Linear bush
Linear ball bush LM series

High-precision and high quality linear motion bearing offered by Linear bearing specialist manufacturer

HEPHAIST SEIKO manufactures compact, easy-to-use and high performance linear ball bearings by rationally arranging solid plastic-structured cage, steel balls and snap rings on the outer shells of rational design structure based on the unique idea.
We first started the mass production of miniature series of linear ball bearings in the world. Compact, easy-to-use and high quality linear ball bearings of HEPHAIST SEIKO are important mechanical elements essential to mechatronics systems for speeding up, downsizing and energy saving.

This time, HEPHAIST SEIKO has first succeeded in the development of LM-2 with the shaft diameter of 2 mm in the world.

High precision
Each accurately machined component ensures high precision. In order to maintain the accuracy of linear bearing, it is necessary to properly adjust a clearance between the bearing and shaft. HEPHAIST SEIKO can adjust the clearance to your needs and offer the combined product with shaft.
High performance
Four to six lines of balls arranged within a narrow space, supported by a tough outer shells, smoothly move against external forces applied from various directions forming an energy-efficient bearing with less sleeve resistance.
Low noise
The plastic rtainer ensures low friction and smooth ball cycles with less noise during travelling.
Long life
Long life can be expected due to proper material of each component, fine ball orbit precisely hardened and large load rating.
High rigidity
Integrated flange type with cold forging has been developed. Different from the jointed flange type, it ensures high rigidity, machining accuracy and reliability. It also contributes to impact resistance and vibration resistance in actual use.

LM: Standard type LME: Standard EU type LMB: Standard type in inches
Straight cylindrical type, with a wide lineup from 2mm to 60mm of inscribed circle diameter. Straight cylindrical type in millimeters. Because of EU-adopted millimeter measurement, the dimensional allowance is different from that for Japan. Straight cylindrical type in inches.
LMF: Round flange LMK: Square flange LMH : Double shear flange
Provides high rigidity due to cold forged integral structure and allows man-hour for assembly to be decreased because of permitted direct fixing with bolts. Provides high rigidity due to cold forged integral structure and allows downsizing of equipment because of permitted attachment with lower core height than round flange. Provides high rigidity due to cold forged integral structure and allows downsizing of equipment because of permitted attachment with lower core height than square flange.
L: Long type LMF_L: Round flange long LMK_L: Square flange long
Two lines of standard type ball bearing cages are arranged, providing high rigidity. Provides high rigidity due to cold forged integral structure and allows man-hour for assembly to be decreased because of permitted direct fixing with bolts.

Provides high rigidity due to cold forged integral structure and allows downsizing of equipment because of permitted attachment with lower core height than round flange.

LMH_L: Double shear flange long OP: Open type AJ: Adjustable type
Provides high rigidity due to cold forged integral structure and allows downsizing of equipment because of permitted attachment with lower core height than square flange. Open type cropping a part of external cylinder and that of ball bearing cage.

With slitting on the external cylinder, the inscribed circle diameter can be adjusted.

SH: Type with housing
Can directly be attached with frame or table because of the incorporated linear ball bush into aluminum housing and high precision machining.
