Frequently Asked Questions
Q: What is a single-shield bearing?
A: A single-shield bearing has a protective metal or plastic cover on one side of the bearing races. This design shields bearings from dust and debris while allowing some drainage, making it suitable for wet or outdoor environments.
Q: What pallet jack applications use the 311000-019 bearing?
A: The 311000-019 is designed for manual and electric pallet jack load wheels, caster assemblies, and drive wheel applications. Verify your equipment bearing pocket dimensions and bore size before ordering.
Q: Why choose a single-shield design over sealed or open bearings?
A: Single-shield bearings offer a middle ground: they prevent gross contamination while allowing moisture and debris to drain out. This is ideal for material handling equipment used in cool storage, damp warehouses, or outdoor dock areas.
Q: How does shield design affect bearing replacement intervals?
A: Single-shield bearings typically require more frequent inspection and possible replacement than sealed bearings in harsh environments. In normal warehouse conditions, they perform reliably for extended periods without maintenance.
