Frequently Asked Questions
Q: What are the exact dimensions and load capacity of the BS 6203 2RS-SS bearing?
A: This stainless steel deep groove ball bearing has a 17mm bore, 40mm outer diameter, and 12mm width. It is rated for 6.6-9.55 kN dynamic load capacity with a maximum rotational speed of 12,000 RPM. It carries ABEC-1 precision class (P0 tolerance) and features double rubber seals (2RS) on both sides for contamination protection.
Q: What equipment brands and applications does the BS 6203 2RS-SS fit?
A: This bearing is designed for marine, food processing, chemical processing, and high-moisture industrial environments. It is compatible with pallet jacks, lift equipment, and material handling machinery from Crown, Toyota, Raymond, Yale, Hyster, and similar manufacturers. The stainless steel construction makes it suitable for corrosion-prone environments where standard steel bearings fail quickly.
Q: What cross-reference part numbers does the BS 6203 2RS-SS replace?
A: This bearing replaces SS6203-2RS, S6203.2RSR, W203B (FAG), W6203-2RS1 (SKF), 6203-H-20T1XBDDU (NSK), 6203H-2RS (EZO), S6203-2RS, SS62032RS, and K222C. Verify that bore diameter and outer diameter match your equipment before ordering.
Q: What material is the BS 6203 2RS-SS constructed from?
A: This bearing is constructed entirely from corrosion-resistant stainless steel, including the races, balls, and cage. Stainless steel construction provides superior corrosion resistance compared to standard high carbon chromium steel and is essential for washdown environments, chemical exposure, and salt air applications.
Q: Does the BS 6203 2RS-SS come pre-lubricated?
A: Yes. This bearing comes with pre-applied food-grade grease lubrication, making it ready for immediate use in food processing and related applications. The double rubber seals retain the lubricant and keep out contamination. The bearing is not sealed for life and may require regreasing depending on operating conditions and speed.
Q: How does the ABEC-1 precision class affect bearing performance and lifespan?
A: ABEC-1 (P0 tolerance class) is a general-purpose precision grade suitable for most material handling and pallet jack applications. It offers good dimensional tolerances and rotational accuracy at lower cost than higher precision grades. This grade is appropriate for speeds up to 12,000 RPM and provides reliable service life in normal industrial conditions.
