Frequently Asked Questions
Q: What are the core specifications of the BS 6203 17MM ZZ bearing?
A: The BS 6203 17MM ZZ is an ISO 6203 series deep groove ball bearing with a 17MM bore diameter. The ZZ designation indicates metal shields on both sides. This bearing fits various pallet jack load wheel and drive assemblies across major equipment manufacturers.
Q: How do metal shields compare to rubber seals for bearing protection?
A: Metal shields (ZZ) reduce friction and operating temperature compared to rubber seals (2RS), allowing higher rotational speeds. However, they provide less protection against moisture and contaminants. Metal shields are suitable for dry, indoor material handling; rubber seals perform better in wet or cold storage environments.
Q: What equipment types is the BS 6203 17MM ZZ compatible with?
A: The BS 6203 17MM ZZ is compatible with pallet jacks, load wheel assemblies, and drive mechanisms from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT that require ISO 6203 series specifications with 17MM bore.
Q: Is the BS 6203 17MM ZZ suitable for outdoor or wet environments?
A: The metal shields offer basic dust protection but limited moisture resistance. For wet, outdoor, cold storage, or washdown applications, a 2RS sealed bearing variant is recommended. The BS 6203 17MM ZZ is best suited for climate-controlled indoor material handling operations.
Q: What is the relationship between bore diameter and pallet jack load wheel fitment?
A: The 17MM bore accommodates the axle shaft diameter in load wheel hubs. Verify your equipment shaft diameter matches 17MM before ordering. Mismatched bore sizes cause improper fitment, poor load distribution, and premature failure. Consult your equipment manual for shaft specifications.
Q: How do I confirm the BS 6203 17MM ZZ is correct for my pallet jack?
A: Measure the existing bearing bore diameter (should be 17MM), outer diameter (40MM is standard for 6203 series), and width. Cross-reference your pallet jack model and current bearing part number against ISO 6203 specifications. Verify mounting press-fit tolerance compatibility.
