groove that forms a labyrinth seal. “LLB” literally stands for “Two Rubber Seals”
