RBY205 Spherical Insert Bearing 25x52x34.1mm Self-aligning Bearing For Light Industry & Mini Grain Conveying Equipment

• RBY205 is a compact spherical insert ball bearing with double-side extended inner ring and dual grub screw locking design, fully interchangeable with standard YAR205-2F bearing, overall dimension 25×52×34.1mm. It adopts double lip rubber seal plus built-in grease nipple, featuring excellent dustproof performance and automatic self-aligning capacity relying on spherical outer ring. Made of premium GCr15 chrome bearing steel, it runs smoothly under light and medium radial loads.

  This bearing is categorized under Self Aligning Ball Bearing only for internal store classification management. Its appearance and internal structure are different from standard double row self-aligning ball bearings. It is widely used in small conveyor systems, textile, food and packaging machinery, and also suitable for auxiliary rotating parts of mini light agricultural conveying equipment. With nearly 30 years bearing manufacturing experience, GQZ supplies abundant stock, fast delivery and flexible OEM customization.
