The SSR30XW1UU THK belongs to THK SSR compact wide-flange linear guide series, fitted with double-sided UU integrated contact seals. Optimized for compact installation space and medium-heavy radial load, this wide-body linear block realizes stable four-direction load bearing, low running noise and outstanding anti-pollution capacity, widely recognized for lightweight precision linear transmission.
In accordance with JIS B6335 linear motion standard: overall block width 82 mm, mounting height 38 mm, installation hole spacing 60 mm, edge chamfer 1.0×45°, precision tolerance grade C3. The widened flange structure reserves abundant bolt installation positions to improve overall mounting stability.
Block base and raceway substrate adopt S55C medium carbon structural steel, overall quenched to HRC 60~62 with excellent surface hardness, wear resistance and structural anti-deformation property. Circulating steel balls are manufactured from 100Cr6 high-purity bearing steel for superior contact fatigue resistance; glass-fiber reinforced PA66 plastic retainer steadily constrains rolling elements to avoid falling-off and lower operating friction.
Key production workflows cover precision hot forging, CNC finish machining, integral quenching & low-temperature tempering, raceway form grinding and ultra-precision superfinishing. Forging optimizes internal metal fiber arrangement; heat treatment removes internal residual stress; superfinishing cuts raceway roughness to minimize kinetic friction loss.
Calculated following ISO 14728 linear bearing standard, its L10 rated service life hits 56000km under rated load, normal reciprocating speed and proper lubrication. Core life influencers include actual applied load, travel frequency, mounting parallelism, grease status and on-site dust concentration.
This THK SSR30XW1UU block is commonly equipped on light CNC equipment, automated assembly lines, food packaging machinery, printing devices and small-scale automotive tooling. Its wide flange simplifies direct base mounting without auxiliary fixing plates and fits compact equipment layout perfectly.
Carry out refueling maintenance every 200 working hours with THK dedicated linear guide grease, single filling volume 0.35~0.5g. Wipe rail surface to clear dust regularly; inspect seal aging and moving smoothness, replace sealing components once grease leakage or abnormal clatter appears.
Clean mounting datum and guide rail before assembly; slide block onto rail slowly without forced knocking, fasten fixing bolts at 24~28N·m torque and control parallelism deviation below 0.02mm/m. Complete full-stroke reciprocating test after installation; wear anti-cut gloves during assembly for operational safety.
