EGW15SA Linear Guide
EGW15SA Linear Guide
Product Description
The EGW15SA is a compact, low-profile flanged linear guide carriage from the EG Series (Low-Profile Ball Type), engineered for space-constrained, high-speed automation systems. Featuring a streamlined assembly height of 24 mm, this block combines a low vertical profile with a wide 52 mm flanged footprint to provide enhanced roll-moment stability.
Its four-row recirculating ball design delivers equal load-carrying capacity across radial, reverse-radial, and lateral orientations. The shortened 40.1 mm body length minimizes moving carriage mass to support rapid acceleration while increasing available travel stroke on the rail. The EGW15SA is fully compatible with standard EGR15 linear rails.
Product Advantages: EGW15SA Low-Profile Flanged Block
1.Wide-Stance Stability in Low-Profile Envelopes: The flanged footprint provides an expanded mounting base for enhanced lateral and roll-moment stability compared to narrow square blocks, all while maintaining a compact vertical assembly height.
2.Low Inertia for Dynamic Cycling: With a lightweight mass of approximately 0.12 kg, the shortened carriage minimizes moving inertia, reducing motor strain during rapid acceleration, deceleration, and high-frequency indexing.
3.Self-Aligning Architecture: Precision-engineered circular-arc raceways absorb minor mounting surface parallelism deviations through controlled elastic deformation of the rolling elements, preventing internal binding.
4.Smooth Kinematics & Minimal Stick-Slip: Symmetrical ball recirculation paths minimize rolling resistance, supporting smooth translation and significantly reducing stick-slip behavior during slow-speed or micro-stepping operations.
5.Integrated Sealing Protection: Standard elastomeric end seals and full-length bottom seals effectively retain internal lubricant while shielding bearing tracks from dust and airborne particulates.
