40 Series 3 Slot Mount – Single Flange Short High-Cycle Linear Bearing

40mm Slider Block – 40 Series

The Linear T-Slot 40mm Slider Block is a maintenance-free, cost-effective alternative to traditional roller wheels and grease-lubricated bearings. Engineered specifically for 40 Series aluminium extrusion systems, this bearing block uses durable, replaceable black nylon sliders to deliver smooth, self-lubricating motion—completely eliminating the need for oil or grease.

Unlike roller wheels or metal bearings that require frequent lubrication and are prone to attracting dust and debris, this solid-state sliding mechanism ensures consistent, quiet performance with minimal wear. The nylon sliders are securely fastened into the aluminium block, providing strength during operation while remaining easy to replace when worn—maximizing long-term reliability and cost efficiency.

Constructed from high-grade aluminium alloy with a silver anodised finish, the block offers excellent corrosion resistance and mechanical durability. The black nylon sliders offer low-friction movement along the T-slot profile, reducing wear and extending service life.

Key Features

• Maintenance-Free Operation – Self-lubricating nylon sliders require no grease or oil, reducing maintenance and keeping systems clean.

• Smooth & Silent Performance – Nylon sliders eliminate noise, vibration, and wear on aluminium profiles.

• Replaceable Sliders – Easily replace worn sliders by unscrewing them, extending the product’s life.
