Slide Block HSR20R1SS GK Linear Motion Ball Bearing 20x44x30mm

The HSR20R1SS GK is global standard HSR series interchangeable separate linear guide block (GK code means rail and slider sold separately without matched set). It adopts 4 rows steel balls arranged at 45° contact angle to realize equal rated load in four directions (radial, reverse radial, two lateral sides), supporting installation in horizontal, vertical, wall-mounted and inverted poses. Equipped with double-sided SS integrated dust-proof sealing gaskets to block dust, cutting fluid and fine debris, suitable for dusty, humid workshop environments. Built-in grease nipple for convenient relubrication; retainer structure prevents steel balls from falling off when separating slider from rail. Standard R short block size matches 20mm width LM rail, widely used for CNC machine tools, automation gantry, packaging equipment, textile machinery and precision positioning platforms requiring independent matching of rails and sliders.

Q1: What does GK stand for in HSR20R1SS GK?
A1: GK series means separate interchangeable type, slider and linear rail are sold individually without fixed matched set, free to combine any rail length and number of slidersTHK.

Q2: What preload grades are optional for HSR20R1SS GK?
A2: Normal clearance (standard), C1 light preload for low-vibration precision equipment, C3 medium preload for heavy-load high-rigidity machining equipment.

Q3: What is your standard delivery cycle for HSR series GK separate linear sliders?
A3: Stock standard sliders ship within 7–15 days; customized preload, stainless steel and special sealing versions depend on processing schedule.
