NMR 7MN ZZ Assembly

Miniature Profile Rail Systems, Standard Miniature Assembly Four Mounting Holes, 7MM, Standard Block, End Seal, with Lubrication Storage

Miniature Profile Rail Systems come pre-assembled with runner block and Rail. Options include hole caps, top or bottom mount rail, and various seals.

Precision - NMR Miniatrue linear guide series have three accuracy grades for design selection: Precision (P), High (H), Normal (N).

Material - Regardless of series, MR miniature linear guides use stainless steel processed material.

Unique Ball Re-circulation Desin The stainless steel ball re-circulation hole and channel constructs are fully sealed by plastic frame and end caps. The simple structure substantially reduces contact surface between steel ball and metal, thus reduces noise significantly. The lubrication oil storage embedded in the circulation channel significantly extends the re-lubricating interval, interval, extends life and reduces preventative maintenance.

Lubrication Storage Design - Lubricant injection holes are featured at both ends of the runner block. As the balls circulate during movement of the block, the stainless steel balls carry lubrication oil to the raceway, thus efficiently lubricating the balls and the oil raceway, and achieving long-term, maintenance-free linear motion. This design also provides superb lubricating ability for short stroke movement. A newly-invented embedded lubrication pad design provides a selection of options for machine design.
