YIDI MOTION расширяет линейку продуктов для линейного движения — представлены длинные линейные шариковые подшипники серии LME‑L

YIDI MOTION, a manufacturer of linear motion components, today announced the launch of the LME-L series of longer-type linear ball bearings. Built on the proven LME metric housing interface, the LME-L series extends the overall length and adds recirculating ball circuits, giving design engineers a direct drop-in upgrade when a standard-length bearing is approaching its load, life, or rigidity limit.

Engineered for Longer Life and Higher Loads

The LME-L series targets applications where stroke length, mounting envelope, and load rating push a standard linear ball bearing toward its service limit. By lengthening the outer cylinder and increasing the number of loaded ball train circuits, the series distributes radial load across more balls, lowering contact stress per ball and extending rated travel life without changing the standard metric housing bore.

“Customers told us they needed more load capacity and longer maintenance intervals, but they could not redesign the housing,” said a spokesperson for YIDI MOTION. “The LME-L series answers that directly: same mounting envelope, longer effective bearing length, and double-sealed pre-lubricated operation out of the box.”

Key Features

• Through-hardened steel raceways — high surface hardness for wear resistance and long service life under continuous reciprocating motion.
• Precision-ground ball path — consistent radial runout and smooth, quiet linear travel.
• Integral end seals (UU) — each end is fitted with a rubber seal retainer that retains factory grease and blocks dust, metal chips, and coolant mist, reducing relubrication frequency.
• Extended-length body — the longer span improves moment rigidity and reduces deflection under cantilevered or offset loads.
• Drop-in metric interchangeability — matches the standard LME series housing interface for straightforward replacement or upgrade.
• Customization supported — special bore tolerances, seal materials, and modified end configurations available for OEM programs.

Full Bore Range: 8 mm to 60 mm

The LME-L series ships in nine standard bore sizes, all pre-lubricated with double-end seals as standard:

Specifications are nominal and subject to final factory confirmation. Consult YIDI MOTION for tolerance, preload, and lubrication data before selection.

Типичные области применения

The LME-L series is suited to Cartesian gantry systems, packaging machinery, 3D printing platforms, semiconductor and electronics handling equipment, medical devices, textile machinery, and general automation where a compact, self-lubricating linear bushing is preferred over a profiled rail.

Availability

Standard LME-L series sizes are available for sample and volume orders directly from YIDI MOTION. Custom bore tolerances, seal options, and OEM modifications are supported on request.
