5 in Replacement Caster Set for Rubbermaid Mobile Shelf Truck - 4

In this review the author assesses the Service Caster 5 in replacement caster set and concludes it is a practical, heavy-duty swap for worn wheels on Rubbermaid Mobile Shelf Trucks. The bottom line: this four-pack of 5 in thermoplastic rubber swivel casters is for users who need a quiet, non-marking wheel with a strong 300 lb capacity per caster; it restores rollability and fit without complicated adapters. The reviewer found the fit, bearings, and zinc-plated hardware to be the single biggest reason to buy when replacing original truck casters.

Key Features

• Direct fit: Designed to replace casters on Rubbermaid Mobile Shelf Truck FG9T4200BLA, FG9T4300BLA and FG9T4400BLA so installation is straightforward and parts align with the existing stem holes.
• 5 in thermoplastic rubber wheel: The 5 in diameter by 1-1/4 in wide wheel offers smooth, quiet rolling on hard floors while minimizing marks on surfaces.
• High capacity: Each caster supports up to 300 lb for a combined 1,200 lb capacity, making these appropriate for loaded utility carts and light industrial use.
• Grip ring stem: The 7/16 in diameter by 1-3/8 in length grip ring stem secures each caster in the truck socket for reliable retention during use.
• Zinc-plated finish: The plated steel components resist corrosion and wear, extending service life in workshop and janitorial environments.

Who It's For

These casters are best for maintenance staff, facilities teams, and workshop owners who already use Rubbermaid Mobile Shelf Trucks and need a like-for-like replacement that restores smooth operation. The soft thermoplastic rubber suits hospitals, offices, and retail floors where quiet, non-marking wheels are important.

Users who require specialty wheel compounds, very high temperature resistance, or custom stem sizes should look elsewhere, since this listing is for the specific Service Caster Series #20 swivel caster with a 7/16 in grip ring stem and standard thermoplastic rubber tread.
