PHGH Series Linear Slide Rail Guide Manufacturer

PHGH Series Definition

PHGH linear guide means heavy load ball square type linear guide which is designed with four row single circular arc groove structure that can bear heavy load, compared to other traditional types of lm guideways. Square linear rail features with equal loading from all directions and self aligning ability, can reduce the mounting error and achieve the high precision level.

picture	name	square block
	material	20 CRmo
	mounting type	top , bottom and both
	steel balls	has balls retainer to avoid balls falling off
	advantage	self-aligning, high rigidity, heavy load, high precision, smooth operation

For PHGH-CA / PHGH-HA series, we can know the meaning of each code as follows: Take size 30 for example:

PHGH-CA/PHGH-HA block and rail type

Type	Model	Block Shape	Height (mm)		Rail Mounting from Top	Rail Length (mm)
Square block	PHGH-CAPHGH-HA		26 ↓ 76			100 ↓ 4000
Application
Machine centers NC lathe Grinding machines Heavy cutting machines				Automation devices Transportation equipment Measuring equipment Devices requiring high positional accuracy
