Frequently Asked Questions
Q: What are the specifications of the BS Q34-2PC bearing?
A: The BS Q34-2PC is a sealed deep groove ball bearing with a 20 mm bore, 47 mm outer diameter, and 14 mm width. It features 2RS rubber contact seals on both sides and is pre-lubricated for extended service life.
Q: What equipment does the BS Q34-2PC fit?
A: The BS Q34-2PC is used in manual pallet jack wheel assemblies and industrial material handling equipment from manufacturers like Crown, Toyota, Raymond, and Yale. Verify bore diameter matches your wheel hub before ordering.
Q: What does the 2RS seal designation mean?
A: The 2RS designation indicates rubber contact seals on both sides of the bearing. These seals keep contaminants and moisture out while retaining grease inside, making the bearing suitable for wet storage and outdoor pallet jack operations.
Q: What materials are used in the BS Q34-2PC bearing?
A: The races and balls are constructed from high carbon chrome steel (SAE 52100) for hardness and wear resistance. The seal material is nitrile rubber, which tolerates moisture and temperature variation in material handling environments.
Q: Is the BS Q34-2PC pre-lubricated, and how long does it last?
A: Yes, the BS Q34-2PC arrives pre-lubricated with grease and sealed. Service life is typically 1,000 to 3,000 operating hours in normal pallet jack wheel applications. Replace the bearing if you detect noise, rough rotation, or lateral play in the wheel.
