BS 6304 2RS

Frequently Asked Questions

Q: What are the dimensions of the BS 6304 2RS bearing?
A: The BS 6304 2RS is a deep groove ball bearing with outer diameter of 2.047 inch (52MM), inner diameter of 0.787 inch (20MM), and width of 0.591 inch (15MM). The 2RS designation indicates rubber seals on both sides for contamination protection.

Q: What equipment does the BS 6304 2RS fit?
A: The BS 6304 2RS fits load wheel and drive wheel assemblies on electric and manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. This larger bearing than BS 6303 is used in higher-load applications. Always verify model and serial range compatibility before ordering.

Q: Is the BS 6304 2RS suitable for wet storage or freezer environments?
A: The BS 6304 2RS is carbon steel with rubber seals, making it suitable for damp indoor environments but not ideal for prolonged wet or cold storage. The seals provide better protection than shields but carbon steel will still corrode in wet conditions. For freezer or high-humidity applications, order the BS 6304 2RS-SS variant with stainless steel construction instead.

Q: How does the BS 6304 2RS compare to the BS 6303 ZZ in load capacity?
A: The BS 6304 2RS is larger (52MM OD versus 47MM OD) and has higher dynamic and static load ratings than the BS 6303 ZZ. Use the BS 6304 2RS for pallet jacks with heavier maximum capacity ratings or rough-duty applications. Consult your equipment specifications to determine which bearing model is required for your application.

Q: What is the expected service life of the BS 6304 2RS bearing?
A: Under typical warehouse duty with regular maintenance, the BS 6304 2RS operates for 2,500-4,000 hours before replacement is recommended. Sealed 2RS design extends life compared to shielded bearings by reducing contamination. Inspect annually for noise, play, or resistance. Replace immediately if the bearing exhibits grinding sounds or binding.
