Miniature linear ball rails from Nook Industries for high-speed running capacity

April 16, 2015 By Danielle Collins 1 Comment

Nook Industries, a leading innovator of linear motion components and systems, has launched a new miniature linear ball rail ideally suited for high-speed, belt-driven mechanisms and carrier designs as well as automation linkage between stations. Offered in three accuracy grades, Precision (P), High (H) and Normal (N), these miniature linear ball rails provide significant maintenance and lubrication advantages.

Nook Mini Ball RailThe three classes allow customers to choose dimensional tolerances of height and width, as well as variations for height and width of different runner blocks on the same position of a guide rail. All classes use stainless steel materials and feature two rows of recirculating balls in a Nook-specific gothic profile. This provides for a 45-degree contact angle with greater surface contact, which provides equal load capacity in all directions.

“Maintenance is made easier through the use of several specially designed Nook features. Low-friction end seals effectively restrict dust while stainless steel endcaps act as scrapers,” said Ronald Giovannone, project manager at Nook Industries. “Most importantly, a unique ball recirculation design, with hole and channel constructs fully sealed by a plastic frame and endcaps, reduces contact surface between steel ball and metal. This reduces noise and adds to lubrication efficiency, reducing preventative maintenance.”

Lubrication is also aided through the use of an efficiently designed system for circulating and storing oil. Injection holes on either end of the runner block deliver oil to the stainless steel balls which also lubricate the raceway, achieving long-term, maintenance-free linear motion. A newly invented, embedded lubrication pad also provides a selection of options for machine design.
