BEARING assembly (SINGLE SHIELD)
Frequently Asked Questions
Q: What is the difference between bearing assembly 220019676 and standard bearing assemblies?
A: Bearing assembly 220019676 features single shield protection, which means one side of the bearing has a metal shield while the other side is open. Single-shield bearings offer better grease retention and contamination protection compared to open bearings while allowing slightly easier inspection and maintenance access compared to double-shield designs. Single-shield bearings are commonly used in pallet jack load wheels and mast guide rollers.
Q: Which manual pallet jack models use bearing assembly 220019676?
A: Single-shield bearing assembly 220019676 is compatible with standard manual pallet jacks from manufacturers including Crown, Toyota, Raymond, and Yale. It is typically used in load wheel assemblies, mast rollers, and idler pulley applications. Confirm the bearing bore size, outer diameter, and width specifications match your equipment documentation before ordering.
Q: Does single-shield bearing 220019676 require periodic lubrication?
A: Single-shield bearings are typically pre-lubricated with grease and sealed to minimize contamination. Most do not require additional lubrication during normal service life in warehouse environments. However, in dusty or wet conditions, periodic inspection and occasional light regreasing may extend bearing life. Never over-grease, as excess grease generates heat and can damage the bearing.
Q: What is the expected lifespan of bearing assembly 220019676?
A: Single-shield bearings in manual pallet jack applications typically last 3 to 5 years under normal warehouse use. Load frequency, operator care, and floor conditions affect lifespan. Indicators of wear include increased noise, resistance during operation, or visible rust or scoring on the bearing race. More frequent or heavier use may reduce service life accordingly.
Q: Why choose single-shield over double-shield or open bearings for pallet jacks?
A: Single-shield bearings balance contamination protection with maintenance accessibility. The open side allows visual inspection for wear or contamination, while the shield side retains grease and keeps debris out. This design is ideal for warehouse and manufacturing environments where bearings need reliable performance without frequent teardown. Double-shield designs offer more protection but are harder to inspect; open bearings offer no protection.
