THK SRS / RSR Series Linear Blocks&Rail
SRS(caged‑ball) / RSR(full‑ball) miniature linear guides, rail width 4‑25 mm, ultra‑compact dimension. Carbon‑steel and stainless‑steel options; stainless‑steel version for humid, corrosive and clean‑room environment. Two‑row 45° ball contact for four‑direction load capacity, multi‑orientation mounting and good interchangeability. Applied in semiconductor equipment, medical instruments, electronic assembly and miniature precision instruments.
PMI MSA Series DLinear Blocks&Rail
PMI MSA series is heavy‑load high‑assembly ball linear block. Adopts 4‑row 45° gothic‑arc ball contact design with equal load‑capacity in four directions and self‑aligning feature to absorb mounting deviation. Built‑in lubrication channel for even grease distribution. Available in square(S), flange(E), top‑mount(A), and extended‑length LS/LE/LA versions for higher load and rigidity. Multiple precision grades N/H/P/SP/UP with preload options. Widely used in machining centers, CNC machine tools, laser equipment and heavy‑duty automation machinery.
PMI MSB Series DLinear Blocks&Rail
PMI MSB low‑profile ball linear block features lower mounting height for space‑saving layout. 4‑row ball design provides equal four‑direction load capacity and self‑aligning performance, low friction and low noise. Versions: square(S), short‑square(TS), flange(E), short‑flange(TE). Light‑weight and cost‑effective with full precision grades. Suitable for robotic arms, handling mechanisms, compact automation and electronic equipment.
PMI MSR Series DLinear Blocks&Rail
PMI MSR roller‑type linear block uses rollers instead of balls for larger contact area, much higher rigidity and load‑capacity than ball‑type guides. Excellent moment‑resistance and shock‑load tolerance. High‑precision grade P and above available. Extended‑length LS/LE blocks further boost load rating. Applied for gantry machine tools, heavy‑duty machining centers and heavy‑load handling stations.
PMI MSC / MSD Series DLinear Blocks&Rail
PMI MSC / MSD miniature linear blocks, minimum rail width 7 mm. MSC: carbon‑steel; MSD: stainless‑steel for humid & corrosive environment. Two‑row 45° ball contact, ultra‑compact size, low friction, multi‑orientation mounting. Interchangeable design, slider or rail can be replaced separately. Widely used in medical instruments, semiconductor inspection, electronic assembly and miniature precision equipment.
PMI SME Series DLinear Blocks&Rail
PMI SME ball‑chain silent high‑speed linear block adopts resin ball‑chain separator to eliminate ball‑to‑ball friction, greatly reducing noise, improving high‑speed stability and extending lubrication interval. Inherits 4‑row 45° ball four‑direction equal‑load and self‑aligning performance. Flange EA/LEA and square SA/LSA options. Ideal for high‑speed automation, long‑travel equipment and low‑noise required applications。
