Stem Casters – Metro Super Adjustable Casters

Stem Casters designed for versatility and dependable performance on carts and trolleys. Available in four materials to suit floor type and load demands, these casters offer a metal-free polymer housing option alongside traditional rubber and polyurethane wheels. The polyurethane variant is pictured above, and all variants are sold individually to let you tailor your setup precisely.

Features

• Material options with clear load ratings:
  • Resilient: black hard rubber — 800 lb per cart
  • High Modulus: black soft rubber — 800 lb per cart
  • Polyurethane: grey wheel — 1200 lb per cart
  • Polymer housing: all-polymer construction (no metal) — 1200 lb per cart
• Stem-mounted design for straightforward installation on compatible carts
• Color and compound vary by material (rubber variants in black; polyurethane in grey; polymer housing version is metal-free)
• Durable construction tailored to different environments—from vibration damping to heavy-duty payloads
• Sold individually, enabling precise, mix-and-match configurations across a fleet

Benefits

Choose the right caster for the job to improve safety, efficiency, and longevity of your equipment. The 800 lb variants are ideal for everyday carts with moderate loads, while the 1200 lb polyurethane and polymer housing versions provide elevated capacity for heavy-duty applications without relying on metal components. The soft rubber variant helps cushion impacts and reduce floor wear, making it a good fit for sensitive flooring, while the hard rubber option offers durability in tougher environments.

The all-polymer housing option is corrosion-resistant and quieter in operation, eliminating metal contact and simplifying maintenance in clean or wet settings. Since casters are sold individually, you can implement a strategic mix across different carts—matching wheel type to task, floor surface, and payload. Practical use cases include warehouse utility carts, maintenance trolleys, medical or lab carts, and engineering/workshop carts where reliable, load-bearing mobility is essential.

Practical tips: pair higher-capacity polyurethane or polymer housing variants for heavy loads on smooth floors, reserve rubber variants for lighter duties or floor-sensitive areas, and consider replacing worn casters in a staged, cart-by-cart approach to minimize downtime.
