NSK Europe is one the world’s leading manufacturers of roller bearings, linear technology, automotive components and steering systems.

RM Fowler can supply the full range of NSK linear products including ball screw support units.

NSK has recently invested in new materials and production techniques at its Newark UK manufacturing plant. While Newark has manufactured products in the UK for over 100 years it is only recently that they have moved their linear manufacturing to the UK.

NSK ball screws and linear guides can be fitted with their patented K1 units.

K1 units use porous resins containing abundant lubricants to form an integral moulded unit which is fixed to the carriage or nut. When the carriage or nut move fresh lubricating oil is steadily provided from the K1 as it moves along the rail or shaft surface.

Accuracy and Preloading

All NSK linear guide rails are precision ground, however accuracy and stiffness can be increased by having the rails precision ground to much closer tolerances. Accuracy is rated from the highest accuracy of P3 down to P6 and also includes PH, PN and PC.

Preloading is the elimination of clearance between the raceways and roller elements of a linear guide or ball screw. This is achieved by inserting roller elements that are slightly bigger than the space in between the raceways. Various combinations of accuracy and preload are available throughout the entire NSK range.
