NTN-SNR profile rail guides are high quality precision products. The BG series of profile guides have a number of options available which can be added to suit different environments such as extra seals for dirty applications or corrosion protective layers for wet applications.
Standard carriages can be preloaded and profile rails precision ground to offer high levels of precision.
The BG series is available with ball chain technology which consists of plastic retaining parts in-between the balls on the linear guide. This keeps the distance between the balls constant, preventing uneven running behaviour and reducing friction and noise.
Various types of corrosion protection are available for the BG series.
BG series Black chrome coating – As the name suggests this is an oxide ceramic layer with a matt black appearance. This coating offers the most basic corrosion protection.
Hard chrome – This coating is applied using a galvanic process and has the appearance of metallic black. This is a harder coating than the standard black chrome and so offers a good standard of protection.
Duralloy TDC coating – This coating offers the highest protection due to an extremely hard and crack free matt grey layer which provides outstanding corrosion protection.
