Product Description
BS 6203 3/4 Inch Deep Groove Ball Bearing with Double Rubber Seals
This sealed bearing assembly features a 3/4-inch (19.05mm) inner diameter bore with precision outer dimensions of 40mm OD and 12mm width, meeting standard 6203 bearing series specifications. The double rubber seal (2RS) design provides effective contamination protection in dusty and wet warehouse environments typical of material handling equipment.
Engineered for compatibility with pallet jacks and lift trucks from major manufacturers including Crown, Toyota, Raymond, Yale, and Hyster. The 2RS sealed construction requires no external lubrication and offers reliable performance across thousands of duty cycles in demanding dock and warehouse applications.
Frequently Asked Questions
Q: What is the bore size of the BS 6203 3/4 2RS bearing?
A: The BS 6203 3/4 2RS has a 3/4-inch (0.75-inch or 19.05mm) inner diameter bore. This metric-to-imperial size conversion is commonly found on equipment manufactured for mixed unit markets, particularly in North America and some Asian markets.
Q: Is the BS 6203 3/4 2RS compatible with standard 6203 bearing applications?
A: No. The standard 6203 bearing uses a 17mm bore, while the BS 6203 3/4 2RS uses a 3/4-inch (19.05mm) bore. These are not interchangeable. Verify your equipment shaft diameter before ordering. Installing a bearing with an incorrect bore size will cause premature failure or unsafe operating conditions.
Q: What does the 2RS designation mean on this bearing?
A: The 2RS designation means double rubber seals, one on each side of the bearing. These seals provide contamination protection in dusty or wet industrial environments. The seals are contact-type and can slow rotational speed slightly compared to non-sealed bearings, but provide superior protection for material handling equipment.
Q: Which pallet jack brands use the 3/4-inch bore bearing size?
A: The 3/4-inch bore is common on equipment from Crown, Toyota, Raymond, and certain older models from Yale and Hyster, particularly those manufactured for North American markets. Always confirm bearing dimensions against your equipment specifications before ordering, as bore size is not interchangeable across equipment models.
Q: What is the outer diameter and width of the BS 6203 3/4 2RS?
A: The outer diameter is 40mm and the width is 12mm. These dimensions follow the metric standard for the 6203 bearing series. Combined with the 3/4-inch bore, these dimensions are unique to specific equipment models.
