Product Description
LMHC20LUU is a 20mm round flange long-type linear bearing unit (LMHC series), housing an internal LM20LUU linear bearing for smooth, precise linear motion along round shafts. As a flanged linear bearing unit in SQ's product range, the LMHC20LUU features a circular bolt-circle flange and an extended body length (LUU type), delivering enhanced load distribution and greater rigidity - ideal for applications demanding higher stability and longer bearing contact.
Whether used in precision automation or as a flanged linear bearing unit for tools and machining systems, this unit is manufactured under ISO 9001 quality management standards with ROHS-compliant materials, engineered for reliable performance across demanding industrial environments.
Key Features
Round Flange (HC Type)
Circular bolt-circle flange for secure end-plate mounting; evenly spaced bolt holes for stable fastening to panels and housings
Extended Body Length (LUU)
Longer outer cylinder accommodates two ball circuits for improved contact area, load capacity, and moment resistance vs. standard-length units
High-Precision Chrome Steel Housing
Hardened and precision-ground outer cylinder machined for tight dimensional accuracy and long service life
Dual Rubber Seals (UU)
Effective dust and contamination protection on both ends for extended service life and retained lubrication
Low Friction, High Speed
Ball-recirculation design with point contact on hardened shaft ensures smooth, quiet operation at high reciprocating speeds
Easy Mounting
Round flange bolt pattern for secure, straightforward end-plate installation without external clamps or retaining rings
