RBY209 Insert Bearing 45x85x52.2mm Self Aligning Insert Ball Bearing Dustproof Design For Conveyor Packaging Textile Machinery

• RBY209 is an extended double-side inner ring spherical insert ball bearing with dual set screw locking structure, interchangeable with YAR209-2F standard bearing, overall dimension 45×85×52.2mm. Equipped with double lip rubber seal and relubrication grease nipple, it features reliable dustproof performance and excellent self-aligning capacity via spherical outer ring. Made of high-quality GCr15 bearing steel, it runs stably under medium load conditions.It is categorized under Self Aligning Ball Bearing group only for store classification management; its physical structure differs from standard double row self-aligning ball bearings. Mainly used for industrial conveyor systems, textile and packaging machinery, also applicable to light-duty agricultural conveying equipment. Backed by nearly 30 years bearing manufacturing experience, GQZ provides sufficient stock, fast delivery and OEM customization.
