45# Tempered Long Guide Rail Mount Base | Linear Module Sliding Adjustment Stand

This long guide rail base is integrally gantry CNC milled from solid 45# steel plate, specially designed for linear slide tables and linear guide assemblies. A long slotted adjustment groove and multiple threaded mounting holes are machined in the center, with locating holes on both ends. Tempering heat treatment improves structural rigidity, and black oxide finish provides anti-rust protection. The long slot allows flexible position fine-tuning for long-stroke automation transfer equipment.

Core Specs

Application Industry: Custom automation linear slide tables, long-travel transfer modules, linear guide fixing base, fixture sliding adjustment mechanism, conveyor sliding support

Machining Process: 45# steel blanking → tempering heat treatment HB220~250 → long gantry CNC contour milling → long slotted groove precision machining → M4/M5/M6 tapping & locating hole drilling → edge deburr & radius chamfer → full black oxide anti-rust finish

Tolerance Standard: Total length tolerance ±0.04mm; slot parallelism ≤0.03mm; thread hole position ≤0.02mm; mounting flatness 0.05mm per meter

Heat Treatment Standard: Tempered 45# steel, hardness HB220-250 for improved deformation & wear resistance

Production Equipment: Large gantry machining center, long-stroke CNC mill, tempering furnace, tapping center, black oxide production line

Optional Post-Treatments: Tempering, deburr & chamfer, black oxide, phosphating, surface quenching

Lead Time: Sample order 4~5 working days, bulk order 7~12 working days

Advantages

✅ One-piece solid long steel plate without splicing, superior integral rigidity, no bending or vibration under high-speed long-stroke sliding

✅ Extra-long central slotted groove allows wide-range forward & backward position adjustment to compensate frame machining tolerance

✅ Multi-size threaded holes arranged in zones to mount linear guides, limit stops and sensor brackets all in one block

✅ Tempered 45# steel resists compression and abrasion, far longer service life than ordinary carbon steel under repeated reciprocating motion

✅ Full black oxide coating isolates workshop coolant and moisture, delivering stable anti-corrosion performance in harsh production environments

Tempered 45# long guide base with adjustable long slot for wide compatibility; solid rigid structure anti-deformation, dedicated mount for linear slide modules.
