This listing is for a high-quality Total Locking Swivel Stem Caster. The stem is 1/2"-13 x 1-1/2" meaning the diameter of the stem is 1/2" and 1.5 inches in length. The Steel Swivel Yoke that holds the wheel is Lacquer Dipped which prevents rust and corrosion and the steel is Hardened Steel which adds strength and durability to the frame of the Caster allowing it to handle more use and abuse while giving this caster a much longer lifespan compared to other Caster brands on the market. We also provide seals in the raceway which are known as raceway seals as an added benefit. Raceway seals prevent dust, hair, and other debris from accumulating in the bearings of the raceway allowing a smoother swiveling motion and a much longer lifespan. We provide lock nuts on every order so you don't need to go to the hardware store and buy locking nuts. The Brake on this Caster is known as a Total Locking Brake which locks the Swivel Raceway from Turning and the Wheel from rolling at the same time. The Brake pedal is red in color and very easy to engage and disengage. The Polyurethane Wheels we provide have a bright red tread on a gray center. We add dual precision bearings in the middle of the wheel for a smooth and quiet ride, most other brands only have a single precision bearing in the middle of the wheel. Dual (2) Precision Bearings are a huge upgrade compared to most wheels that have a plain bore or a single bearing. Dual Precision Bearings are much higher quality, allow easier initiation and roll-ability as well a smoother and quieter ride. We also provide full dust covers/dust caps on the outside of the dual precision bearings which sit in the center of the wheel on both sides. Dust covers prevent hair and other debris from building up in the bearings which also adds a much longer lifespan to this caster. Overall, this is the best 4" x 1-1/4" Total Locking Caster on the Market hands down. If you are looking for a high-quality total locking stem caster, this is the one you want.

This 4" x 1-1/4" Polyurethane Total Lock Caster – 300 lb is rated to 300 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.
This caster runs a Polyurethane wheel with a 1-1/4" tread width. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.
This caster uses a Threaded Stem mount (1/2"-13 x 1-1/2" stem). Stem casters press or thread into a socket - verify the stem diameter and length match your existing setup before ordering.
This is a Swivel with Total Lock Brake caster with a wheel brake. Swivel casters rotate 360 degrees for full maneuverability. The brake locks the wheel to hold the load in place. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
Rated for -30°F to 140°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).
The Polyurethane wheel performs best on smooth to semi-smooth floors including sealed concrete, tile, and epoxy. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 6-3/16". Account for it when checking equipment clearance, dock height, and ergonomic working height.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
