Product identity and intended use

The Silverstone RMS05-22 is a tool-less sliding rail kit designed for 440mm wide 3U or 4U rackmount chassis. It supports SilverStone RM44, RM46, RM47, RM51 and RM52 models and fits rack cabinets with mounting hole distances between 23.5 and 36.5 inches.

Load capacity and ball-bearing operation

Each kit includes left and right rails built with ball-bearing slides rated for a maximum load of 77.16 pounds (35kg). The tool-less design allows quick installation without specialised hardware and the bearing mechanism provides smooth extension for routine chassis access.

Behaviour under sustained rack use

The rails maintain consistent sliding action when the chassis is fully loaded to the rated capacity during repeated maintenance cycles. The mounting range of 595 to 936mm accommodates variable cabinet depths without requiring rail modification or additional brackets.

Questions about this item

How do I install the tool-less sliding rails into a rack cabinet, and what spacing mistake should I avoid?

Mount the left and right rails into rack cabinets with mounting-hole distances between 23.5 and 36.5 inches (595–936 mm); the common error is setting the rails outside this range so the chassis cannot lock in.

What maintenance will the ball-bearing slides need over time?

The ball-bearing mechanism is sealed and requires no routine lubrication; if a rail becomes stiff or noisy, replace the affected rail rather than attempting to service the bearings.

At what load limit will the rails show deflection first during sustained use?

The kit is rated for a maximum load of 77.16 pounds (35 kg); exceeding this weight will cause the rails to deflect or bind before any other component fails.
