 Specifications:

 ABEC 3 steel ball bearing with 9mm inner diameter, 24mm 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 following 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 labrinth seal. “2RS” literally means “Two Rubber Seals”
