Bearing Assembly

Frequently Asked Questions

Q: What are the basic specifications of the 6203RS2 bearing?
A: The 6203RS2 is a deep groove ball bearing assembly with a standard 17 mm bore, 40 mm outside diameter, and 12 mm width. It features single rubber seals (RS designation) and is designed for manual pallet jack wheel and drive assemblies in standard industrial duty applications.

Q: What is the difference between 6203RS2 and double-sealed variants like 6203-2RS?
A: The 6203RS2 has single rubber seals (RS2 designation) compared to double-sealed versions (2RS or DDU). Single-seal bearings are lighter and may cost less but offer reduced contamination protection. They are suitable for dry warehouse environments but less ideal for wet storage or outdoor material handling.

Q: What material composition does the 6203RS2 use?
A: The 6203RS2 is constructed from high carbon chromium steel (similar to AISI 52100 equivalent) with pressed steel cage construction. These materials deliver reliable load-carrying capacity and durability for typical manual pallet jack operating speeds and loads.

Q: Is the 6203RS2 interchangeable with 6203-2RS or 6203DDU?
A: The 6203RS2 shares the same bore (17 mm) and outside diameter (40 mm) as 6203-2RS and 6203DDU but has single seals instead of double seals. All three are dimensionally compatible with standard manual pallet jack wheels. However, single-seal design provides less contamination protection in wet environments.

Q: What warranty or lifespan can be expected from a 6203RS2 bearing?
A: Typical bearing lifespan is 2 to 4 years in moderate warehouse use, depending on load, speed, and environment cleanliness. Single-seal design may reduce lifespan in wet or dusty conditions. Monitor for grinding noise, wheel wobble, or grease leakage as indicators that replacement is needed.
