SKF Blue Line Stainless Steel Insert Bearing

40 X 80 X 49.2 / 21(Food grade H1 Grease)

The bearing is designed as a single row deep groove ball bearing with a sphered (convex) outer surface to the outer ring. The sphered surface matches a correspondingly sphered, but concave housing bore. The design minimises internal loads on the bearing that would exist if initial misalignment went uncorrected.

The bearing inner ring is extended on the outboard/locking side. It is locked on the shaft with two stainless steel grub screws that are positioned at 120°, minimising inner ring distortion while maintaining good gripping strength. The inner ring of the bearing is dimensioned to accommodate the fitting of the back seal, allowing the units to be deployed in applications with the highest hygienic design and food safety requirements (e.g. open food processing zones). The sealing system consists of a non-contacting seal and a flinger, located at the outer circumference (fig 1). The flinger provides the first barrier against the ingress of both solid and liquid contaminants. This closes against the bearing outer ring when pressure washed.

Next, the design provides a series of internal concentric “gutters” (fig. 2) which contain and collect any drops of detergent that penetrate and then guide them, circumferentially, around and away from the bearing (fig. 3).

Due to this innovative design, the sealing performance is not limited by the lip contact force against the shaft. This means that the seal can achieve high levels of protection coupled with low energy consumption. The internal gutters are designed to guide detergent away from the bearing. Whereas the aim of a detergent is to penetrate and clean, this novel approach aims to work with rather than against the detergent.
