Frequently Asked Questions
Q: What are the dimensions of the BS 6203 17MM 2RS bearing?
A: The BS 6203 17MM 2RS has an Outer Diameter of 1.574 inch (40MM), Inner Diameter of 0.669 inch (17MM), and Width of 0.472 inch (12MM). The 2RS designation indicates double rubber seals for moisture and contamination protection.
Q: What is the difference between 2RS and ZZ sealing on bearings?
A: The 2RS bearing features double rubber seals that provide superior moisture and liquid protection for wet environments, cold storage, and outdoor applications. ZZ bearings use metal shields offering lower friction but less sealing. The 2RS is preferred for manual pallet jacks operating in harsh conditions.
Q: Which equipment is the BS 6203 17MM 2RS bearing compatible with?
A: This bearing fits load wheel and drive assemblies on pallet jacks and material handling equipment from Crown, Toyota, Raymond, Yale, and other manufacturers requiring ISO 6203 series deep groove ball bearings with sealed construction.
Q: What maintenance does the BS 6203 17MM 2RS require?
A: The rubber seals are grease-filled and sealed, reducing relubrication requirements compared to open bearings. Inspect periodically for damage to the rubber seals. If seals are compromised or bearing exhibits noise or resistance, replacement is necessary. The sealed design extends intervals between maintenance.
Q: Can the BS 6203 17MM 2RS bearing be used in cold storage applications?
A: Yes. The double rubber seals protect against moisture condensation and ice buildup. The grease formulation in sealed 2RS bearings is specified for cold environments. However, verify the grease type is rated for your specific cold storage temperature range.
Q: What are the cross-reference part numbers for BS 6203 17MM 2RS?
A: This bearing conforms to ISO 6203 series standards and may be referenced as 6203-2RS, 6203-2RSH, or equivalent sealed deep groove ball bearings from other suppliers. Verify dimensions and seal type match before substitution.
