Furniture Caster
Universal PU Wheel Furniture Casters For Office Chairs
Polyurethane tyred swivel casters with a plastic body and a metal split key ring stem.
A universal swivel caster with a polyurethane wheel, a plastic body and a metal split key ring stem, published at 2.625 inches high. PU is the softer of the two common wheel materials, which is why this is the caster specified when office chairs have to roll on wood, laminate or tiled floors without marking them.
- Polyurethane tyre chosen where hard floors have to be protected
- Metal split key ring stem, the common office chair grip ring pattern
- Plastic body keeping weight off the chair base
- Universal swivel action for office seating and mobile units

Problems It Solves
What This Model Is Specified To Fix
- New Hard Floors Get MarkedStandard nylon wheels concentrate load into a narrow contact line and score wood and laminate. A PU tyre spreads the contact patch.
- A Five Dollar Part Retires A Good ChairReplacing five casters is a fraction of the cost of replacing a chair, provided the right stem is identified.
- The Stem Does Not Match The BaseCaster stems vary between chair makes. Checking a sample against an existing caster before a building-wide order avoids a useless delivery.
- Spares Arrive After The FurnitureCasters ordered separately turn up weeks behind the seating. Adding them to the furniture order closes that gap.

Comparison
How It Compares With The Alternatives
| Compared With | What Changes |
|---|---|
| Nylon wheel casters | Nylon is harder and rolls better on carpet, but it is what marks wooden and laminate floors. PU is the correct choice on hard floors. |
| Threaded stem casters | A grip ring stem pushes in and pulls out without tools, which is why office chair bases use it - but it must match the socket. |
| Replacing the chair | Five casters cost a fraction of a chair, and in most cases the wheel is the only worn part. |
Use Guide
Pull one existing caster and measure the stem diameter and length
Compare overall caster height, not wheel diameter, so seat heights do not change
Confirm the duty is seating rather than a loaded trolley
Order per chair with a working margin of spares

Furniture Casters PU Wheel Questions
What size is this caster?
2.625 in high, 0.5 in wide and 0.562 in long, as published for this model.
What stem does it use?
A metal split key ring stem - the grip ring pattern most office chair bases are drilled for.
Why choose PU over nylon?
PU is softer and spreads the contact patch, so it is the usual specification where wooden, laminate or tiled floors have to be protected.
Will it fit my existing chairs?
Stem diameters vary between makes. Pull one caster from an existing chair and check a sample before ordering a building-wide quantity.
Can casters be added to a furniture order?
Yes, and it is the simplest way to make sure the seating and the spares arrive together.
