Frequently asked questions
Common questions about SHEPHERD CASTER from 3G Electric.
What stem types are available in Shepherd Caster stem casters?
Shepherd Caster stem casters are offered with threaded stems and grip-neck stems. Threaded stems, such as 1/2"-13, provide a secure threaded connection for equipment with matching receptacles. Grip-neck stems are designed for tubular legs and are retained by a friction ring or grip ring, allowing for easy installation and removal. Both types are available in swivel and swivel-with-brake configurations. The choice depends on the mounting interface of the equipment and whether height adjustment or quick change is needed. 3G Electric stocks multiple SKUs covering both stem types in various wheel diameters.
What wheel materials does Shepherd Caster use in its casters?
Shepherd Caster casters feature wheels made from rubber, polyurethane, and other polymer compounds. Rubber wheels are used for floor protection and noise reduction, making them suitable for furniture and office equipment. Polyurethane wheels offer higher load capacity and resistance to oils and chemicals, often used in industrial and food service applications. Some models have clear or gray tread colors. The wheel material affects rolling resistance, floor marking, and load rating. 3G Electric's catalog includes casters with rubber, polyurethane, and other tread materials to match specific application requirements.
Are Shepherd Caster products NSF-listed for sanitary applications?
Yes, many Shepherd Caster models are NSF-listed, meaning they meet the National Sanitation Foundation's standards for equipment used in food handling and healthcare environments. NSF listing indicates that the caster is designed for easy cleaning and corrosion resistance. These casters are commonly used on food service carts, medical equipment, and shelving. When specifying for sanitary applications, verify the specific SKU's NSF status. 3G Electric supplies NSF-listed Shepherd Caster products among its 32 SKUs, supporting compliance with hygiene regulations.
What is the load capacity range for Shepherd Caster stem casters?
Shepherd Caster stem casters are generally designed for light- to medium-duty applications. Load capacities vary by model and wheel size, typically ranging from around 100 pounds to several hundred pounds per caster. Factors affecting capacity include wheel diameter, tread material, bearing type, and mounting method. For precise load ratings, consult the individual product specifications. 3G Electric provides detailed specs for each SKU, including wheel diameter, width, and mounting height, to assist in selecting the appropriate caster for the intended load.
Can Shepherd Caster casters be used on uneven floors?
Shepherd Caster casters with swivel mechanisms are designed to navigate minor floor irregularities. Larger wheel diameters, such as 3 inches or 3 7/8 inches, roll more easily over cracks and transitions than smaller wheels. However, for highly uneven surfaces, a caster with a larger wheel and softer tread may be required. Braked models can lock the wheel to prevent movement on slopes. 3G Electric stocks various wheel sizes and tread materials to accommodate different floor conditions. Always consider the operating environment when selecting casters.
What is the difference between Shepherd Caster grip-neck and threaded stem casters?
Grip-neck stem casters have a stem with a grooved or ringed design that fits into a tubular leg and is held in place by a grip ring or friction. They are typically used on furniture and equipment with round tubular legs. Threaded stem casters have a threaded post that screws into a threaded socket or nut, providing a more secure and adjustable connection. Threaded stems are common on office equipment and carts where a firm attachment is needed. Both types are available in swivel and braked versions. 3G Electric carries both grip-neck and threaded stem casters from Shepherd Caster.
