User Pain Point + Solution + Data
Maintenance teams running European-origin CNC machining centers, woodworking machines, and packaging lines often need to replace flanged linear bearings that mount from the front face of a housing plate, not from the side. Press-fit bearings require boring tools and disassembly of the shaft; the LME series bolts directly to the face plate with a 3-bolt circular flange. The open type (OP) adds a longitudinal slot for radial adjustment inside housings with slight bore variation, which is common on older equipment. Shaft diameters span 8β60 mm per DIN ISO 10285 LME, with GCr15 chrome steel outer rings and balls at HRC 60β64 and PA66-GF retainers. Dimensional compatibility covers SKF LMEF and INA KGNOZ series.

Product Advantages
Bolt-On Front-Face Mounting
Circular flange with 3-bolt pattern matches standard LME housing plates used in European machine tools. No press-fit tooling or bore machining needed - unbolt the old bearing, bolt on the new one. This cuts replacement downtime from hours to minutes on production lines.
3-Bolt FlangeOP Slot for Worn Housings
The longitudinal clearance slot on the OP type allows slight radial adjustment inside housings that may have bore variation from years of service. The slot also prevents rotation without an external lock ring. Useful when maintaining older European equipment where housing bores are no longer pristine.
OP AdjustableDIN ISO 10285 Drop-In
Envelope dimensions follow DIN ISO 10285 LME. SKF LMEF, INA KGNOZ, and equivalent European-series bearings can be replaced directly. Buyers should verify outer diameter, flange diameter, bolt-circle, and length against their housing drawing before ordering.
DIN ISO 10285GCr15 Chrome Steel, HRC 60β64
Outer ring and balls are GCr15 (52100 equivalent), induction-hardened to HRC 60β64. PA66-GF retainer maintains ball pitch under thermal cycling. UU type carries double rubber seals for dust resistance; OP type runs open for split-housing applications.

Manufacturing, Exhibition & Quality Control
Production Process & Quality Assurance
Process: GCr15 raw tube -> CNC turning (outer ring, flange, raceway groove) -> induction hardening (HRC 60β64) -> precision grinding (raceway) -> ball circuit assembly with PA66-GF retainer -> seal installation (UU type) or slot machining (OP type) -> 100% running smoothness test -> packaging.
Quality testing: Bore and flange dimensions verified on air gauges (Β±2 Β΅m), dynamic load validated on endurance rig, seal effectiveness tested with dust ingress simulation. Exhibitions: Regularly exhibited at PTC Asia (Shanghai), CIMT (Beijing), and Hannover Messe to engage European machinery manufacturers.
FAQ
What is the MOQ and are mixed sizes allowed in one order?
MOQ is 100 pcs per individual size and type. Mixed sizes in one shipment are accepted; each size line needs to meet the 100 pcs minimum. Lead time for common sizes (LME8βLME30) is 10β20 business days; larger sizes available upon request. Sample quantities of 10β20 pieces available for qualified buyers.
Are these a confirmed drop-in for SKF LMEF or INA KGNOZ?
LME series dimensions match the ISO 10285 LME envelope which those brands also follow. We recommend buyers verify outer diameter, flange diameter, bolt-circle, and length against their own housing or the OEM drawing before placing a large order. Sample sets are available.
Can the slot orientation on OP type be customized?
Standard slot is at 90 degrees from the flange bolt hole. Other orientations can be discussed for orders of 500 pcs or more; please note your requirement at inquiry stage.
How are LME bearings packaged for export?
Individual anti-corrosion oiled wrapping in plastic bags, then packed in partitioned cartons (50 pieces per carton for LME8βLME20, 25 pieces for LME25βLME40, 10 pieces for LME50βLME60). Wooden pallet packing available for bulk export orders.
What payment methods do you accept?
T/T (30% deposit, 70% before shipment). L/C at sight for orders above USD 15,000. PayPal for sample orders under USD 2,000. Western Union for small orders on request.
Do you offer OEM branding and custom packaging?
Custom logo engraving on flange face available for 200+ piece orders. OEM branded packaging with buyer design available for 500+ piece orders. Custom seal colors and retainer materials can be discussed for high-volume orders.
