    Sugatsune Swivel Caster 5-1/2" No Brake, Threaded Stem Mount 264lb Capacity - MX-125N16

    Description

    Sugatsune Swivel Caster For Smooth Controlled Moves

    Sugatsune Swivel Caster 5-1/2 No Brake describes a caster from Sugatsune America that uses a threaded stem mount and fits the stem mounted casters category, so it suits equipment and furniture already set up for a threaded stem connection. The caster is identified as type swivel, which allows the wheel to rotate around a vertical axis, so carts and fixtures turn in tight spaces instead of dragging. The wheel diameter is specified as 5-17/32 inches, so it rolls more easily over small floor transitions than smaller casters in the same class. The wheel material is nylon/polyurethane, which combines a hard-running core with a softer tread for a balance of roll and grip on typical shop and facility floors. The load capacity is listed as 264 lb, so each caster can support that load rating when laid out in a properly designed base. The product is described as RoHS compliant, so it aligns with restrictions on certain hazardous substances where that matters.

    Key Caster Details That Support Daily Use

    • The mounting type is stem, defined in the product class as threaded stem mount, so the caster threads into a prepared socket or nut, giving a positive mechanical connection that suits fixtures designed around stem-mounted casters.
    • The caster type is swivel, so the wheel can rotate around a vertical axis, allowing equipment to change direction with minimal effort on job floors and in shop aisles where turning room is limited.
    • The wheel diameter of 5-17/32 inches increases rolling circumference, so carts sit a bit higher and can move more steadily over joints, thresholds, or minor floor irregularities found in warehouses and workrooms.
    • The nylon/polyurethane wheel material combines a nylon base with a polyurethane running surface, so the wheel can roll smoothly while maintaining traction on many hard flooring surfaces seen in woodworking and fabrication environments.
    • The stated load capacity of 264 lb defines the working rating of a single caster, so designers and installers can calculate how many casters are required to support the total expected load on a platform or cabinet.

    Threaded Stem Swivel Mounting And Setup

    The mounting type is stem within a threaded stem mount product class, so installation centers on matching the caster stem threads to a corresponding threaded insert, nut, or frame connection on the equipment. This approach allows installers to spin the caster into position rather than aligning top plates, which can speed change-outs on fixtures already drilled and tapped for a specific stem size. Because the caster is defined as swivel type, the mounted wheel can pivot freely once threaded into place, so operators can reposition heavy fixtures without lifting or shuffling. The 5-17/32 inch wheel diameter also affects install height, so builders can plan finished working heights or clearance under cabinets and carts around that dimension when selecting locations for the threaded stems.

    How This MX-125N16 Caster Works In Practice

    Where This Threaded Stem Caster Is Applied

    The MX-125N16 swivel caster sits in the stem mounted casters category with a threaded stem mount product class, so it aligns with carts, racks, and frames that accept stem-mounted wheels rather than plate mounts. The 5-17/32 inch wheel diameter positions this caster for applications where slightly larger rolling diameter is useful, such as moving work carts across expansion joints or doorway transitions. Because the caster type is defined as swivel, it supports use on fixtures that need to be steered around obstacles or rotated in place, like shop trolleys or mobile cabinets. The nylon/polyurethane wheel material suits indoor surfaces common to woodworking and industrial shops, where a firm-running wheel with a polyurethane tread is often selected for consistent rolling behavior.

    Details That Support Movement And Load Handling

    The web description notes a caster with clean appearance, so it can be used on visible fixtures where hardware aesthetics matter along with movement. The same description specifies a dual brake system that can be locked on swivel only or wheel and swivel in one step, so operators can either hold the steering direction or fully immobilize the wheel to stabilize a cart during work. A large lock lever is identified for the swivel and a small lock lever for the wheel, which separates functions so users can quickly choose how much motion to restrict. The caster is described as easy operation, so the brake design is arranged for straightforward engagement and release in routine use. The text states that it works as rigid type when swivel locked for easy movability, so locking the swivel converts steering behavior to a straight-line track, helping carts roll predictably along aisles. Together with the 264 lb load capacity, these functional details allow planners to balance maneuverability and holding control while sizing casters to expected weights.

    Common Questions About This Sugatsune Stem Caster

    What type of mounting does the MX-125N16 caster use?

    The MX-125N16 caster uses a threaded stem mount, so it installs into threaded sockets or nuts on compatible equipment and fits layouts designed for stem mounted casters.

    How does the dual brake system on this caster function?

    The caster has a dual brake system that can lock swivel only or both wheel and swivel in one step, so users can either hold direction or fully stabilize the caster.

    What do the large and small lock levers control?

    The large lock lever controls the swivel and the small lock lever controls the wheel, so operators can independently manage steering lock and wheel rotation.

    How does swivel lock affect how the caster rolls?

    When the swivel is locked, the caster works as a rigid type, so carts track in a straight line for easier movement down aisles or along benches.

    What load can each MX-125N16 swivel caster handle?

    Each MX-125N16 swivel caster has a 264 lb load capacity, so total cart or fixture rating depends on how many casters support the structure.

    Why is the wheel material listed as nylon and polyurethane?

    The wheel uses nylon and polyurethane, so it combines a firm-running core with a polyurethane tread that supports controlled rolling on typical hard shop floors.

    Select This Caster For Controlled Mobile Fixtures

    This Sugatsune America MX-125N16 threaded stem swivel caster combines a 5-17/32 inch nylon/polyurethane wheel, dual brake system, and 264 lb capacity, so it supports shop and facility carts that need controlled steering, straight-line travel, and dependable rolling behavior. The clean appearance suits visible fixtures, while the separate large swivel lever and small wheel lever simplify locking choices during daily use. For projects built around stem mounted casters, this configuration provides a defined load rating and practical movement control for cabinets, racks, and work trolleys using threaded stem mounting points.
