Standard Stainless Steel THK Linear Bushing Linear Motion System, For Industrial

Product Details

Linear 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. The 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 equipment including OA equipment and peripherals, measuring instruments, automatic recorders and digital 3D measuring instruments, industrial machines including multi-spindle drilling machine, punching press, tool grinder, automatic gas cutting apparatus, printing machine, card selector and food packing machine.Types Standard TypeWith the Linear Bushing nut having the most accurate cylindrical shape, this type is widely used. There are two series of the Linear Bushing in dimensional group.Model LM Metric units series used most widely in Japan.Model LM-MG Stainless steel version of type LM.Model LME Metric units series commonly used in EuropeOpen TypeThe nut is partially cut open by one row of balls (50° to 80° ). This enables the Linear Bushing to be used even in locations where the LM shaft is supported by a column or fulcrum. In addition, a clearance can easily be adjusted. Models LM-OP/LME-OP Model LM-MG-OPClearance-adjustable TypeThis type has the same dimensions as the standard type, but the nut has a slit in the direction of the LM shaft. This allows the linear bushing to be installed in a housing whose inner diameter is adjustable, and enables the clearance between the LM shaft and the housing to easily be adjusted. Models LM-AJ/LME-AJ Model LM-MG-AJLong TypeContaining two units of the standard retainer plate, this type is optimal for locations where a moment load is present and reduces man-hours in installation. Model LM-L…………Standard typeFlanged Type (Round)The nut of the standard type Linear Bushing is integrated with a flange. This enables the Linear Bushing to be directly mounted onto the housing with bolts, thus achieving easy installation. Model LMF……………Standard type Model LMF-M…………Made of stainless steelFlanged Type (Square)Like model LMF, this type also has a flange, but the flange is cut to a square shape. Since the height is lower than the circular flange type, compact design is allowed. Model LMK Standard type Model LMK-M Made of stainless steelFlanged Type (Round) - LongThe nut of the long type Linear Bushing is integrated with a flange. This enables the Linear Bushing to be directly mounted onto the housing with bolts, thus achieving easy installation. Containing two units of the standard retainer plate, this type is optimal for locations where a moment load is present. Model LMF-L Standard type Model LMF-ML Made of stainless steelFlanged Type (Square) - LongLike model LMF-L, this type also has a flange, but the flange is cut to a square shape. Since the height is lower than the circular flange type, compact design is allowed. Model LMK-L Standard type Model LMK-ML Made of stainless steelLM Shaft End Support Model SKAn aluminum-made light fulcrum for securing an LM shaft. The LM shaft mounting section has a slit, enabling the linear bushing to firmly secure an LM shaft using bolts.Linear Bushing Model SCIt is a case unit where the standard type of Linear Bushing is incorporated into a small, lightweight aluminum casing. This model can easily be mounted simply by securing it to the table with bolts.
