Dual-Wheel Industrial
Load Capacity: 200 to 400 lbs.
An exceptionally strongdual-wheel caster for
applications where heavy loadcapacity, low overall height, and floor
or carpet protection is required.Each wheel rolls independentlyfor easy swiveling under heavy,
low profile loads.
Used extensively on:
• Computer Frames
• Electronic Enclosures
• Copy Machines
• Disk Storage Devices
• Display Racks
• Airport Terminal Stands
No other low profile caster matchesthe strength and performance of the 30 series. Available in either standard bright zinc or optional
black oxide finishes.

SERIES Quality Features• FOUR-SIDED, DOUBLE BALL RACEWAY.
Hardened steel ball bearings touch upper andlower swivel raceway “on all four sides.” Thisprotects the pin from shock loading for freeswiveling under heavy loads.
• HEAT-TREATED MOVING PARTS.All moving parts are hardened to a precise molecular depth and Rockwell hardness. Thisextends caster life under rugged conditions andshock loads.
• RACEWAY DUST CAP. Dust cap protects the raceway from contamination by dust, dirt, moisture,
and other environmental debris.• LOW OVERALL HEIGHT.
Heavy loads are supported by two wheelsthat roll independently to assure easy maneuver-ability in applications where a low profile isrequired.
Options• Thumb-Style Wheel Brake
• Conductive or Static-Dissipative Wheels
• Gray, Non-Marking Wheels
• Power Coated or BlackOxide Finishes
• Maintenance-Free SwivelBearings
