Nine bore sizes from 1/4 inch to 2 inches, available with double-end seals, clearance-adjustable rings, or open-side housings for inch-based automation and retrofit markets
YIDI MOTION, a manufacturer of linear motion components, today announced the LMB series of inch-size linear ball bearings, engineered for equipment builders and retrofit engineers working with imperial-dimension shafts. The series spans nine bore sizes from 1/4 inch to 2 inches and is offered in three housing configurations to match different mounting and preload requirements.
Three Configurations, One Inch-Size Platform
The LMB series is built around a common inch-dimension envelope, with three structural variants addressing different application needs:

AJ (clearance-adjustable) and OP (open) variants carry the same nominal OD and length with corresponding ball row counts and weights as listed in the factory main dimension table. Values are nominal and subject to final factory confirmation; consult YIDI MOTION for tolerances, preload classes, and lubrication data before selection.
代表的な用途
The LMB series is targeted at Cartesian gantries, packaging and labeling equipment, 3D printers, CNC router and engraving tables, semiconductor handling fixtures, medical devices, textile machinery, and aftermarket replacement of inch-dimension linear bushings installed in North American and UK-specified equipment.
Availability
Standard LMB series sizes in UU, AJ, and OP configurations are available for sample and volume orders. Custom bore tolerances, seal materials, and OEM modifications are supported on request.
