Pro-source PRO-SC0325 Spherical Ball Caster 3 Inch

Product Description

The PRO-SOURCE PRO-SC0325 is a swivel spherical ball caster designed for mobile equipment, carts, and industrial fixtures that require smooth, multi-directional movement. Built with a solid poly donut-shaped wheel measuring 3 inches in diameter and 1.7 inches wide, this caster rides on a ball bearing for low-resistance swivel action. The steel frame carries a zinc finish for basic corrosion resistance. At a rated load capacity of 114 kilograms, it handles moderate industrial and commercial loads. The round stem mount measures 1.38 inches in length, making it compatible with standard stem-mount sockets. Maintenance technicians, facilities staff, and equipment assemblers are the typical installers.

This caster suits light-to-medium-duty mobile equipment in shop, warehouse, and facilities environments. The 5.5-inch mounting height fits standard cart and fixture frames where consistent floor clearance is required. The solid poly wheel resists moisture and many common shop fluids without requiring lubrication. Eight wheels are included per package, making this listing appropriate for multi-caster equipment builds or full-set replacements. The red wheel color provides easy visual identification in mixed-caster inventory settings.

Installation Notes

Install and removal requires no specialized tools beyond a socket or open-end wrench sized to the stem hardware. Power down or de-energize any motorized equipment before servicing casters. Confirm the stem socket receiver diameter matches the round stem before pressing or threading the caster into place. Inspect load ratings of all casters in a set to ensure the combined rating meets or exceeds the total loaded equipment weight.
