Frequently Asked Questions
Q: What are the specifications for the BS 6203 2RS bearing?
A: The BS 6203 2RS is an ISO 6203 series deep groove ball bearing with Outer Diameter 1.574 inch (40MM), Inner Diameter 0.750 inch (19.05MM), and Width 0.472 inch (12MM). The 2RS indicates double rubber seals for contamination and moisture protection.
Q: What is the bore diameter difference between BS 6203 17MM and BS 6203 2RS?
A: The BS 6203 17MM has a 17MM bore (0.669 inch), while the BS 6203 2RS has a 19.05MM bore (0.750 inch). This difference affects shaft compatibility and load wheel hub design. These are not interchangeable; verify your equipment axle shaft diameter before selecting.
Q: Which pallet jack brands use the BS 6203 2RS bearing?
A: The BS 6203 2RS with 19.05MM bore fits load wheel and drive assemblies on equipment from Crown, Toyota, Raymond, Yale, Hyster, and other material handling manufacturers that require ISO 6203 series specifications with sealed construction and this specific bore size.
Q: Why is the 2RS seal important for manual pallet jacks?
A: Double rubber seals protect the bearing from water, dirt, and salt spray common in warehouse, dock, and outdoor operations. Sealed bearings maintain lubrication effectiveness and reduce wear rates compared to open bearings. The 2RS design extends bearing life in contaminated environments.
Q: What is the relationship between bearing width and load wheel performance?
A: The 0.472 inch (12MM) width determines load distribution across the rolling elements. Wider bearings support higher radial loads and distribute stress more evenly. This width is standard for 6203 series bearings. Do not substitute with narrower bearings without verifying equipment load rating compatibility.
Q: What is the 19.05MM bore shaft compatibility for BS 6203 2RS?
A: The 0.750 inch (19.05MM) bore accommodates axle shafts of approximately 19MM diameter. Verify your equipment shaft diameter matches exactly. Oversized or undersized shafts result in press-fit misalignment, poor bearing performance, and accelerated wear. Consult your pallet jack manual for precise shaft specifications.
