Application fit notes
LME Series Metric Flange Linear Bearing
European machinery often uses flanged linear bearings where the bearing mounts from the front face of a housing plate rather than being pressed in from the side. The LME series follows the European metric dimensional standard (DIN ISO 10285 LME variant), with a circular flange and equally spaced bolt holes. The open type (OP) has a longitudinal slot that allows the bearing to be adjusted or locked against rotation inside the housing. Shaft diameters run 8–60 mm. Outer rings are GCr15 chrome steel; balls are GCr15 with a PA66-GF retainer. These are used as direct replacements for SKF LMEF, INA KGNOZ, and other European-dimension flange bearings.

Key Features
Flanged Bolt-On Mounting
Circular flange with 3-bolt pattern matches standard LME housing plates used in European machine tools and automation lines. No press-fit tooling needed; bolts directly to the face plate.
3-Bolt FlangeOpen Slot for Adjustable Fit
The longitudinal clearance slot on the OP type allows slight radial adjustment inside the housing and prevents rotation without an external lock ring. Useful when replacing worn bearings in existing housings that may have slight bore variation.
OP Open TypeEuropean Metric Dimensions
Follows DIN ISO 10285 LME envelope dimensions. Confirmed dimensional compatibility with SKF LMEF, INA KGNOZ, and equivalent series — buyers can validate against their own housing drawings before ordering.
DIN ISO 10285Replacement buyers: If you are upgrading or maintaining European-origin equipment, check your housing bore diameter and bolt-circle against the LME series dimension table (available upon request). The OP slot orientation can be specified at order stage.
Typical Applications
LME flange bearings appear in European CNC machining centers, woodworking machines, laser cutting heads, medical imaging tables, and packaging equipment where the flanged design simplifies front-access installation and replacement. The open type is especially common in split housings on textile and printing machinery.
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 (LME8–LME30) is 10–20 business days; larger sizes available upon request.
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.
