Why Choose the 62203-2RS?

• Thickened Design: The extra-width 16 mm profile provides greater load capacity and enhanced structural integrity compared to standard-width bearings in the same bore size.
• Double Rubber Seals (2RS): Both sides are sealed with durable rubber to keep grease in and contaminants — dust, moisture, and debris — out, minimizing maintenance requirements.
• Deep Groove Raceway: Engineered to handle both radial and moderate axial loads, making it highly versatile for multi-directional force applications.
• Steel Construction: Manufactured from high-grade steel for excellent strength, wear resistance, and long service life.
• Value Pack: Comes as a convenient 2-piece set so you always have a spare on hand or can replace both sides of a shaft in one order.

Common Applications

• Electric motors and generators
• Gearboxes and transmissions
• Agricultural and farm machinery

Frequently Asked Questions

Q: What does "2RS" mean on the 62203-2RS bearing?

A: "2RS" stands for double rubber sealed — both sides of the bearing feature a rubber seal. This design keeps lubricating grease inside the bearing and prevents external contaminants such as dust and moisture from entering, making it ideal for applications where cleanliness and low-maintenance operation are important.

Q: What is the difference between a thickened 62203 and a standard 6203 bearing?

A: The standard 6203 bearing has dimensions of 17 x 40 x 12 mm, while the thickened 62203 measures 17 x 40 x 16 mm — a 4 mm wider inner ring and wider race. This extra width increases the bearing's load-carrying capacity and makes it a better fit for applications that demand greater axial and radial strength without requiring a larger bore or outer diameter.

Q: How many bearings are included in one order?

A: Each order includes 2 pieces (2 pcs/lot) of the 62203-2RS bearing, giving you a complete replacement pair for both sides of a shaft or a backup unit for future use.

Q: Is this bearing pre-lubricated?

A: Yes. The double rubber seals (2RS) are designed to retain factory-applied grease, so the bearing arrives ready to install without requiring additional lubrication in most standard applications.
