PEMCO
Frequently asked questions
Common questions about PEMCO from 3G Electric.
What wheel materials are available in the PEMCO caster line?
PEMCO casters supplied by 3G Electric include polyolefin, rubber, and polyurethane wheels. Polyolefin is a hard, durable material often used in light-duty applications such as carts and racks. Rubber treads are used where quiet operation and floor protection are needed, typically in light-duty swivel and rigid casters. Polyurethane wheels are common in medium-duty and heavy-duty casters, offering higher load capacity and resistance to abrasion. The specific material for each SKU is listed in the product specifications, along with wheel diameter, tread width, and bearing type.
How do I choose between a rigid and a swivel PEMCO caster?
Rigid casters are fixed in direction and are typically used in pairs with swivel casters to provide steering control while maintaining straight-line tracking. Swivel casters allow the equipment to turn and maneuver in tight spaces. In the PEMCO line, both rigid and swivel configurations are available across light-duty and medium-duty plate casters. For equipment that requires precise steering, a combination of two rigid and two swivel casters is common. If full maneuverability is needed, all four casters may be swivel type. Brake options such as side brake or total lock can be specified on swivel models to secure the equipment when stationary.
What is the difference between a side brake and a total lock on PEMCO casters?
A side brake locks the wheel to prevent rolling, but the swivel may still rotate. A total lock brake immobilizes both the wheel and the swivel, holding the equipment in a fixed position. PEMCO casters in the supplied range include side brake and total lock options. Total lock is often used on equipment that must remain stationary during loading or use, such as carts or workstations. Side brake is suitable when only rolling motion needs to be stopped. The brake type is indicated in the product specifications for each SKU.
What mounting styles are available for PEMCO plate casters?
PEMCO plate casters in the 3G Electric catalog use slotted rectangular mounting plates. This mounting style allows for some adjustment during installation and is common in light-duty and medium-duty applications. The mounting height, which is the distance from the floor to the top of the mounting plate, varies by wheel diameter and caster design. For example, medium-duty casters with 5-inch wheels have a mounting height of 6-1/2 inches, while those with 8-inch wheels have a mounting height of 9-1/2 inches. Matching the mounting height and plate dimensions to the equipment is necessary for proper fit and load distribution.
What are the load capacities of PEMCO casters?
Load capacity varies by caster series, wheel material, wheel diameter, and bearing type. The PEMCO casters supplied by 3G Electric are categorized as light-duty, medium-duty, and heavy-duty. Light-duty casters typically use polyolefin or rubber wheels with Delrin or ball bearings and are intended for carts, dollies, and light equipment. Medium-duty casters often use polyurethane wheels with ball bearings and are used on industrial carts, racks, and equipment. Heavy-duty casters are designed for higher loads. For specific load ratings, refer to the manufacturer's data for each part number. 3G Electric can assist with identifying the appropriate caster based on the application's load requirements.
Can 3G Electric help identify a replacement PEMCO caster if I don't have the part number?
Yes. If the manufacturer part number is not available, 3G Electric can help identify a compatible PEMCO caster using the existing caster's dimensions and features. Key information to provide includes wheel diameter, tread width, mounting height, mounting plate dimensions, caster type (swivel or rigid), wheel material, bearing type, and brake type. The catalog lists these attributes for each SKU, allowing cross-referencing. For best results, provide photos or measurements of the current caster. 3G Electric supports global shipping and can coordinate logistics for replacement orders.
