E-line Swivel 4"x2" Polyurethane (TPU) USA-Made Wheel 4"x4.5" Plate Caster; Part# ES4X2TUMB

About This Caster - ES4X2TUMB

Choose this 4-inch swivel for a cart that gets pulled in a train or moved at speed, where the bearing has to run true and cool at a faster roll instead of a hand-push pace.

This is the precision-ball-bearing version of the 4-inch TUM swivel. The precision bearing is held to a tighter tolerance, so it runs smoother and cooler behind a tug or on a powered line than a plain bearing. The Pemco TPU polyurethane tread on a polypropylene core stays non-marking and carries the load through the route. It is the 4-inch E-line caster for tow-line and higher-speed duty.

Ideal applications

• Tow-line cart trains pulled by a tug, warehouse floor
• Carts moved at speed on a powered line, sealed concrete
• Higher-cycle transport where bearing heat matters, multi-shift

Skip the precision bearing if the cart is hand-pushed at walking pace; the Delrin-bearing ES4X2TUMD is maintenance-free and costs less for that duty.

Pairs with: matching 4-inch rigids on a tow-line cart, and a drawbar where used.

Wrong fit? Hand-push pace? See the Delrin ES4X2TUMD in the Pemco collection.
