Frequently Asked Questions
Q: What are the dimensions and material specifications of the BS 6303 2RS-SS bearing?
A: The BS 6303 2RS-SS is a stainless steel deep groove ball bearing with an outer diameter of 1.850 inch (47MM), inner diameter of 0.669 inch (17MM), and width of 0.551 inch (14MM). The 2RS designation indicates it has rubber seals on both sides for protection against contamination. The stainless steel construction resists corrosion and rust in wet environments and cold storage applications.
Q: What equipment types does the BS 6303 2RS-SS bearing fit?
A: This bearing fits load wheel assemblies on electric and manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. The stainless steel material makes it ideal for wet environments, marine applications, and cold storage equipment where corrosion resistance is critical. Verify your equipment model and dimensional specifications before ordering.
Q: Why choose stainless steel over standard steel for this bearing?
A: Stainless steel bearings resist rust and corrosion significantly better than carbon steel, especially in humid, wet, or salt-exposed environments. The BS 6303 2RS-SS maintains structural integrity and smooth operation longer in corrosive conditions. This makes it necessary for material handling equipment used in freezers, wet manufacturing floors, coastal facilities, or washdown environments where standard steel bearings would degrade rapidly.
Q: What is the difference between 2RS and ZZ bearing seals?
A: 2RS means the bearing has rubber or elastomer seals on both sides that contact the inner race, providing better contamination protection and higher operating temperatures. ZZ indicates metal shields on both sides that do not contact the inner race, allowing easier lubrication access but providing less protection. For wet or dirty environments, 2RS seals are superior.
Q: How long does the BS 6303 2RS-SS bearing last in normal operation?
A: Under typical material handling duty, a stainless steel 2RS bearing can run 2,000-4,000 operating hours before replacement becomes necessary. Lifespan depends on load, speed, and contamination exposure. The sealed design extends life by reducing water and particulate ingress. In wet storage or high-humidity environments, stainless steel maintains reliability far longer than carbon steel bearings, which may fail within 500-1,000 hours due to corrosion.
