DIN + Extended Body

Combines DIN's larger OD and thicker race wall with extended body length for maximum load capacity in European-standard housings.

Highest DIN Load Rating

Dynamic ratings 421–7,550 N, static 804–20,000 N — the highest available in the DIN cylindrical linear bearing format.

Moment Load Resistance

Extended contact length improves stiffness against pitching and yawing moments from offset loads typical of cantilevered assemblies.

GCr15 Chrome Steel

AISI 52100, HRC 58–64. DIN race wall exceeds ISO equivalent, providing additional fatigue life under combined loading.

Dual Lip Seals

NBR seals −20°C to +80°C. Factory NLGI-2 grease. OD and housing dimensions identical to LME...UU for housing compatibility.

9 Bore Sizes

8 mm to 60 mm covering DIN shaft diameters where extended-body high-load guidance is required.

GCr15 Chrome Steel

AISI 52100 equivalent. Through-hardened HRC 58–64. Ball tracks precision-ground to Ra 0.2 µm for full-film lubrication at rated load.

PA66-GF30 Retainer

Glass-fibre-reinforced nylon cage. Maintains 360° ball spacing. Resistant to mineral oils, greases, and dilute acids across the service temperature range.

NBR Dual Lip Seals

Contact seals on both end faces. Retain grease and exclude dust, swarf, and splash. Operating range −20°C to +80°C with standard NLGI-2 grease.

Laser Cutting & Engraving

Galvo-mirror positioning bridges and cutting-head gantries in CO₂ and fibre laser systems require bearings capable of high traverse speeds with negligible stick-slip.

Optical Instrument Stages

Microscope focus drives, spectrometer sample stages, and telescope focuser assemblies need zero-backlash linear guidance to preserve optical alignment under vibration.

Packaging & Labelling Lines

High-cycle pick-and-place heads and label applicators use LM series bearings for smooth, repeatable shaft travel at up to 600 strokes per minute with minimal maintenance intervals.

Medical Device Stages

Syringe pump drives and diagnostic cartridge dispensers rely on consistent linear force transfer and contamination resistance to meet IEC 60601 reliability requirements.

🔎 Alignment Check

After installation, traverse the shaft manually through the full stroke. Resistance should be uniform. A stiff patch indicates shaft misalignment exceeding 0.03 mm/100 mm — correct the housing position before powering the drive.

🔧 Retention Method

Use snap rings, end caps, or adhesive retention (Loctite 638) depending on housing design. Ensure the bearing cannot shift axially under dynamic loading; axial play causes fretting at the ball-race contact.

📈 Re-lubrication Interval

Under typical duty (moderate load, ambient temperature, no contamination), re-lubricate every 500 km of travel or 6 months, whichever occurs first. Harsh environments or high temperatures shorten this interval significantly.

⚙ Shaft Specification

Match the shaft to h6 tolerance ground on bearing-quality steel hardened to HRC 60 or above. Surface roughness should not exceed Ra 0.4 µm. An undersized or soft shaft accelerates ball-track wear and reduces service life by up to 70%.

①

Confirm Configuration

Confirm DIN housing dimensions. LME OD is larger than ISO — cannot be used in ISO housings. Verify housing was designed to DIN before ordering.

②

Select Bore & Verify Housing

Match bore to shaft nominal diameter. Confirm housing counterbore depth accommodates the longer LUU body length L.

③

Calculate Load & Life

Calculate L10 = (C/P)³ × 50 km. Include moment load component using ISO 10285 procedure before comparing with rated C.
