Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang SHEPHERD CASTER dari 3G Electric.
What does NSF listing mean for Shepherd Caster sanitary casters?
NSF listing indicates that the caster has been tested and certified by NSF International to meet specific standards for sanitation and cleanability. For Shepherd Caster models such as the PRE50748ZN-3R and PRQ30124ZN-3H, this means the materials and design resist bacterial growth, withstand frequent washdowns with detergents and sanitizers, and do not harbor contaminants. This is relevant for food processing, pharmaceutical, and healthcare environments where hygiene is critical.
What is the difference between swivel and rigid Shepherd Caster plate casters?
Swivel casters have a rotating yoke that allows the wheel to pivot 360 degrees, enabling easy directional changes. Rigid casters have a fixed yoke that keeps the wheel aligned in one direction, providing straight-line tracking. Shepherd Caster offers both types in their plate caster line, such as the rigid PRQ30124ZN-3H and swivel models. Selection depends on whether the application requires maneuverability or stability.
What wheel materials are available for Shepherd Caster stem casters?
Shepherd Caster stem casters are available with rubber, polyurethane, and steel wheels. Rubber wheels (e.g., black on PRE50748ZN-3R) provide cushioning and floor protection. Polyurethane wheels (e.g., gray on PRE20302ZN-TPU) offer higher load capacity and abrasion resistance. Steel wheels (e.g., clear on PRE20302ZN-VPR01(CG)) are used for heavy loads on smooth surfaces. The choice depends on floor type, load, and environmental conditions.
How do I determine the correct mounting height for a Shepherd Caster stem caster?
Mounting height is the distance from the bottom of the wheel to the top of the mounting plate or stem. For Shepherd Caster models like the PRE50748ZN-3R, the mounting height is 5 3/4 inches. To select the correct height, measure the existing caster or the clearance required for your equipment. Ensure the total height allows for proper load distribution and clearance under the cart or fixture.
What thread sizes are available for Shepherd Caster threaded stem casters?
Shepherd Caster threaded stem casters are available in various thread sizes, such as 1/2"-13 as seen in model PRE50748ZN-3R. Other common sizes include 3/8"-16 and 5/16"-18, depending on the model. The thread size must match the mating hole or nut on the equipment. Check the manufacturer part number or specifications to confirm compatibility.
