Bolt Customization
Customizable Thread Lengths: Thread engagement and bolt lengths can be fully extended, shortened, or modified to drop perfectly into your specific engineering blueprint.
Bespoke Thread Pitches: Custom pitch configurations can be threaded to match your pre-existing internal nut housings or proprietary furniture frames.
Product Features
Reinforced Riveted Core Construction: Unlike standard office chair wheels, the RUTW series utilizes a heavy-duty riveted center axle, dramatically increasing structural rigidity under continuous lateral movement.
Dual Material Options (Nylon / PU): Available in standard rigid Recycled Nylon for maximum roll-efficiency, or upgraded Polyurethane (PU) soft-tread coating to deliver silent mobility and zero-scratch protection for high-end hardwood and tile floors.
Industrial 360-Degree Swivel Race: Built with an omnidirectional swivel bearing mechanism that prevents jamming or lagging under maximum structural load limits.
Quality & Compliance
Exceeds ANSI/BIFMA Performance Standards: Validated through rigorous cyclic testing and drop-impact tests to guarantee long-term operational durability.
Certified Eco-Friendly Manufacturing: Features certified non-toxic recycled nylon polymers and restricted chemical finishes, complying fully with international RoHS and REACH directives.
