Frequently Asked Questions
Q: What are the dimensional specifications of the PL X-4608-SC bearing?
A: The PL X-4608-SC is a double-sealed deep groove ball bearing with a 20 mm bore, 47 mm outer diameter, and 14 mm width. These dimensions are precision-engineered to fit commercial material handling equipment wheel assemblies in manual pallet jacks.
Q: What materials are used in the PL X-4608-SC bearing construction?
A: The PL X-4608-SC features high-carbon chromium steel conforming to ASTM A295 for the bearing rings. The ball material also meets high-carbon chromium steel standards, providing superior hardness and wear resistance necessary for load-bearing applications in material handling equipment.
Q: What cross-reference part numbers match the PL X-4608-SC?
A: The PL X-4608-SC cross-references to EX-4608-SC and X-4608. Equivalent part numbers include PLX-4608-SC and PLX-4608-BULK. This bearing supersedes EX-4607SC in current applications. Always verify dimensional specifications match your equipment before ordering a replacement.
Q: What is the significance of the double-sealed design in the PL X-4608-SC?
A: The double-sealed design (SC suffix) provides protection from contamination and moisture ingress in wet or dirty warehouse environments. The seals extend bearing life by preventing grease degradation and protecting bearing surfaces from corrosive exposure.
Q: What is the typical lifespan of the PL X-4608-SC bearing?
A: Bearing lifespan depends on load profile, maintenance frequency, and operating environment. Under normal warehouse conditions with regular load cycling, the PL X-4608-SC provides extended service life. If the bearing exhibits noise, grinding, or loose wheel movement, replacement is necessary to maintain equipment safety.
