Fushi Max 6903 Sealed Cartridge Bearing
ABEC 3 radial MAX bearing with 17mm inner diameter, 30mm outer diameter, 7mm thickness.
As most bicycles are built in pairs, it is the most economical to have 4 bearings in 1 pack.
Description: What are MAX bearings?
The MAX type bearings are specially designed for spring swivels.
With a special design where the maximum number of balls is inserted into the bearing, they have more load capacity than standard radial bearings,
The race grooves are deeper on these bearings for more lateral support for twisting and multiple forces connected with suspension swivel.
LLU or VRS double seals provide maximum protection against the elements while keeping the 80%-90% filling of Krupp or Mobil high pressure grease inside.
Features:
Class: ABEC 3 bearings use grade 10 chrome steel balls and 52100 high chromium steel races.
Balls: The high-precision balls are within 10/1,000,000 inch round, twice as round as the industry standard, at its high level.
Process: The steel breeds are made from a vacuum degassing process for the purest chrome steel.
Hardness: hardened to HRC-62.5, extremely tough and very durable.
Structure: the complete addition of the bearings, NO Retainer stands for toughness, up to 45% increased load capacity.
Testing: polished to a mirror surface for ABEC-3 precision and silent movement. 0.007 mm tolerances and noise tested.
Clearance: very difficult C2 small spacing, no horizontal swing, full manual preset.
