• Lubrication and sealing must also be provided by the installation.
• The inner race is keyed to the shaft. The outer race has positive n6 tolerance, to give a press fit in a H7 housing.
• Additional side notches in the outer race provide for positive torque transmission.
• If the housing is to K6 tolerance, use of the notches is not necessary, but the housing must be strong enough to not expand after assembly.
