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 Hamilton Spinfinity S-ZFHS-6SPB is a breakthrough in the world of industrial casters. Its unique kingpinless design ensures an improved shock absorption, providing smoother rides and extending the lifespan of the caster. Unlike traditional casters, this maintenance-free model eliminates the need for regular upkeep, saving you both time and effort.
The caster features a 6-inch Ergo-Glide wheel with an 80A durometer rating. This balance between hardness and elasticity is the key to its versatility - the wheel is tough enough to resist wear and tear, but flexible enough to roll smoothly across a variety of surfaces. It also boasts 3/4" sealed precision ball bearings that not only improve rollability but also significantly reduce maintenance needs.
The S-ZFHS-6SPB model is a part of the trusted Hamilton Spinfinity series, known for high-performance casters that can withstand demanding applications. Each product in this line is recognized for its durable construction, capable of handling heavy-duty usage, and this model is no exception.
In addition to being reliable, the Hamilton Spinfinity S-ZFHS-6SPB Swivel Caster is designed with the user in mind. It offers easy swivel action for better maneuverability, especially in tight spaces. This feature, combined with its considerable load capacity, makes it an ideal choice for various industrial environments. Moreover, it is simple to install and operate, further emphasizing user-friendliness.
This caster runs a Cast Iron wheel. Steel / iron wheels give maximum capacity and durability on smooth, hard industrial floors and tolerate heat.
This caster uses a top-plate mount. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.
This is a Swivel caster. Swivel casters rotate 360 degrees for full maneuverability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
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 Cast Iron wheel performs best on smooth, hard industrial floors. 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.
