Professional FAQ: Linear Guide Selection & Engineering
Q1: What materials are offered for High Quality EG Bearing Linear Guides And Linear Slider?
A: EG series is primarily made from GCr15 bearing steel, with options for 440C and 304 stainless steel for cleanroom or corrosive settings.
Q2: What are the available block and guide sizes?
A: Sizes include EG15, EG20, EG25, EG30, and EG35, denoting guide width in millimeters (15 to 35mm).
Q3: What preload grades are supplied?
A: Standard options cover clearance (Z0), light-preload (Z1), and medium-preload (Z2) according to application demand.
Q4: What installation accuracy classes can be chosen?
A: Classes N (normal), H (high), P (precision), and UP (ultra-precision) are supported, aligning with JIS and ISO standards.
Q5: Are anti-drop or dust-preventing features available?
A: Yes, all EG series guides offer end-seals, dust plates, and can include anti-drop retainers for the balls to prevent accidental release.
Q6: Can EG series work in high-speed and high-load conditions?
A: Absolutely; the four-row design ensures robust load capacity and speeds up to 120 m/min, with stable performance in both dynamic and static states.
Q7: What lubrication protocols are recommended?
A: Use high-grade lithium or synthetic grease; lubrication intervals vary by size (around 50–80km travel) and environmental conditions.
