How do I determine the correct caster load rating?

Divide the total loaded equipment weight by the number of casters, then add a safety factor (typically 25–30%) to account for uneven loading and dynamic forces during movement.

Why do some casters fail before reaching their rated capacity?

Load ratings assume ideal conditions. Floor transitions, shock loads, continuous static loading, and improper installation can reduce service life.

Can casters remain under a heavy static load for years?

Yes, but wheel material selection is critical. Some materials resist flat spotting and compression set better than others.

Why is my server rack difficult to move even though the casters are rated correctly?

Rolling resistance is affected by wheel diameter, tread material, bearing type, floor condition, and load distribution.

Data Centers

Designed to provide durable solutions for use within data centers, storage of IT & electronic processing equipment, Uninterruptable Power Supply (UPS) and cooling systems, these casters are built for high load capacity where overall height is a limiting factor.

Engineered for Reliability

Featured Series

BLS/BMS business machine casters are one of the most durable low-profile series to date. Designed to achieve the highest load capacity in a sleek, low-profile design, BLS/BMS casters are made with heavy gauge steel for maximum capacity. Each unit is finished in trivalent zinc, and are RoHS compliant. Innovative wheel materials provide ease of mobility and trusted performance.

BDS/BDR casters are a sleek, low profile caster series designed for business machines and other applications where low-clearance is necessary. Heat-treated steel provides increased strength and rig stability, and a highly-polished chrome finish provides a lustrous appeal. Precision ball wheel bearings provide ultimately mobility and moving ease.
