Подшипники из инновационных высокоэффективных пластмасс и полимеров, срок службы которых легко рассчитать, помогают клиентам компании igus, основанной в 1964 году в г. Кельн, Германия, повысить эффективность своей работы и сократить операционные расходы. Производственные мощности компании, на которых производятся как стандартные промышленные подшипники, так и подшипники по индивидуальным техническим заданиям, расположены в штате Род-Айленд, США.1. Straight running due to inner/outer link design 2. Low-noise running due to built-in brake in the stop-dogs 3. The undercut design ensures very high rigidity and load capacity 4. 15% more tensile strength (compared to the best in the old E4 series), better unsupported length due to improved vertical stop-dog system 5. Crossbars can be removed on both sides 6. Wide, cable-friendly plastic crossbars 7. Improved glide surfaces – long service life 8. Smooth outer contours, less dirt adhesion 9. Many interior separation options 10. Strain relief possible using strain relief separator within the mounting bracket 11. Pivoting mounting brackets which can be attached from any side 12. Alternatively available with Reverse Bend Radius, also on both sides (RBR version) E 4.21 series available in the ESD product range E 4.21 ESD seriesSeries E4.21 is suitable for the following types of applications: Vertical: hanging applications ? 40 m, standing applications ? 3 m horizontal: unsupported applications ? 2.5 m, gliding applications ? 120 m rotary motions: rotating applications possible, may require machining (machining rework is always required from rotation angles of 180°) When to use Series E4.21
  • When a robust e-chain® with 21 mm inner height is required
  • If an inner width up to 140 mm has to be implemented
  • For unsupported lengths up to 2.5 m and fill weight up to 4.0 kg/m
  • For long travels up to 120 m
  • Also suitable for side-mounted, standing and hanging applications
  • If the ability to have multiple options and attachment parts is required
  • If an opening crossbar with locking function is required
When not to use Series E4.21
  • When the e-chain® needs to be extremely quiet with low vibration E3.22 series
  • When the e-chain® will be used in cleanrooms (ISO Class 1) E3.22 series
  • When a one-side snap-open e-chain® or e-tube is required for cost reasons 1400 series , 1500 series , 1450 series, 1480 series
    • Series R117 , Series R118
