DIN Euro Standard

Larger outer diameter than ISO for the same bore provides a thicker race wall and higher load capacity. Compatible with DIN-dimensioned housings only.

Dual Lip Seals (UU)

NBR lip seals retain NLGI-2 grease and exclude contamination. Rated −20°C to +80°C. OP and AJ variants available in same outer dimensions.

Higher Load per Bore

Thicker DIN race wall delivers greater fatigue resistance and higher dynamic/static ratings than equivalent ISO bore size.

GCr15 Chrome Steel

AISI 52100 equivalent, HRC 58–64. Ball tracks ground to Ra 0.2 µm. Flange face squareness 0.02 mm across series range.

PA66-GF30 Retainer

Maintains precise ball spacing around the full 360° circuit. Resistant to mineral oils, greases, water, and dilute acids.

11 Bore Sizes

5 mm to 80 mm covering the full range of DIN-standard shaft diameters in European-designed equipment.

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.

Semiconductor Wafer Handling

Die-bonding pick-and-place machines and wafer-inspection stages operate in cleanroom environments where particulate generation must be minimised and positional repeatability must be sub-micron.

Textile & Weaving Machinery

Rapier and gripper shuttle mechanisms traverse at high frequency, requiring bearings that resist lint contamination while delivering consistent tension-free motion.

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.

🔎 Housing Bore Fit

Press the bearing into an H7-tolerance bore using a press tool that bears only on the outer ring face. Never strike the inner bore. For split housings, tighten retaining screws symmetrically to avoid distorting the outer diameter.

🔧 Lubrication at Assembly

Apply a thin film of lithium-complex NLGI-2 grease to the shaft before insertion. This provides initial lubrication to the ball tracks during the first few strokes before the internal grease charge distributes fully.

📈 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.

①

Confirm Configuration

Confirm housing was designed to DIN dimensions. DIN OD is larger than ISO — using LME in an ISO housing causes interference.

②

Select Bore & Verify Housing

Match bore to shaft nominal diameter. Verify OD and length L against DIN-standard housing bore and counterbore depth.

③

Calculate Load & Life

Calculate L10 = (C/P)³ × 50 km. If life is marginal, upgrade to LME...LUU extended series.
