When ergonomics and durability are critical for your equipment, trust this proven 4" x 2" heavy-duty kingpinless swivel caster with brake featuring our industry-leading MAX-Efficiency polyurethane wheel. 71XMB42S-TB is highly ergonomic and designed and constructed to withstand impact and shock for lasting and safe mobility, rated at a 800 lb. dynamic load capacity per caster. It is perfect for both ergonomic hand-pushed tasks and power-towed applications. The precision-machined and heat-treated kingpinless raceway ensures smooth swiveling and durability even in the most punishing applications, eliminating the possibility of kingpin stretching and failure which is the most common cause of failure in traditional casters. A positive locking side activated brake securely locks the wheel when engaged and is easy to disengage. Key features of this caster include:
-
Quiet and ergonomic rolling, rugged kingpinless caster rig handles shock and impact
-
Wheel: maintenance-free and highly ergonomic maroon MAX-Efficiency wheel outlasts leading competitor by 2x in wheel life (85A durometer), rejects debris, reduces noise, and protects floors–standard with sealed precision ball bearings
- ANSI ICWM tested to 800 lb. dynamic load capacity per caster
-
Top Plate: 4" x 4-1/2" overall top plate constructed of 5/16" thick AISI 1045 steel welded and heat treated for longer life
-
Swivel Section: 3/8" ball bearings in heat-treated precision machined raceway for durability and smooth swiveling with a zerk for future grease maintenance
-
Zinc plated for corrosion resistance and lasting finish
With a fully heat-treated construction, our 71 Series is highly suitable for rugged environments and high-impact situations. They are more durable than competitors' case or induction-hardened construction and outlast and outperform conventional kingpin designs. Say goodbye to kingpin failure, the primary cause of caster malfunction, and hello to enhanced ergonomics with our highly reliable kingpinless casters.
