All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.

The 5/16" diameter by 1-1/2" long Maxim Hex Nut Glides are commonly known as Easy-Adjust Leveling Mounts with Threaded Studs. Our Easy Adjustable Threaded Glides are effortless to adjust and level your appliances, equipment, chairs, or whatever you wish to install these glides on due to having the hex nut on the base of the stem. The Glide base is made of a heavy-duty and durable polyurethane material that will allow you to protect your flooring while still allowing the user to maneuver and adjust with ease. Leveling your equipment is as easy as turning the hex nut, either way, extending or retracting to have a perfect level anywhere. If you don't see the exact stem dimensions or base diameters for the glide you are looking for, please reach out to us, as we only list our most popular items, although we have many other sizes available and in stock.

This caster runs a Polyurethane wheel with a 1-1/2" tread width. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.
This caster uses a Threaded Stem mount (5/16"-18 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.
Rated for -20°F to 180°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.
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).
