3.5-Inch vs 1.5-Inch Stainless Conveyor Rollers: Choose the Right Size

Choose the FIPUX 3.5-inch roller for its larger stated roller and shaft dimensions, or select the 1.5-inch galvanized-end roller when that smaller format and lower listed price fit the job.

Last updated Aug 17, 2026

Choosing a conveyor roller for conveyors, loading docks, or racking comes down to physical dimensions before anything else. These two single stainless steel rollers share silver coloring and galvanized end caps, but their stated roller and shaft measurements point to substantially different conveyor setups.

Quick verdict

Choose the FIPUX 3.5-Inch Stainless Steel Gravity Conveyor Roller when your requirement centers on a 3.5-inch roller diameter and a 20 mm shaft. Choose the Galvanized End 1.5-Inch Stainless Steel Conveyor Roller when a 1.5-inch roller diameter and 12 mm shaft are the target dimensions. The listed-price gap is USD 19.48, with the 1.5-inch roller at the lower end of the pair.

Where each roller stands out

FIPUX 3.5-Inch Stainless Steel Gravity Conveyor Roller is the larger-format choice. Its 3.5-inch roller diameter is more than double the 1.5-inch measurement of the other option, and it also has the larger stated shaft. Built-in bearings and a spring press-in installation method are part of its described configuration. This is the direction to take when those larger component measurements are the deciding requirement.

Galvanized End 1.5-Inch Stainless Steel Conveyor Roller stands out on listed price and its smaller stated format. At USD 34.21, it is the lower-priced choice, while retaining the same stainless steel surface and galvanized-end-cap construction described for the FIPUX roller. It is a sensible match when the conveyor layout is designed around the 1.5-inch roller and 12 mm shaft dimensions.

Product notes

FIPUX 3.5-Inch Stainless Steel Gravity Conveyor Roller

1Pack Stainless Steel Gravity Conveyor Roller WAREHOUSES 3.5" Dia 16" L Silver

The FIPUX roller is the clear choice when the job calls for the larger roller and shaft measurements in this comparison. Its stainless steel surface, galvanized end caps, built-in bearings, and spring press-in installation method make its component configuration more specific than a basic roller description. The roller is also described for assembly lines, warehouses, and manufacturing facilities, where gravity rollers are used to transport goods. Its practical limitation is the higher listed price in this head-to-head, so the larger format should be central to the decision. The FIPUX option is sold as a single silver roller and carries the FIPUX brand name.

Galvanized End 1.5-Inch Stainless Steel Conveyor Roller

Galvanized End 1.5" x 16" Stainless Steel Conveyor Roller - Ideal for Warehouses

The Galvanized End 1.5-Inch Stainless Steel Conveyor Roller is the natural direction when the smaller roller and shaft measurements fit the intended conveyor configuration. It combines a stainless steel surface with galvanized end caps and is described for use beneath conveyor belts in assembly lines, warehouses, and manufacturing facilities. The listing identifies one silver roller with an item weight of 1.67 pounds. Its limitation relative to the FIPUX alternative is the smaller roller format, so it is not the choice for a requirement centered on the larger diameter or shaft. The lower listed price is the strongest reason to favor this roller when its dimensions align with the setup.

Final choice by use case

Pick the FIPUX 3.5-Inch Stainless Steel Gravity Conveyor Roller for a conveyor application built around the larger stated roller diameter, 20 mm shaft, built-in bearings, and spring press-in method. Pick the Galvanized End 1.5-Inch Stainless Steel Conveyor Roller for a smaller-format requirement where the lower listed price and 1.5-inch roller diameter are the priority. Both are single silver stainless steel-surface rollers with galvanized end caps, so size and listed price are the clearest deciding factors.
