Enduro Bearings Angular Contact Ball Bearing 7900 10 mm x 22 mm x 6 mm

Maximum number of balls in the angular contact ball bearing: the 7900 MAX from Enduro Bearings

MAX bearings are characterised by a 35 to 40 % higher load capacity than standard radial bearings. For 20 years Enduro Bearings has been manufacturing them specifically for use on mountain bike shocks. As its name indicates, MAX bearings are fitted with the maximum possible number of balls. The grooves in the races are deeper to accommodate the multiple lateral turning forces at the MTB rear pivot.
In standard radial bearings, only 3 or 4 balls make contact during the load at any given time. Inside of Enduro Bearings' Angular Contact (A/C) bearings, ALL balls are engaged so that they can distribute force over a larger surface area. This reduces friction and minimizes wear.

Versions with 2RS seal (type 1) and with 1ZS seal (type 2) are available.

Features:

• Angular contact ball bearing with 15° angle
• MAX = maximum number of balls, without cage or partitions
• 35 % higher load carrying capacity than standard bearings, turn less easily
• race grooves made of carbon-chrome steel alloy, heat and triple cold treated (down to -190° C), minimum hardness Rockwell HRC 62, polished
• chrome steel balls 10th degree = circularity is 10/1,000,000"
