- Axle: A central shaft for rotating wheels or gears.
- Axel Bolt: A type of bolt specifically designed to secure an axle in place.
- Bearings: Machine elements that allow one part to bear (i.e., to support and to move freely relative to) another, often reducing friction between moving parts.
- Bolt Hole Spacing: The distance between the centers of bolt holes, is often used to determine the compatibility of components like mounting plates.
- Bore: The inner diameter of a bearing or the hollow part inside any cylindrical object.
- Caster Size: Refers to the overall diameter of the caster wheel.
- Durability: The ability of a component to withstand wear, pressure, or damage.
- Ergonomic: Designed for efficiency and comfort in the working environment.
- Fastening Type: The method or design used to securely attach or join objects together.
- Hot Forged: A manufacturing process involving the shaping of metal using localized compressive forces at high temperatures.
- Keyway: A slot shaped to fit a key, ensuring components are aligned correctly when assembled.
- Kingpin: A central pin in a steering mechanism, around which a vehicle’s steerable wheels pivot.
- Kingpinless: A type of caster design that eliminates the traditional kingpin to improve durability and load capacity.
- Load Capacity: The maximum weight that a component, such as a caster, can safely support.
- Locknut: A nut designed to resist loosening under vibrations and torque.
- Mounting Bolt: A bolt used to secure a caster to a device or piece of equipment.
- Mounting Plate: A flat piece of metal with holes for bolts, used to attach casters to objects.
- NSF: National Sanitation Foundation, an organization that sets health and safety standards for products and systems.
- OEM: Original Equipment Manufacturer, indicating a component made specifically for a particular product.
- Offset: The distance between the centerline of the wheel and the vertical line through the center of the shaft or axle.
- Overall Height: The total height of a caster, including the wheel and mounting device.
- Plain Bore: A simple cylindrical bore without any bearings.
- Pneumatic: Relating to or using gas (usually air) under pressure to move or work.
- Raceway: The tracks in which balls or rollers in a bearing travel.
- Rigid: Refers to casters that do not swivel; they are fixed in one direction.
- Seals: Components used to prevent the passage of fluids, dust, or other materials through a bearing or part.
- Shock Load: A sudden and extreme load or force applied to a component.
- Static Load: The maximum load that can be applied to a component without movement.
- Swivel Radius: The radius around which a swivel caster can pivot or turn.
- Temperature Range: The range of temperatures within which a component can operate effectively.
- Total Locking: A caster feature that locks both the wheel and the swivel mechanism, preventing any movement.
- Tread Width: The width of the wheel’s part that makes contact with the ground.
- Wheel Durometer: A measure of the hardness of a caster wheel, affecting its rollability and how much noise it makes.
