Design of bearing arrangements
To maximize the effectiveness of the insulation, SKF recommends the following guidelines for dimensioning the shaft and housing shoulders . For bearings with a coated outer ring (designation suffix VL0241, fig. 1), the abutment diameter in the housing should be ≥ Da min (→ product table). For bearings with a coated inner ring (designation suffix VL2071, fig. 2), the abutment diameter on the shaft should be ≤ da max (→ product table).
During mounting, INSOCOAT bearings should be handled in the same way as standard bearings. When using an induction heater, the INSOCOAT layer must not be damaged by the vibration of the heater. For bearings with a coated inner ring (designation suffix VL2071), use a protective sleeve or an additional support block made of plastic.
In cases where springs are used to apply preload or lock nuts are used for axial clamping, SKF recommends inserting a steel spacer ring between the bearing and the preload or locking device (fig. 3).
