Description

Black finished casters are designed with a semi-gloss black coating, not only enhancing their visual appeal but also providing protection against corrosion.

E-coat is an electrically applied paint coating. It is used as either a decorative or protective coating that enhances the appearance of parts while also protecting the surface of parts. Typical thickness is regulated to range between .0002โ€ to .001โ€ depending on the requirements.

This injection-moldedย Polyurethane wheel can come in 4 different colorsย : red, gray, black, blue.ย  The polyurethane tires are mechanically bonded to a polyolefin center.ย  The wheelโ€™s design features precision sealed ball bearings, and has a durometer of Shore 60D.ย  We recommend these wheels for use above 32F and below 180F.ย  They have injection molded polyurethane tires which are best for use on smooth floors.ย  Avoid use in applications where this is abuse such as shock loads, impact, or floor obstructions, or static (standing) loads.ย  Do not exceed 50% of the rated capacity of the wheel for applications that are parked for prolonged periods.

These caster wheels are BLACK non marking injection molded polyurethaneย tires mechanically bonded to a polyolefin center. They are especially suited for use inย Research Laboratories, Hospitals,ย Food Service, Schools,ย Bakeriesย and other Institutional applications. These caster wheels are easier rolling thanย Gray Rubberย on smooth floors. They withstand exposure to many chemicals and solvents. They can be used in industrial applications which do not involve shock, overloading, abuse, obstructions, poor floors or storage ( standing ) loads.

If you have a static (standing) load, or an application that requires a higher capacity polyurethane wheel in a swivel caster,ย  please consider our liquid cast, Black Polyurethane on Black Spoked Iron Hubย
