The 69 series belongs to the narrow-profile flanged bearing category, designed primarily for applications where a large inner diameter is required but the outer diameter is constrained. This series accommodates larger shaft diameters, while the integrated flange allows for positioning against the surrounding structure, eliminating the need for bulky bearing housings.
Bearing Features
Precision grinding optimizes the surface wear resistance of the SUS316 material—even under conditions of limited lubrication—while the flange provides an additional heat dissipation path, helping to minimize temperature rise during continuous, high-load operation. Visually, the bearings feature the distinctive silvery metallic finish of SUS316, conveying a sense of high-end precision; furthermore, the flatness of the flange surface prevents fluid accumulation at installation gaps, thereby reducing areas where bacteria could proliferate.
