Linear Bearing LMK12LUU LMK12 LUU Long Linear Bearing LMK 12LUU LMK 12MM Square Flange Type Bearings 122157 mm Linear Ball Bearings

BearingsStructure and FeaturesLinear Bushing model LM is a linear motion system used in combination with a cylindrical LM shaft to perform infinite straight motion. The balls in the loaded area of the nut are in point contact with the LM shaft. This allows straight motion with minimal friction resistance and achieves highly accurate and smooth motion despite the small permissible load.Model Number: LMK12LUUCoatings: Antirust oilTorque Capacity: 12*21*57mmSurface Roughness: Ra 0.05Structure: Linear BearingMaterial: 52100 Chrome SteelApplicationThe nut uses high-carbon chromium bearing steel and its outer and inner surfaces are ground after being heat-treated.The Linear Bushing is used in a broad array of applications such as slide units of precision equip-ment including OA equipment and peripherals measuring instruments automatic recorders and dig-ital 3D measuring instruments industrial machines including multi-spindle drilling machine punching press tool grinder automatic gas cutting apparatus printing machine card selector and food pack-ing machine.InterchangeabilitySince the dimensional tolerances of the Linear Bush's components are standardized they are in changeable. The LM shaft is machined through cylindrical grinding which can easily be performed and it allows highly accurate fitting clearance to be achieved.Highly Accurate Retainer PlateSince the retainer which guides three to eight rows of balls is integrally molded it is capable of ac-curately guiding the balls in the traveling direction and achieving stable running accuracy.Small-diameter types use integrally molded retainers made of synthetic resin. It reduces noise gen-erated during operation and allows for superb lubrication.Wide Array of TypesA wide array of types are available such as standard type clearance-adjustable type open type long type and flangedHelp others learn more about this product by uploading a
