Designation and Installation
n Refer to the following table
Retention screws with self-retaining thread inserts secure the bearing components during transport: loosen the retention screws during fitting in order to facilitate centring of the bearing;retighten or remove the retention screws after fitting of the bearing.
n The L-section ring (inner ring) of YRT bearings can be fitted either with or without additional support (Figure 2)
a)L-section ring without support – bearing designation YRT
b)L-section ring with support – bearing designation YRT..VSP.
The entire end face of the L-shaped ring must be supported.
n The L-section ring and support ring must be fixed with the same screw connection. The support ring (e.g. worm wheel) must be ordered separately.
n When dimensioning the drive for YRT bearings it should be noted that the frictional torque can increase by a factor of between 2 and 2.5 with increasing speed.
