Black Car Wheel Universal Caster Accessories For Office Chairs

Black Car Wheel Universal Caster Accessories For Office Chairs - Replacement casters designed for enhanced mobility and floor protection

Product Features

• Dual-wheel tread design: The wheel surface incorporates a pattern that increases grip on hard flooring surfaces, contributing to controlled movement and reduced rolling resistance.
• Integrated thread guard: A protective collar surrounds the stem socket to prevent thread damage during installation and removal, which supports the longevity of the caster and the chair leg.
• Low-noise rolling mechanism: A sealed ball bearing system provides smooth rotation while minimizing operational noise, suitable for quiet office environments.

Product Description

This universal office chair caster is engineered as a direct replacement for standard 2-inch stem chair casters. The design principle focuses on distributing weight evenly across two parallel wheels to reduce point load pressure on flooring surfaces such as vinyl, laminate, and hardwood. This configuration aims to address the issue of floor scratches and indentations caused by traditional single-wheel casters.

The product is manufactured to meet general industry standards for office furniture components. The wheel material is a formulated thermoplastic polyurethane (TPU) that balances durability with floor surface compatibility. The internal bearing structure is designed for a specified load capacity to ensure consistent performance under typical office use conditions.

Application Areas

This product is suitable for the following environments:

• Office chairs in corporate, home office, and commercial settings
• Task chairs and operator chairs in administrative workspaces
• Replacement for worn or damaged casters on existing office seating

FAQ

Are these casters compatible with my existing office chair?

Compatibility depends on the stem socket size of your chair. This caster is designed for chairs with a standard 11mm (7/16 inch) inner diameter socket. To confirm, you can measure the inner diameter of the socket on your current chair leg or check the specifications of your chair model. The grip ring stem is a common fitting for many office chairs.

Will these wheels protect my hardwood floors from scratches?

The thermoplastic polyurethane (TPU) material is formulated to be non-marking and softer than traditional hard nylon wheels, which reduces the risk of scratches on finished hardwood, laminate, and LVT floors. The dual-wheel design also distributes weight over a larger surface area compared to a single wheel, which can help minimize indentations. However, regular inspection of the wheels for embedded debris is recommended as a general floor maintenance practice.

What is the process for replacing an old caster?

Replacement is a straightforward process. First, tilt the chair on its side. Firmly grip the old caster and pull straight out; some models may require a slight rocking motion to loosen. To install the new caster, align the stem with the socket in the chair leg and push firmly until the stem is fully seated and the thread guard is flush with the base of the leg. No tools are typically required for this installation method.
