SBR Aluminum linear ball bearing slider - Plastic/ Nylon retainer/ Steel retainer/ Graphitic copper sleeve

Nylon retainer SBR equivalent SME-GUU.

Steel retainer SBR equivalent SME-UU.

• Plastic bearing: Maintenance-free, anti-dust, waterproof, silent, wear-resistant, oil-free.

• Nylon retainer linear bearing: cost-effective, most popular, smooth running.

• Steel retainer linear bearing: high-temperature resistance, high rigidity, smooth running, and long life, yet a bit noisier than the nylon retainer bearings.

• Graphitic copper sleeve: Oil-free, self-lubricating, suitable for low-speed and high-load equipment, heat-resistant, corrosion-resistant, and anti-aging.
