Frequently Asked Questions
Q: What are the dimensions and specifications of the BS 1621 2RS bearing?
A: The BS 1621 2RS is a deep groove radial ball bearing with a 1/2 inch (12.7 millimeter) bore, 1-3/8 inch (34.925 millimeter) outer diameter, and 7/16 inch (11.1 millimeter) width. The bearing is double sealed with nitrile rubber, pre-lubricated, and manufactured from chrome steel (AISI 52100). These dimensions make it suitable for medium-duty manual pallet jack applications.
Q: What does the 2RS designation mean on the BS 1621 2RS bearing?
A: The 2RS designation means the bearing has two rubber seals (one on each side). These seals provide protection against dust, dirt, and moisture ingress while retaining the factory pre-lubrication. The 2RS configuration makes this bearing suitable for wet environments and outdoor material-handling duty. The seals reduce risk of premature bearing failure due to contamination.
Q: What manual pallet jack models does the BS 1621 2RS bearing fit?
A: The BS 1621 2RS bearing is designed for manual pallet jack load wheels and steer wheels from Crown, Toyota, Raymond, Yale, and other OEM brands that use 1/2 inch bore load wheel configurations. The bearing fits medium-duty pallet jacks rated for 2700 to 4000 pounds. Verify your pallet jack bearing bore size and wheel diameter before ordering to confirm compatibility.
Q: How long does the BS 1621 2RS bearing remain pre-lubricated?
A: The factory pre-lubrication on the BS 1621 2RS bearing typically remains effective for 12 to 24 months of normal duty cycle on a manual pallet jack. The double rubber seals help retain grease but cannot prevent all lubrication migration over time. Inspect for smooth, quiet rotation regularly. If bearing movement becomes rough or noisy after 18 to 24 months, replacement is recommended rather than attempting to regrease the sealed bearing.
Q: Can the BS 1621 2RS bearing be used in an electric forklift or only manual pallet jacks?
A: The BS 1621 2RS is engineered for medium-duty manual pallet jack applications. While the bore size and dimensions may physically fit some light-duty electric forklifts, the bearing load rating may be insufficient for forklift duty cycles. Forklift applications require verification of dynamic load ratings and speed limits. Use this bearing only in manual pallet jacks unless load analysis confirms it is rated for your specific forklift model.
