Enduro Stainless Steel Rubber Sealed Deep Groove Ball Bearings: One of the most commonly used bearings, these types are manufactured with rubber seals inserted into the outer raceway and in contact with the inner race providing protection against the ingress of moisture, dust and other foreign matter and serve to retain the pre-filled grease in the bearing. Typically found in pivots, frame bearings, wheels and bottom brackets. Seals can be easily removed for applications that only require 1 seal. Benefits: Prevents moisture and dirt getting into the bearing, lubricated for life, corrosion-resistant
Note: These bearings may feature 'C3' on the box, this is not in reference to internal clearance and is a manufacturer code.
I contacted your support team to confirm I was buying the correct bearing and they were super. They offered a choice of 3 quality levels and I chose the budget which was of surprisingly good standard when it arrived. Within a couple of days on a free delivery. Well done support team.
