Product Description
625RS Rubber Sealed Ball Bearing Miniature Bearing 5 x 16 x 5 mm is a type of bearing that can be used in various applications, such as robotics, 3D printers, automation projects, and scooters.
This bearing has a shielded design, indicated by the RS suffix, which means it has rubber seals on both sides. The seals help keep the lubricant inside and prevent dirt from entering the bearing. The bearing has a deep groove shape that allows it to support both radial and axial loads at high speeds.
The bearing’s races are made of steel, which gives them strength and durability. Steel also resists deformation when the bearing is under heavy loads.
Features:
- Part/Model: 625 2RS.
- Rubber sealed bearing.
- Deep groove geometry.
- Durable and resistant to deformation under heavy load.

Frequently Asked Questions
What does “RS” mean in 625RS?
The “RS” suffix indicates rubber seals on both sides of the bearing, which trap lubricant inside and block dust or moisture from entering, extending service life.
Can I use these bearings at high RPM?
Yes. The deep-groove design and steel construction allow reliable performance at high speeds, making them suitable for 3D printer axes and small motor applications.
Do these sealed bearings require regular lubrication?
No routine relubrication is needed. The integrated rubber seals retain factory grease, but you should inspect for seal damage periodically and replace the bearing if contamination is observed.
