Frequently Asked Questions
Q: What are the exact dimensions and load rating of the BS 6204 2RS-SS bearing?
A: The BS 6204 2RS-SS is a stainless steel deep groove ball bearing with a 20 mm bore, 47 mm outside diameter, and 14 mm width. It is rated for dynamic loads up to 2220 lbs and is suitable for high radial loads with light axial direction loads.
Q: Is this bearing compatible with other stainless steel bearing brands?
A: Yes, the BS 6204 2RS-SS is interchangeable with SKF, KOYO, FAG, and NSK stainless steel 6204 equivalents. Cross-reference part numbers include 6204, 6204-Z, 6204-ZZ, 6204-RS, 6204-2RS, and 6204-NR variants depending on shield or seal configuration.
Q: What is the seal type and does it provide protection in wet environments?
A: This bearing features 2RS NBR contact lip seals on both sides. The 2RS designation means two rubber contact seals that provide enhanced protection against contamination and moisture, making it suitable for wet floor and outdoor material handling applications.
Q: What tolerance grade does this bearing meet and is it pre-lubricated?
A: The BS 6204 2RS-SS meets ABEC 1 precision tolerance and is DIN 625-1 compliant. It is lifetime greased at the factory, meaning no initial lubrication is required before installation on your equipment.
Q: What material is this bearing made from and what is its typical service life?
A: This bearing is constructed from stainless steel, which provides superior corrosion resistance compared to standard chrome steel bearings. Stainless steel bearings typically deliver longer service life in corrosive environments such as food processing, washdown areas, or refrigerated equipment.
